Episcleritis is a condition that can cause redness in the eye, but it is typically not accompanied by pain.

Both episcleritis and scleritis can cause unilateral redness in the eye, tearing, and no sensitivity to light. However, a key difference between the two is that the use of phenylephrine or neosynephrine eye drops will cause the blood vessels in episcleritis to become pale, while this will not occur in scleritis.

In contrast, closed-angle glaucoma often presents with a painful, red eye that is unilateral. The cornea may appear hazy, and the pupil may be mid-dilated. Patients may also experience nausea, vomiting, and see halos around lights.

A stye, or hordeolum, is a bacterial infection of one of the glands in the eyelid. This can cause a tender, red bump on the edge of the eyelid.

Retrobulbar hemorrhage can occur due to various factors, such as AV malformation, trauma, or increased venous pressure. Symptoms include a painful, red eye that may protrude, particularly at night. Patients may also experience reduced vision, nausea, vomiting, and double vision.

Understanding Episcleritis

Episcleritis is a condition that involves the sudden onset of inflammation in the episclera of one or both eyes. While the majority of cases are idiopathic, there are some associated conditions such as inflammatory bowel disease and rheumatoid arthritis. Symptoms of episcleritis include a red eye, mild pain or irritation, watering, and mild photophobia. However, unlike scleritis, episcleritis is typically not painful.

One way to differentiate between the two conditions is by applying gentle pressure on the sclera. If the injected vessels are mobile, it is likely episcleritis. In contrast, scleritis involves deeper vessels that do not move. Phenylephrine drops may also be used to distinguish between the two conditions. If the eye redness improves after phenylephrine, a diagnosis of episcleritis can be made.

Approximately 50% of cases of episcleritis are bilateral. Treatment for episcleritis is typically conservative, with artificial tears sometimes being used. Understanding the symptoms and differences between episcleritis and scleritis can help individuals seek appropriate treatment and management for their eye condition.

The use of diclofenac is now prohibited for individuals with any type of cardiovascular ailment.

MHRA Guidance on Diclofenac and Cardiovascular Safety

The MHRA has updated its guidance on diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), after a Europe-wide review of cardiovascular safety. While it has been known for some time that NSAIDs may increase the risk of cardiovascular events, the evidence base has become clearer. Diclofenac is associated with a significantly higher risk of cardiovascular events compared to other NSAIDs. Therefore, it is contraindicated in patients with ischaemic heart disease, peripheral arterial disease, cerebrovascular disease, and congestive heart failure (New York Heart Association classification II-IV). Patients should switch from diclofenac to other NSAIDs such as naproxen or ibuprofen, except for topical diclofenac. Studies have shown that naproxen and low-dose ibuprofen have the best cardiovascular risk profiles of the NSAIDs.

The MHRA’s updated guidance on diclofenac and cardiovascular safety highlights the increased risk of cardiovascular events associated with this NSAID compared to other NSAIDs. Patients with certain conditions are advised to avoid diclofenac and switch to other NSAIDs. This guidance is important for healthcare professionals to consider when prescribing NSAIDs to patients with cardiovascular risk factors.

Placenta praevia is a condition where the placenta is located in the lower part of the uterus, either partially or completely. If the placenta covers the internal cervical os, it is classified as major praevia, while it is considered minor or partial if it does not. Bleeding can occur spontaneously, due to trauma, or during labor as the cervix opens.

The Royal College of Obstetricians and Gynaecologists recommends considering placenta praevia in all cases of vaginal bleeding after 20 weeks of pregnancy. Symptoms that increase suspicion of this condition include painless bleeding, a high presenting part, and abnormal fetal lie. A definitive diagnosis usually requires an ultrasound to determine the position of the placenta.
(RCOG Green-top Guideline No. 27)

In this case, the absence of pain makes placental abruption unlikely, and the normal appearance of the cervix rules out cervical trauma, cervical neoplasm, and inevitable miscarriage as the cause.

Understanding Placenta Praevia

Placenta praevia is a condition where the placenta is located wholly or partially in the lower uterine segment. It is a relatively rare condition, with only 5% of women having a low-lying placenta when scanned at 16-20 weeks gestation. However, the incidence at delivery is only 0.5%, as most placentas tend to rise away from the cervix.

There are several factors associated with placenta praevia, including multiparity, multiple pregnancy, and embryos implanting on a lower segment scar from a previous caesarean section. Clinical features of placenta praevia include shock in proportion to visible loss, no pain, a non-tender uterus, abnormal lie and presentation, and a usually normal fetal heart. Coagulation problems are rare, and small bleeds may occur before larger ones.

Diagnosis of placenta praevia should not involve digital vaginal examination before an ultrasound, as this may provoke severe haemorrhage. The condition is often picked up on routine 20-week abdominal ultrasounds, but the Royal College of Obstetricians and Gynaecologists recommends the use of transvaginal ultrasound for improved accuracy and safety. Placenta praevia is classified into four grades, with grade IV being the most severe, where the placenta completely covers the internal os.

In summary, placenta praevia is a rare condition that can have serious consequences if not diagnosed and managed appropriately. It is important for healthcare professionals to be aware of the associated factors and clinical features, and to use appropriate diagnostic methods for accurate grading and management.

Differentiating Eye Inflammations: Symptoms and Characteristics

Episcleritis is a mild inflammation that causes grittiness and tenderness on palpation, with sectorial redness that is deeper than conjunctivitis. Scleritis, on the other hand, causes severe pain, tenderness, and blueish-red tinge due to deeper inflamed vessels in the sclera. Conjunctivitis presents with superficial inflammation and is not tender to palpation. Iritis causes acute pain, photophobia, and circumcorneal redness, while keratitis also causes acute pain and circumcorneal redness, with fluorescein staining indicating corneal epithelial defect. Knowing these symptoms and characteristics can help in accurately diagnosing and treating eye inflammations.

Metastasis Patterns of Common Tumours

Metastasis, the spread of cancer cells from the primary tumour to other parts of the body, is a major factor in cancer progression and treatment. Different types of cancer have different patterns of metastasis. Here are some common tumours and their predilection for dissemination to specific organs:

– Breast, prostate, kidney, lung, thyroid: These tumours have a predilection for dissemination to bone.
– Kidney, sarcoma, lung, thyroid: Sarcoma most commonly metastasises to the lungs.
– Breast, prostate, kidney, lymphoma: Tumours that commonly metastasise to the brain include those of the breast, lung, prostate, kidney and thyroid.
– Lung, breast, prostate, thyroid, brain: Primary brain tumours rarely metastasise to other parts of the body.
– Thyroid, brain, lung, liver, breast: Primary liver tumours most commonly metastasise to the lung, portal vein and portal nodes.

Understanding the metastasis patterns of different tumours can help in early detection and targeted treatment.

The presence of a systolic murmur could indicate the possibility of aortic stenosis (AS). It is crucial to prioritize ruling out this condition as syncope, which is a late symptom, often occurs during physical activity in patients with AS.

Aortic Stenosis: Symptoms, Causes, and Management

Aortic stenosis is a condition characterized by the narrowing of the aortic valve, which can lead to various symptoms. These symptoms include chest pain, dyspnea, syncope, and a characteristic ejection systolic murmur that radiates to the carotids. Severe aortic stenosis can also cause a narrow pulse pressure, slow rising pulse, delayed ESM, soft/absent S2, S4, thrill, and left ventricular hypertrophy or failure. The most common causes of aortic stenosis are degenerative calcification in older patients and bicuspid aortic valve in younger patients.

If a patient is asymptomatic, observation is usually recommended. However, if the patient is symptomatic or has a valvular gradient greater than 40 mmHg with features such as left ventricular systolic dysfunction, valve replacement is necessary. Surgical AVR is the preferred treatment for young, low/medium operative risk patients, while TAVR is used for those with a high operative risk. Balloon valvuloplasty may be used in children without aortic valve calcification and in adults with critical aortic stenosis who are not fit for valve replacement.

In summary, aortic stenosis is a condition that can cause various symptoms and requires prompt management to prevent complications. The causes of aortic stenosis vary, and treatment options depend on the patient’s age, operative risk, and overall health.

When a seizure is suspected to be caused by eclampsia, the recommended first-line treatment is intravenous magnesium sulfate, given as a loading dose followed by an infusion. In the case of convulsive status epilepticus, intravenous lorazepam is the preferred in-hospital treatment, with phenytoin as an alternative if lorazepam is ineffective. Glucose may be administered if hypoglycemia is a contributing factor. It is not appropriate to administer oral medications to a patient with a decreased level of consciousness. (Adapted from BMJ Best Practice – Pre-eclampsia)

Understanding Eclampsia and its Treatment

Eclampsia is a condition that occurs when seizures develop in association with pre-eclampsia, a pregnancy-induced hypertension that is characterized by proteinuria and occurs after 20 weeks of gestation. To prevent seizures in patients with severe pre-eclampsia and treat seizures once they develop, magnesium sulphate is commonly used. However, it is important to note that this medication should only be given once a decision to deliver has been made. In cases of eclampsia, an IV bolus of 4g over 5-10 minutes should be given, followed by an infusion of 1g/hour. During treatment, it is crucial to monitor urine output, reflexes, respiratory rate, and oxygen saturations. Respiratory depression can occur, and calcium gluconate is the first-line treatment for magnesium sulphate-induced respiratory depression. Treatment should continue for 24 hours after the last seizure or delivery, as around 40% of seizures occur post-partum. Additionally, fluid restriction is necessary to avoid the potentially serious consequences of fluid overload.

In summary, understanding the development of eclampsia and its treatment is crucial in managing this potentially life-threatening condition. Magnesium sulphate is the primary medication used to prevent and treat seizures, but it should only be given once a decision to deliver has been made. Monitoring vital signs and urine output is essential during treatment, and calcium gluconate should be readily available in case of respiratory depression. Finally, fluid restriction is necessary to avoid complications associated with fluid overload.

Myocardial infarction (MI) is a serious condition that requires proper management to prevent further complications. In 2013, NICE released guidelines on the secondary prevention of MI. One of the key recommendations is the use of four drugs: dual antiplatelet therapy (aspirin plus a second antiplatelet agent), ACE inhibitor, beta-blocker, and statin. Patients are also advised to adopt a Mediterranean-style diet and engage in regular exercise. Sexual activity may resume four weeks after an uncomplicated MI, and PDE5 inhibitors may be used six months after the event.

Most patients with acute coronary syndrome are now given dual antiplatelet therapy, with ticagrelor and prasugrel being the preferred options. The treatment period for these drugs is 12 months, after which they should be stopped. However, this period may be adjusted for patients at high risk of bleeding or further ischaemic events. Additionally, patients with heart failure and left ventricular systolic dysfunction should be treated with an aldosterone antagonist within 3-14 days of the MI, preferably after ACE inhibitor therapy.

Overall, the NICE guidelines provide a comprehensive approach to the secondary prevention of MI. By following these recommendations, patients can reduce their risk of further complications and improve their overall health outcomes.

Herpes Zoster Ophthalmicus: Symptoms, Treatment, and Complications

Herpes zoster, commonly known as shingles, is a reactivation of the varicella-zoster virus that causes chickenpox. Herpes zoster ophthalmicus (HZO) occurs when the virus affects the trigeminal nerve, resulting in eye involvement in about 50% of cases. Symptoms include patchy erythema and grouped herpetiform vesicles, which may extend to the tip of the nose. Other ophthalmic manifestations include conjunctivitis, scleritis, keratitis, and optic neuritis. Urgent referral to ophthalmology is necessary in the presence of eye involvement, as it poses a risk to vision. Treatment involves oral aciclovir and topical aciclovir for severe eye infection. There is no recommendation for the use of carbamazepine in the management of post-herpetic neuralgia. Topical steroids are not indicated for herpes zoster infection. Complications of HZO include post-herpetic neuralgia and scarring. Aggressive treatment and follow-up monitoring are required for HZO due to the possibility of eye involvement.

Understanding Somatoform Disorders: Exploring Possible Diagnoses for a Patient with Medically Unexplained Symptoms

This patient presents with medically unexplained symptoms (MUS), which are collectively known as somatoform disorders. The chronicity and large number of diverse symptoms in this case suggest somatisation disorder, a condition that affects 5-10% of repeat attenders in specialist clinics. Somatisation disorder is more common in women than in men and tends to start in early adulthood. Treatment involves psychological interventions (e.g. CBT) and/or antidepressant medication, but patients are frequently reluctant to engage in these.

Other possible diagnoses for MUS include conversion disorder, hypochondriasis, and undifferentiated somatoform disorder. Conversion disorder presents with neurological symptoms, usually some type of loss of function, while hypochondriasis is associated with a persistent preoccupation to have one or more serious and progressive physical illnesses. In hypochondriasis, the patient puts emphasis on the presence of one (or more) determinate illness and on having it diagnosed. In somatisation disorder, such as in this vignette, the emphasis is on the symptoms (for which the patients seeks a medical explanation), rather than on a specific diagnosis. Undifferentiated somatoform disorder is used when the MUS are multiple and persistent, but the diagnostic criteria for somatisation disorder cannot be fulfilled.

Depression is an important co-morbidity in patients with somatoform disorders, but in this vignette, the combination of physical symptoms and the extensive and complex history of contact with primary and secondary services makes somatisation disorder the most likely diagnosis. It is particularly important to use a patient-centred, empathic interview style with patients with somatoform disorders to ensure they receive the appropriate care and support.

Sexually Transmitted Diseases: Causes and Symptoms

Sexually transmitted diseases (STDs) are infections that are spread through sexual contact. There are various types of STDs, each with its own set of symptoms and causes. Genital herpes is caused by herpes simplex viruses, with type 2 being responsible for the majority of cases. It can present as vesicular lesions around the genitals, rectum or mouth, but most individuals are asymptomatic. Granuloma inguinale is a chronic bacterial infection that results in nodular lesions that evolve into ulcers. Chancroid is a bacterial STD caused by Haemophilus ducreyi, characterised by painful necrotising genital ulcers. Primary syphilis is caused by the spirochaete Treponema pallidum, with lesions beginning as solitary, raised, firm, red papules that can be several centimetres in diameter. Lymphogranuloma venereum is an uncommon STD caused by Chlamydia trachomatis, characterised by self-limited genital papules or ulcers, followed by painful inguinal and/or femoral lymphadenopathy. Non-infectious causes include fixed drug reactions, Behçet’s disease, neoplasms and trauma. It is important to consider these alternative causes if evaluations for the infectious aetiologies do not lead to a diagnosis. HIV infection should always be considered and tested for.

Investigating and Diagnosing COPD

COPD is a condition that should be considered in patients over 35 years of age who are smokers or ex-smokers and have symptoms such as chronic cough, exertional breathlessness, or regular sputum production. To confirm a diagnosis of COPD, several investigations are recommended. These include post-bronchodilator spirometry to demonstrate airflow obstruction, a chest x-ray to exclude lung cancer and identify hyperinflation, bullae, or flat hemidiaphragm, a full blood count to exclude secondary polycythaemia, and a calculation of body mass index (BMI).

The severity of COPD is categorized based on the post-bronchodilator FEV1/FVC ratio. If the ratio is less than 70%, the patient is diagnosed with COPD. The severity of the condition is then determined based on the FEV1 value. Stage 1 is considered mild, and symptoms should be present to diagnose COPD in these patients. Stage 2 is moderate, Stage 3 is severe, and Stage 4 is very severe.

It is important to note that measuring peak expiratory flow is of limited value in COPD, as it may underestimate the degree of airflow obstruction. The grading system for COPD severity has changed following the 2010 NICE guidelines. If the FEV1 is greater than 80% predicted but the post-bronchodilator FEV1/FVC is less than 0.7, the patient is classified as Stage 1 – mild.

The presence of Babinski sign suggests the presence of a condition affecting the upper motor neurons. When the sole of the foot is stimulated with a blunt object, an atypical reflex is observed where the toes move upwards.

When ankle jerks are absent and extensor plantars are present, it is usually due to a lesion that affects both the upper and lower motor neurons. This can be caused by various conditions such as subacute combined degeneration of the cord, motor neuron disease, Friedreich’s ataxia, syringomyelia, taboparesis (syphilis), or a lesion in the conus medullaris. These conditions can lead to a loss of reflexes in the ankle and a specific type of reflex in the foot that indicates damage to both the upper and lower motor neurons. It is important to identify the underlying cause of these symptoms in order to provide appropriate treatment and management.

Erythema multiforme is a skin condition that is characterized by a rash that affects a small area of the body or the entire body surface. It can be caused by drugs or other factors. The exact cause of this condition is unknown. The rash typically appears on the hands and feet and is often raised. In some cases, the rash may also affect the mucous membranes. This is known as the major form of erythema multiforme.

Understanding Stevens-Johnson Syndrome

Stevens-Johnson syndrome is a severe reaction that affects both the skin and mucosa. It is usually caused by a drug reaction and is considered a separate entity from erythema multiforme. Common causes of Stevens-Johnson syndrome include penicillin, sulphonamides, lamotrigine, carbamazepine, phenytoin, allopurinol, NSAIDs, and oral contraceptive pills. The rash associated with this syndrome is typically maculopapular with target lesions, which may develop into vesicles or bullae. A positive Nikolsky sign is observed in erythematous areas, where blisters and erosions appear when the skin is gently rubbed. Mucosal involvement and systemic symptoms such as fever and arthralgia may also occur. Hospital admission is required for supportive treatment.

Understanding Chronic Kidney Disease Stages

Chronic kidney disease (CKD) is a condition where the kidneys gradually lose their function over time. To help diagnose and manage CKD, doctors use a staging system based on the glomerular filtration rate (GFR), which measures how well the kidneys are filtering waste from the blood.

There are five stages of CKD, each with a different GFR range and level of kidney function.

– Stage 1: GFR >90 ml/min/1.73 m2 (normal or high)
– Stage 2: GFR 60–89 ml/min/1.73 m2 (mildly decreased)
– Stage 3a: GFR 45–59 ml/min/1.73 m2 (mildly to moderately decreased)
– Stage 3b: GFR 30–44 ml/min/1.73 m2 (moderately to severely decreased)
– Stage 4: GFR 15–29 ml/min/1.73 m2 (severely decreased)
– Stage 5: GFR <15 ml/min/1.73 m2 (kidney failure) The 2008 NICE guideline on CKD recommends subdividing stage 3 into 3a and 3b, and adding the suffix ‘P’ to denote significant proteinuria at any stage. Significant proteinuria is defined as a urinary albumin : creatinine ratio (ACR) of 30 mg/mmol or higher. Understanding the stage of CKD can help doctors determine the appropriate treatment and management plan for their patients. It’s important for individuals with CKD to work closely with their healthcare team to monitor their kidney function and manage any related health issues.

Patients who exhibit tachycardia along with symptoms of shock, syncope, myocardial ischaemia, or heart failure should be administered up to three synchronised DC shocks. Synchronised DC cardioversion is recommended for tachycardia with haemodynamic instability, signs of myocardial ischaemia, heart failure, or syncope. In this case, the patient is displaying signs of heart failure, and the elevated troponin levels are likely due to tachycardia rather than acute myocardial infarction (MI). Adenosine is not suitable for this situation as it is used to manage supraventricular tachycardia (SVT) that is not associated with shock, syncope, myocardial ischaemia, or heart failure. Amiodarone may be considered in atrial fibrillation with a fast ventricular response if synchronised DC cardioversion is ineffective, but it would not be the most appropriate management option at this time. IV metoprolol (or oral bisoprolol) is used in fast atrial fibrillation not associated with shock, syncope, myocardial ischaemia, or heart failure. However, since this patient is exhibiting signs of heart failure, this is not the correct course of action.

Management of Peri-Arrest Tachycardias

The Resuscitation Council (UK) guidelines for the management of peri-arrest tachycardias have been simplified in the 2015 update. The previous separate algorithms for broad-complex tachycardia, narrow complex tachycardia, and atrial fibrillation have been replaced by a unified treatment algorithm. After basic ABC assessment, patients are classified as stable or unstable based on the presence of adverse signs such as hypotension, pallor, sweating, confusion, or impaired consciousness. If any of these signs are present, synchronised DC shocks should be given, up to a maximum of three shocks.

The treatment following this is based on whether the QRS complex is narrow or broad and whether the rhythm is regular or irregular. For broad-complex tachycardia, a loading dose of amiodarone followed by a 24-hour infusion is given if the rhythm is regular. If the rhythm is irregular, expert help should be sought as it could be due to atrial fibrillation with bundle branch block, atrial fibrillation with ventricular pre-excitation, or torsade de pointes.

For narrow-complex tachycardia, vagal manoeuvres followed by IV adenosine are given if the rhythm is regular. If unsuccessful, atrial flutter is considered, and rate control is achieved with beta-blockers. If the rhythm is irregular, it is likely due to atrial fibrillation, and electrical or chemical cardioversion is considered if the onset is less than 48 hours. Beta-blockers are usually the first-line treatment for rate control unless contraindicated. The full treatment algorithm can be found on the Resuscitation Council website.

Differentiating Heart Murmurs Based on Location and Type

Heart murmurs are abnormal sounds heard during a heartbeat and can indicate various cardiac conditions. The location and type of murmur can help differentiate between different conditions.

Ejection systolic murmur loudest over the 2nd intercostal space, right sternal edge: This is typical for aortic stenosis, which is more likely to occur in a bicuspid aortic valve. The murmur may radiate to the carotids. Pulmonary stenosis, hypertrophic obstructive cardiomyopathy, and atrial septal defect can also cause this type of murmur, but the location would be different.

Ejection systolic murmur loudest over the 2nd intercostal space, left sternal edge: This location is typical for pulmonary stenosis, not aortic stenosis. The patient’s history indicates symptomatic aortic stenosis, making this finding inconsistent.

Early diastolic murmur loudest over the 3rd intercostal space, left sternal edge: This type and location of murmur is typical for aortic regurgitation, not aortic stenosis. The location is Erb’s point, where S1 and S2 should both be heard.

Mid-diastolic murmur loudest over the apex: This type and location of murmur is typical for mitral stenosis, not aortic stenosis. The apex is the mitral area, located at the 5th intercostal space in the midclavicular line.

Pansystolic murmur loudest over the apex: This type and location of murmur is typical for mitral regurgitation, not aortic stenosis. The apex is the mitral area, located at the 5th intercostal space in the midclavicular line.

For mild croup, a single dose of oral dexamethasone (0.15 mg/kg) should be taken immediately, regardless of the severity. The severity of croup is determined by factors such as respiratory rate, respiratory distress, heart rate, O2 saturations, and exhaustion. Treatment for severe croup includes systemic dexamethasone and nebulized adrenaline (5ml of 1:1000), along with oxygen administration. Antibiotics should only be given if there is suspicion of an underlying bacterial infection. It is not recommended to perform an ENT exam due to the risk of an epiglottis diagnosis.

Understanding Croup: A Respiratory Infection in Infants and Toddlers

Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.

The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.

Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.

Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

Familial breast cancer is linked to ovarian cancer, not endometrial cancer.

Breast cancer screening is offered to women aged 50-70 years through the NHS Breast Screening Programme. Mammograms are provided every three years, and women over 70 years are encouraged to make their own appointments. While the effectiveness of breast screening is debated, it is estimated that the programme saves around 1,400 lives annually.

For those with familial breast cancer, NICE guidelines recommend referral if there is a family history of breast cancer with any of the following: diagnosis before age 40, bilateral breast cancer, male breast cancer, ovarian cancer, Jewish ancestry, sarcoma in a relative under 45 years, glioma or childhood adrenal cortical carcinomas, complicated patterns of multiple cancers at a young age, or paternal history of breast cancer with two or more relatives on the father’s side. Women at increased risk due to family history may be offered screening at a younger age. Referral to a breast clinic is recommended for those with a first-degree relative diagnosed with breast cancer before age 40, a first-degree male relative with breast cancer, a first-degree relative with bilateral breast cancer before age 50, two first-degree relatives or one first-degree and one second-degree relative with breast cancer, or a first- or second-degree relative with breast and ovarian cancer.

If a woman over the age of 30 presents with an unexplained breast lump, it is important to refer her urgently to the breast team using a suspected cancer pathway referral. It is important to inform the patient that they are being referred to a cancer service, but also explain that not all referrals to cancer services result in a cancer diagnosis. It is incorrect to perform a biopsy as an initial investigation, as this will be done in secondary care. While fibroadenoma is a common cause of breast lumps in young women, urgent referral to the breast team is necessary to rule out cancer in patients over 30 years old. It is not appropriate to schedule a GP review in 2 weeks, as this lump needs prompt investigation by the breast team.

In 2015, NICE released guidelines for referring individuals suspected of having breast cancer. If a person is 30 years or older and has an unexplained breast lump with or without pain, or if they are 50 years or older and have discharge, retraction, or other concerning changes in one nipple only, they should be referred using a suspected cancer pathway referral for an appointment within two weeks. If a person has skin changes that suggest breast cancer or is 30 years or older with an unexplained lump in the axilla, a suspected cancer pathway referral should also be considered. For individuals under 30 years old with an unexplained breast lump with or without pain, non-urgent referral should be considered.
