🎧🎀MSRA DEEP DIVE:Breast Cancer — High-Yield Revision BreakdownWelcometo today’s comprehensive Deep Dive — we’re unpacking Breast Cancer, one of the most tested and high-yield topics foryour MSRA exam. 🚀 🔑Core MSRA RevisionSummary📌Definition• Malignant tumouroriginating in breast ducts (ductal carcinoma)or lobules (lobular carcinoma)• Divided into in situ (DCIS) or invasive subtypes• Includes Paget’s disease (nipple involvement) & inflammatory carcinoma (red, swollen breast)📌Causes & RiskFactors• Age(⬆ risk after 50)• Family history(first-degree relative = ↑ risk)• BRCA1/2 mutations (up to 85% lifetime risk)• Hormonal exposure:early menarche, late menopause, nulliparity, delayed childbirth, HRT, COCP• Obesity(postmenopause), sedentary lifestyle, Western diet, alcohol• Radiation exposure(esp. chest irradiation)• ✅ Breast implants do NOT increase risk📌Pathophysiology• DNA mutations →abnormal cell growth → invasion of surrounding tissue → lymphovascular spread →metastasis• Lymph node(axilla) & distant spread (bone, liver, lungs, brain)📌DifferentialDiagnosis• Fibroadenoma• Cysts• Fibrocysticchanges• Abscess / Mastitis• Fat necrosis📌Epidemiology (UKdata)• Most common cancer in the UK (15% of all cancers)• ~50,000 new femalecases/year• 99% in females;male breast cancer rare but worse prognosis• Upper outerquadrant = most common site• Lower incidence inmost socioeconomically deprived areas📌Symptoms & RedFlags• Painless breastlump• Nipple changes:inversion, discharge (esp. blood-stained)• Skin changes:dimpling, peau d'orange, redness• Axillary lump• Metastatic signs:bone pain, jaundice, breathlessness, lymphedema, weight loss, night sweats📌Screening• NHS screening:women aged 50-70 (mammography)• Less effectiveunder 40 (dense breast tissue)📌Investigations:Triple Assessment (EIB)1️⃣Examination2️⃣Imaging: Mammogram (>40), Ultrasound (<35), MRI(select cases)3️⃣Biopsy: Core biopsy (preferred), FNA for lymph nodes• Also: ER, PR, HER2receptor testing + Ki-67 proliferative index• Staging: AxillaryUS, CT, bone scan, PET-CT• TNM staging used• NICE 2-week waitreferral criteria highlighted📌Management (SRSApproach)🩺Surgery:• Lumpectomy (widelocal excision) or Mastectomy• Sentinel nodebiopsy / axillary clearance💡Radiotherapy:• Post-lumpectomy orfor local control💊Systemic Therapies:• Chemotherapy: Neoadjuvant/adjuvant• Hormonal Therapy: Tamoxifen, AromataseInhibitors (ER/PR+)• Targeted Therapy: Trastuzumab (HER2+), PARPinhibitors (BRCA), Pembrolizumab (triple negative)• Genomic testing: Oncotype DX, EndoPredict,PREDICT tool for personalised treatment• Bisphosphonates: Bone protection📌Prognosis• Early stage = excellent prognosis• 10-year survival~76% (UK) — doubled over 50 years• Survival best in55-64 age group• Male prognosispoorer (often later diagnosis)📌Complications• Local recurrence• Metastasis: Bone, liver, lungs, brain• Treatment sideeffects: chemo (fatigue, infection), radiotherapy (skin reaction), hormonal(hot flushes, joint pain), lymphedema• Emotional impact:anxiety, depression, body image issues• Menopausalsymptoms: non-hormonal management options highlighted (SSRIs, clonidine) 📚Extra MSRA RevisionResources📝 Revision Notes:https://www.passthemsra.com/topic/breast-cancer-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/breast-cancer-flashcards/💬 Accordion Q&A:https://www.passthemsra.com/topic/breast-cancer-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/breast-cancer-rapid-quiz/🎓 MSRA Obs + Gynae Course:https://www.passthemsra.com/courses/obstetrics-and-gynaecology-for-the-msra/🎯 Extra Quiz:https://www.passthemsra.com/quizzes/breast-cancer/ #MSRA #MSRARevision#BreastCancer #MSRAObsAndGynae #HighYieldMSRA #MSRAQuiz #PassTheMSRA#MSRAFlashcards #MSRAQuestionBank #MSRAQandA #MSRAAccordions #MSRAExams
