Breast Cancer Molecular Subtypes Explained | ER PR HER2 Ki67 #breastcancer #breastcancerawareness

Breast cancer is not a single disease. It is classified into different molecular subtypes based on biomarkers such as ER, PR, HER2, and Ki67. These tests help doctors understand how breast cancer behaves and choose the right treatment. In this video, we explain breast cancer molecular subtypes in a simple and easy-to-understand way. Breast cancer testing includes immunohistochemistry (IHC) and sometimes FISH testing to determine whether the cancer is hormone-positive, HER2-positive, or triple-negative. 📌 What you will learn: • What are breast cancer molecular subtypes • ER (Estrogen Receptor) and PR (Progesterone Receptor) • HER2 positive and HER2 negative breast cancer • Ki67 proliferation index meaning • Immunohistochemistry (IHC) testing • FISH test and its importance • Hormone positive vs HER2 positive vs triple negative breast cancer Hormone receptor-positive cancers respond to hormonal therapy, HER2-positive cancers respond to targeted therapy, and triple-negative breast cancers often require chemotherapy. Understanding molecular subtypes is important for personalized breast cancer treatment and prognosis. This video simplifies complex pathology terms so patients and families can better understand their diagnosis and treatment journey. 📌IMPORTANT: Please seek urgent care for concerning breast symptoms.
