October is breast cancer awareness month!
What is breast cancer?
Breast cancer is a disease where abnormal cells in the breast grow out of control and form tumors.
What are the common types?
• Invasive Ductal Carcinoma (IDC): Starts in the milk ducts and spreads to surrounding tissue; it is the most common form.
• Invasive Lobular Carcinoma (ILC): Starts in the milk-producing lobules and spreads to nearby tissue.
• Ductal Carcinoma in Situ (DCIS): A noninvasive stage where abnormal cells stay inside the milk duct.
What are the symptoms?
• A new lump or thickening in the breast or armpit.
• Changes in the size, shape, or appearance of the breast.
• Skin dimpling, puckering, or texture resembling an orange peel.
• Ni**le changes, such as turning inward (inverted) or unusual discharge.
• Redness, scaling, or dark discoloration of the skin.
What are the risk factors?
• Age: Risk increases as you get older, with most cases diagnosed in people over 50.
• Biological S*x: Women are diagnosed far more frequently than men, though men can also develop breast cancer.
• Genetics: Inherited mutations in genes like BRCA1 and BRCA2 significantly raise lifetime risk.
• Family History: Having close relatives with breast or ovarian cancer.
• Lifestyle and Environment: High alcohol intake, to***co use, obesity (particularly postmenopausal), and prior chest radiation exposure. In South Africa, resources and support are available through the Cancer Association of South Africa (CANSA).
Diagnosis and Treatment
• Detection & Testing: Screening tools include clinical breast exams, mammograms, ultrasounds, and core needle biopsies.
• Treatment Options: Approaches depend on the cancer type and stage, often combining surgery (lumpectomy or mastectomy), radiation therapy, chemotherapy, hormone (endocrine) therapy, or targeted drug therapies.
