Comprehensive guide to understanding and managing cancer
Cancer Overview
Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death. Cancer is caused by changes to genes that control the way our cells function, especially how they grow and divide.
What Happens in Cancer?
Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue called a tumor. Some cancers, like leukemia, do not form tumors but instead involve abnormal blood cells.
Main Types of Cancer
- Carcinomas: The most common type (e.g., breast, lung, prostate, colorectal cancers)
- Sarcomas: Cancers of connective tissues (bones, muscles, cartilage)
- Leukemias: Cancers of the blood and bone marrow
- Lymphomas: Cancers of the lymphatic system
- Central Nervous System Cancers: Cancers of the brain and spinal cord
Cancer Statistics
- Cancer is the second leading cause of death globally
- About 1 in 3 people will develop cancer in their lifetime
- Early detection improves survival rates significantly
- Approximately 30-50% of cancers can be prevented by healthy lifestyle choices
Breast Cancer
Breast cancer is cancer that forms in the cells of the breasts. After skin cancer, breast cancer is the most common cancer diagnosed in women in the United States. Breast cancer can occur in both men and women, but it's far more common in women.
Key Facts
- Most common cancer in women worldwide
- About 1 in 8 women will develop breast cancer
- Survival rates have improved significantly with early detection
- Risk factors include age, genetics, and lifestyle factors
- Regular screening can help detect breast cancer early
Types of Breast Cancer
- Ductal carcinoma in situ (DCIS): Non-invasive cancer in milk ducts
- Invasive ductal carcinoma: Most common type that spreads beyond ducts
- Invasive lobular carcinoma: Begins in milk-producing glands
- Triple-negative breast cancer: Aggressive form lacking common receptors
- Inflammatory breast cancer: Rare and aggressive type
Breast Cancer: Symptoms
Common Symptoms
- A breast lump or thickening that feels different from surrounding tissue
- Change in size, shape or appearance of a breast
- Changes to the skin over the breast, such as dimpling
- A newly inverted nipple
- Peeling, scaling, crusting or flaking of the pigmented area of skin around the nipple
- Redness or pitting of the skin over your breast
- Persistent breast pain or tenderness
- Swelling in the armpit or around the collarbone
When to See a Doctor
If you find a lump or other change in your breast — even if a recent mammogram was normal — make an appointment with your doctor for prompt evaluation. Most breast lumps aren't cancerous, but it's important to have them evaluated promptly.
Breast Cancer: Diagnosis
Breast cancer diagnosis begins with a physical exam and may include imaging tests and biopsy procedures.
Diagnostic Tests
- Mammogram: X-ray of the breast (screening and diagnostic)
- Breast ultrasound: Uses sound waves to produce images
- Breast MRI: Magnetic resonance imaging of the breast
- Biopsy: Removing a sample of breast cells for testing
- Lab tests: Analyzing cancer cells for receptors
Staging
If breast cancer is diagnosed, staging tests determine the extent (stage) of cancer:
- Stage 0: Non-invasive (DCIS)
- Stage I: Early stage invasive breast cancer
- Stage II: Larger tumor or spread to few lymph nodes
- Stage III: Locally advanced cancer
- Stage IV: Metastatic breast cancer
Breast Cancer: Treatment Options
Breast cancer treatment depends on the type of breast cancer, its stage, and other factors. Treatment often involves a combination of approaches.
Surgical Options
- Lumpectomy: Removing the tumor and small margin of healthy tissue
- Mastectomy: Removing all breast tissue (simple or radical)
- Sentinel node biopsy: Removing first few lymph nodes near tumor
- Axillary lymph node dissection: Removing many lymph nodes
- Reconstruction: Breast reconstruction after mastectomy
Radiation Therapy
Uses high-powered energy beams to kill cancer cells. Often used after lumpectomy.
Chemotherapy
Uses drugs to destroy fast-growing cells. May be used before surgery (neoadjuvant) or after (adjuvant).
Targeted Therapy
Drugs that attack specific abnormalities in cancer cells (e.g., HER2-positive drugs).
Hormone Therapy
For hormone receptor-positive cancers to block hormone effects on cancer cells.
Immunotherapy
Uses your immune system to fight cancer, for certain types of breast cancer.
Breast Cancer: Prevention
While there's no sure way to prevent breast cancer, you can reduce your risk through lifestyle changes and early detection.
Risk Reduction Strategies
