Understanding Breast Cancer: A Helpful Guide
Health Points
- Breast cancer can develop in any breast tissue and has distinct risk factors.
- Early signs may be subtle, making routine screenings important for detection.
- Both men and women can be affected, though it is more common in women.
Breast cancer occurs when cells in the breast begin to grow abnormally, often first appearing as a lump, skin changes, or other unusual symptoms. Most commonly found in the ducts or lobules, it can sometimes affect other tissues in the breast.
Cancer cells can spread to nearby tissues and eventually travel through the body via the lymph nodes under the arms. While rare in men, breast cancer does affect them as well.
Signs and Symptoms of Breast Cancer
Early breast cancer might not show noticeable symptoms, and sometimes tumors are only visible on a mammogram before they can be felt. When symptoms do arise, they may include lumps, changes in breast shape, unusual discharge, or skin alterations.
Not all lumps are cancerous, but it’s always wise to consult a healthcare professional if you notice new or unusual changes in your breast or underarm area.
Types of Breast Cancer
Breast cancer falls into two main categories: invasive, which spreads beyond its origin, and noninvasive, which stays contained. Types like ductal carcinoma in situ and lobular carcinoma in situ are noninvasive, while invasive ductal and lobular carcinomas are more common forms that can spread within the breast and beyond.
Some rare types include inflammatory breast cancer, Paget disease of the nipple, triple-negative breast cancer, and angiosarcoma. Knowing your specific type helps determine the best treatment plan.
How Common is Breast Cancer?
Breast cancer is the second most commonly diagnosed cancer in women, according to the CDC. It’s important to be aware of risks and symptoms for prompt detection and care.
Risk Factors for Breast Cancer
Several factors can increase breast cancer risk. Modifiable factors include alcohol use, hormone therapy, and lack of exercise. Genetic background, age (especially over 55), dense breast tissue, and family history are risk factors you cannot change.
If you have questions about your own risks or screening options, talk with your healthcare provider about the best plan for you. Stay informed, and remember—awareness is a powerful tool for staying well.
