Roughly 13%, or one in eight American women, will develop breast cancer in their lifetime. However, new advancements in detection and treatment have significantly increased survival rates. When breast cancer is identified in its earliest, localized stages, the survival rate is over 99%. For long-term breast health, paying attention to one's body, understanding risk factors, and scheduling screenings when concerns arise are crucial steps.
Breast cancer originates from changes in the DNA inside breast cells. These changes cause cells to mutate, become cancerous, and then divide and multiply to form a tumor. Several risk factors can increase the likelihood of these cellular mutations.
Some common risk factors are outside an individual's control. These include getting older, having specific genetic mutations like BRCA1 and BRCA2, a family history of breast cancer, and dense breast tissue. A personal history of breast cancer, race or ethnicity, starting menstruation before age 12, or beginning menopause after age 55 also contribute to risk. Additionally, past radiation therapy to the chest or certain non-cancerous breast conditions are recognized factors. Even though these elements cannot be changed, knowing one's breast cancer risk helps individuals and their doctors plan for early screenings tailored to health history and needs.
Other risk factors are within an individual's control. These include being overweight or obese, a lack of physical activity, and drinking alcohol. Using hormone therapy after menopause, taking certain types of birth control, and smoking are also identified as controllable factors that can influence breast cancer risk.
Regularly paying attention to any changes in the breasts is an important part of early detection. This can be done through visual checks in a mirror or physical checks using the pads of fingers to feel around the breast.
It is advisable to schedule an appointment with a primary care provider or gynecologist if any concerning signs or symptoms are noticed. These include a new lump in the breast or underarm, thickening or swelling of a part of the breast, or irritation or dimpling of the breast skin. Redness or flaky skin in the nipple area or breast, pulling in of the nipple, or pain in the nipple area also warrant medical attention. Other signs include nipple discharge other than breast milk, any change in the size or shape of the breast, or pain in any area of the breast.
Understanding one's personal breast cancer risk is an important step in protecting long-term health. While some risk factors cannot be changed, being aware of individual risk and adopting healthy lifestyle choices can help reduce the chances of developing breast cancer. Individuals should discuss their risk factors and screening needs with their healthcare provider to take proactive steps toward better breast health.
