Breast cancer is a condition in which abnormal breast cells grow uncontrollably and can sometimes spread to other parts of the body. It can affect women and, less commonly, men. Understanding breast cancer and knowing the signs can encourage earlier medical attention.

Possible warning signs include a new breast or underarm lump, changes in breast size or shape, skin dimpling, persistent swelling, nipple inversion, unusual nipple discharge, or changes in the skin around the breast or nipple. However, these signs can also have causes that are not cancer, so a healthcare professional should assess any new or unusual change.

Some factors can increase breast cancer risk, including increasing age, certain inherited genetic changes, family history, previous breast conditions, alcohol use, and some hormonal or reproductive factors. Having a risk factor does not mean someone will develop breast cancer.

Healthy habits such as staying physically active, maintaining a healthy weight, limiting alcohol, and avoiding smoking can support overall health and may help reduce certain risks.

Breast awareness and recommended screening are also important. Screening can sometimes detect breast cancer before symptoms appear, but recommendations vary according to age, personal risk, and local guidelines.

If you notice a new or unusual breast change, do not ignore it or attempt to diagnose it yourself.

Breast cancer awareness is about knowledge, appropriate screening, early evaluation of changes, and taking action to protect your health.
