Breast Cancer

Breast cancer begins when cells in the breast start to grow abnormally, forming a tumor that can often be felt as a lump or seen on an imaging scan. It most commonly begins in the ducts (ductal carcinoma) or the lobules (lobular carcinoma). Although it primarily affects women, men can also develop breast cancer.

Breast cancer can be invasive (spreads to surrounding tissues) or non-invasive (contained). Early detection plays a key role in successful treatment and survival.
