Breast cancer happens when cells in your breast grow abnormally and out of control. The cancer cells can spread to other parts of your body.
You're more likely to get breast cancer as you get older.
Breast cancer is the second most common type of cancer in women. Men can also get breast cancer, but this is rare.
