Breast cancer

Breast cancer is cancer arising in breast tissue. Cancer is simply a group of abnormal cells that have abnormal growth patterns.

What is breast cancer?

Breast cancer is cancer that starts in the tissues of the breast. Most breast cancers start in the tubes that move milk from the breast to the nipple and are known as ductal carcinoma.


A mastectomy is surgery to remove the entire breast in order to treat breast cancer. There are different types of mastectomies depending on the type of breast problem you have.


A lumpectomy, also known as breast conserving surgery, is surgery to remove a breast cancer from the breast along with some surrounding tissue.


Women who’ve been or will be treated for breast cancer may be at risk of developing a swelling of the arm, breast and chest called lymphedema.

Genetic testing

Since some kinds of cancer, including breast cancer, appear to be hereditary, genetic testing may serve as an advantage when thinking about specific health risks.
