“Breast cancer is a type of cancer that starts in the breast. It can start in one or both breasts.

Cancer starts when cancer cells begin to grow out of control.

Breast cancer occurs almost entirely in women, but men can get breast cancer, too.

It’s important to understand that most breast lumps are benign and not cancer (malignant). Non-cancer breast tumors are abnormal growths, but they do not spread outside of the breast. They are not life threatening, but some types of benign breast lumps can increase a woman’s risk of getting breast cancer. Any breast lump or change needs to be checked by a health care professional to find out if it is benign or malignant (cancer) and if it might affect your future cancer risk.

Breast cancers can start from different parts of the breast. The breast is an organ that sits on top of the upper ribs and chest muscles consisting of mainly glands, ducts, fatty tissues,”
