Breast gland tissue: The most common form of breast cancer arises from the cells that line the walls of the mild ducts (i.e. Ductal carcinoma in situ dcis or invasive ductal carcinoma). The next most common type is invasive lobular cancer a which arises from the lobules or sacs at the end of the milk ducts. Other origin tumors such as met aplastic are amuch more rare.

Breast cancer: Cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

I wish we knew!: We really don't know what causes breast cancer. We do know that women with a long exposure to estrogen are at a higher risk. If you started your period early, or never got pregnant, you have more estrogen exposure. But these are things you can't really change. However, alcohol intake is associated with breast cancer, so decrease how much you drink. And lower your body fat. And avoid bpa plastics.
