What Is Breast Cancer?

Breast cancer starts when cells in the breast begin to grow out of control. 
These cells usually form a tumor that can often be seen on an x-ray or felt as a
lump. The tumor is malignant (cancer) if the cells can grow into (invade)
surrounding tissues or spread (metastasize) to distant areas of the body. Breast
cancer occurs almost entirely in women, but men can get breast cancer too.

Cells in nearly any part of the body can become cancer and can spread to other areas of
the body. To learn more about Breast Cancer and its effects, try to check on the various posts to come on the breastmasters.
