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, men can also get it too.


 What is Breast


  • Skin changes, such as swelling, redness, or other visible differences in one or both breasts



  -Most breast cancers begin in the ducts that carry milk to the nipple (ductal cancers). Some start in the glands that make breast milk (lobular cancers). There are also other types of breast cancer that are less common.



A risk factor is anything that affects your chance of getting a disease, such as cancer. But having a risk factor, or even many, does not mean that you are sure to get the disease. While you can’t change some breast cancer risk factors—family history and aging, for example—there are some risk factors that you can control. 

Risk Factors 

-temporary swelling of the breast.


-breast tenderness.


-hardness due to scar tissue that can form at the site of the incision.


-wound infection or bleeding.


-swelling of the arm due to lymph node removal, called lymphedema.
