Check with Doc: Breast masses are common. Most of the time they are benign. They should always be checked out with your doctor.

The findings that you described are commonly associated with cysts and can be affected by caffeine and also by shaving with lymph node changes in the breast or armpit. Cancer usually does not come and go. ...Read more
