Pain in both breasts, especially right breast and new bumps on nipple how likely is this to be cancer and what else could it be?

CANCER DOUBTFUL: Breast cancer is usually not tender. Since both breasts are tender i suspect this is some degree of fibrocystic change. Now, i'm not sure what to make of new blemishes on the nipple, but, again, highly unlikely this is a cancerous process. Just discuss this with your doctor. Good luck.

Highly unlikely: In most cases, breast tenderness and pain, mastalgia, signals a noncancerous (benign) breast condition. Breast pain is rarely associated with breast cancer.Cyclic pain is the most common type of breast pain an may be caused by the normal monthly changes in hormones. If it persists, suggest you see your primary care physician. Best wishes.

Physiologic: Pain in cycle with your periods? This does not sound like breast cancer. Pain is not a normal symptom of breast cancer. This is the breast tissue responding to the hormones in your body related to your cycle.
