If i have breast pain and heaviness for about 2 weeks then nothing for about 6 months, then it does it again, what are chances of breast cancer?

Not Br Cancer: The presence of a malignant lesion of the breast is never associated with heaviness and pain following which symptoms subside. Malignancies progress as well as symptoms. The effect of hormones on the breast at age 31 are usually associated with swelling of the milk ducts and breast pain as well as heaviness. At age 31, evaluation is by physical exam and sono, not mammography until age 35.

11% - every woman!: Without knowing more about your family and personal history of breast disease, your lifetime chance of breast cancer is 11%, the same as all women. Quitting smoking is something that you can quit to reduce your risk of cancer and other breast diseases like infections. The heaviness is likely related to stretching of the milk making tissue from excess hormones, as previous Dr. suggests. Health!
