I had fibroadenoma in 2009. in 2013 i found a cyst in the same breast. are these risk factors for cancer? a cyst can degenerate ? thanks

Not necessarily: Benign conditions of the breast like you have mentioned are quite common. Yet over 90% of such women will remain well and free of breast cancer. So you should quit worrying about breast cancer. Yet you should have an annual breast examination by your doctor. Once you get past 40 years of age, mammography can be added to your annual check ups. That is about all you need to know and do. Good luck.

Cysts are harmless: Simple cysts of the breast are harmless and "degeneration" has nothing to do with malignant change. Having had a fibroadenoma does put you at slightly greater statistical lifetime risk for breast cancer, but you'd simply do well to keep up surveillance, not ignoring self-exams. You mention abdominal obesity, fitness and weight loss may help you reduce your risk as well. Best wishes.
