<s>[INST] am 17years and have two fibroadenomas. The left one is bigger than the right one and the left one is paining me. Is fibroadenoma painful and how long does it takes to go? What is the treatment for it. Can it develop into breast cancer? Or does it increase breast cancer? [/INST] Hi...it is a non malignant condition and does not predisposes to malignancy...take vit e and primrose oil...it will take a few months to resolve..you may also take analgesic for the pain...Dr. Ashish Verma </s>
