<s>[INST] My 12 year old granddaughter has developed excessive breasts. Ultrasound showing multiple large solid tumors. She has biopsies scheduled for next week in Michigan. Can you tell me what the incidence of this being carcinoma. Adult females have fibrocystic disease and fibroadenomas, but I ve never hear of a twelve year old. We are very worried. [/INST] Hi...even adolescent girls can have fibrocystic disease and fibroadenomas. this is occurring due to hormonal changes due to epidemiological shifts. The biopsy results will be conclusive. Do not worry. Nothing will be untreatable in todays science.Regards - Dr. Sumanth </s>
