contraception pills/fibrodenomas

Dear Prof. Zaidman, We were trying to get an appointment to see you, but it is not possible if the problem is not IVF. My daughter(24) has been taking pills for a year and a half when suddenly she felt lumps in her breasts. She had US, which showed 6 small lumps, one of them of 3cm. She underwent biopsy, the result was fibrodenomas.She is afraid of taking pills anymore, since they appeared when she was taking the pills. Ginecologysts say the pills don`t cause these changes, the breast surgent claimed the opposite.What should she do? She was taking the pills called Yaz. Please, help Thans .
