Hello! I’m 43 years old and found a 5 cm/s lump , had scan , mammogram and core biopsy . Last week during my appointment doctor said my biopsy came B3 and booked me to have a wide local excision n t week . This is the third time I’ll have surgery to remove fibroadenoma ( never this big ) but this is the first time my Biopsy is B3 . I lost 5 kilos in one month due to stress. Does B3 means something else?
