For health professionals

Question


I know that testosterone therapy isn’t suitable in current or suspected breast cancer cases, but what about those with a history? How safe is testosterone in women who have had past, treated breast cancer? Given that a small amount of the therapy may be converted to oestrogen, is it safe?
