Hi i am currently being dermatologist with 2 cancers, Myeloma and Prostate cancer. I have a spot that is on the top side of my head it has been there since about last September it fades the reappears and sometimes bleeds, my doctor has referred me to a dermatologist . Just wondering how quickly these lesions spread? if it is SC how do they normally treat it? i am on maintenance drugs for my Myeloma any advice is welcome thanks
