It runs in my family, and it almost took my Dad out in the early 80's. I guess I am just waiting for the day, but I do try to be careful, somewhat. I watch the ABC's, and have had several moles removed and tested with all negative results. I wish you only the best. I would recommend not having skin grafts to cover any wounds not on your immediate face, neck, hands, or arms. I know it is all personal preference; but my Father had a piece of skin shaved off of his upper thigh to cover the large sand dollar sized hole they took off the back of his shoulder. So not only did his shoulder absolutley kill him, but his leg hurt like a bltch too, and THE DAMN GRAFT FELL OFF after 3 days.
