Sorry to hear about the cancer!!! I have several friends and family members that have gone through the same thing. They all say it is very painful and it leaves unsightly scars. I'm surprised I haven't had anything show up as I used to live to get a tan! Have you looked into laser surgery? They are able to help repair some skin problems...it might pay you to check into it. Also, be sure to take a daily multi-vitamin, you may want to take something that is targeted for the skin.
