I'm not sure how many will answer, but I can tell you that there are quite a few people doing the Zelboraf. My husband is B-RAF negative. However, from most people I have heard that sensitivity to sunlight and mild rash seems to be common. If you would like more specific medical info on Mel try going to the melanoma resource foundation website. Many there are doing it, and they can give you more info.
Best wishes to you...
