I shave my head, and had sun poisoning on my scalp last year to where I had blisters, clear-to-yellow pus, and a thick layer of skin die and peel gradually from front to back. Does this almost surely destine me to get skin cancer on my scalp later in life? On a side note, my grandfather has been battling skin cancer on the top of his head/forehead for the past 3 years of so. p.s. Not sure that is matters at all, but I also had sun poising across my shoulders about 14 years ago, which actually resulted in blisters, pus, and bleeding. Thank you, Jeff
