Hello Gene, my dad has recently had surgery for melanoma on the back of his head and we are waiting to see if it has come back or not. If so he may need another surgery. I was wondering what was the lapse of time in between the 4 surgeries your husband had? My dad had one and it was very hard so I cant imagine 4! You guys are very tough. Hoping your husband is still cancer free, sincerely, Nick Hartmann.
