I just had my second mohs surgery and I've had to do the chemotherapy cream a few times. The bad news is that all my damage took place back in the 70's and 80's where I basically lived outside. I always put on plenty of sunscreen these days but it's too little, too late. The damage is already done and is now just starting to manifest itself.
I had an age spot on my right forearm for years. My dermatologist said it was not to worry about. Then I changed jobs and moved to another city, and let my regular dermatology visits lag.
Five years later, I started going back. 1st visit, they found melanoma in that age spot. And I went thru the surgery to have it removed, and the anxiety of waiting on the biopsy results. Lucky for me it was ruled stage 0
(in situ). I was lucky that it hadn't gotten into the lower layers of the skin yet.
My wakeup call to stop going out in the Sun. I know we are told that these skin cancers are due to the Sun damage from years ago, but, knock on wood, I have yet to get another basal, squamous or melanoma since I started avoiding the Sun.
