Good post ScarbSUP.
On Tuesday I had no fewer than 35 (yes 35) Solar Kerotosis burnt off my arms and chest. This is not a one off it happens to me several times a year.
I have also had numerous operations, such as yours, to remove SCC's and BCC's from various parts of my anatomy. As well as this I use creams on my face to kill more of the little buggers.
Thankfully I have had no Melanomas and regular checks will keep it that way.
This comes from being a surfer and paddler for most of my 58 years, despite wearing wet shirts and sunscreens since they became available. This damage happens quickly and without you knowing it is happening. It will appear twenty years after the sun damage occurred.
So a word from the older and somewhat wiser. well in this regard anyway.
Get checked regularly.
Do as your doctor tells you.
Use a good quality water and sweat proof sunscreen all the time.
Wear a good quality wet shirt (rashie).
Spread the word to all water users you assocaite with.
But never, ever, ever stop what you love doing just be sensible in the sun. I am.
Thanks again.
Enjoy and stay wet.
