Having had a melanoma scare I know the feeling. I am scheduled to have another spot excised next week…
However the big cause is sunburn.. not sun exposure. There has been an overreaction to sun exposure.. which has caused problems with lack of vitamin D which is created by sun exposure. It’s a complex issue and I suggest you research it and don’t throw the baby out with the bathwater. You should get sun exposure.. but never burn.. and barely tan.
There are MANY diseases which will become a death sentence if modern medicine is gone. That was life.. in the old days… and may be again… ( still is in parts of the 3rd world).
