I usually just get small basal cell cancers that are quickly handled in the dermatologist's office, but lately have 3 that require the "Moh's Procedure" where it's rounds of cutting/checking under the scope.
I perhaps need to move to a twice-a-year checkup from the annual one I had been getting by with.
If you or family are prone to skin cancers, then a regular checkup is a great thing, but I'm not sure you need to get one unless you have some spots you're concerned about.
Am now in Mississippi where my doctor(s) are, not the greatest time of year to be here weather-wise, hoping the 'dome' breaks down soon.
