Morning Jeff...I go once a year to get checked out as I do walk around shirtless a lot in the Spring Summer and Fall. Have had several spots burned off especially on my head. I now where a hat a lot. Have to keep onto these areas. My brother-in-law landed up with brain tumours which were cancerous and sread right through his body. The specialist could find any indication of where it started and the thought was it went in through his eye. So take heed everyone...wear your sunglasses and a hat.
