Drog, re melanoma, it's not the consistent exposure to sunlight that can cause it.
Just one day, sitting out, having a beer, walking down the road on a sunny day, playing sport, can be enough.
I get checked twice a year, if my skin cancer specialists finds, what he identifies as a basal cell carcinoma, he excises it (ie cuts it out and sends it to pathology).
His latest bit of kit actually looks through the levels of the skin to see if there are any cells which identify as carcinogenic.
he has identified maybe four or five, and cut them all out and they've all come back positive carcinomas. He also tells me that I should consider myself lucky as I didn't get to Aus until my early 20s, meaning I didn't bake myself as a teenager.
It's when you see people with parts of their face missing, no ears or the like that you realise what an terrible thing that it is.
When outside, particularly on sunny days, "slip, slop, slap" Slip on a shirt,(UV protective shirts), slap on some sunscreen, (SPF50 at least), and slap on a hat, Broad brimmed so it covers the face. Don't forget long sleeves when playing golf.
