Thanks for the information Doc Alan. We have posters displayed at work showing photos of different types of skin lesions and moles which I find very helpful. Having lived abroad as a child/ teenager in several hot countries, I am aware of the dangers and do regularly check for changes in skin pigment, etc.

Just before I went to Mexico a couple of years ago, I became aware of a change in a small mole that I'd had on my forehead since birth, I saw a consultant, he thought it wasn't serious but made arrangements to remove it as a precaution after I came back from holiday. Whilst on holiday I wore a large straw hat to protect my head and face from the strong sunrays and it was the best thing I could have done. The hat kept rubbing on the mole, made it bleed, scabbed over and eventually it came off so I didn't need surgery. I was very lucky and don't even have a mark to show where it had been but wouldn't hesitate to seek advice again if I spotted anything else that looked suspicious.
