Hello there. Three years ago I had an insitu Melanoma removed from the top of my right arm. I am very freckly, got sun burned a lot when I was a child (I'm 56). Since the Melanoma was removed, I have covered myself in sun creams and covered up as much as possible whenever I've been out in the sun. Just recently however, I have noticed a change in the scar on my arm where the melanoma was removed from. It is very pink, the texture of it feels different and sporadically, I feel a 'sensation' in that area. I would be grateful if you could advise if you think any of these changes should be of concern to me please. Many thanks in advance.
