I have a small bump on my shoulder that appeared a month or so ago and has changed in size (grown). I have had a mole removed before for pre cancerous cells and am considered high risk due to lots of moles and freckles. I will get it checked out but because I live alone I was unable to get a photo to send my gp until now (dd home from unil) as it's in a awkward place (top of shoulder). Does it look like anything to worry about? Photos added.
