Hi, 

so a couple of weeks ago I went to my GP with a mole I've had for at least a few years. I am in my early 20s, have never been on a sunbed and had very few sunburns that were by no means blistering. As the mole is in my belly button I cannot remember when I first saw it and what it looked like as it's such a hard to see area. The GP on first inspection said it looked like a normal mole, after looking through a dermascope he suggested that it had different colours and so referred me to a dermatologist - he thought that it was more than likely that the dermatologist would tell me it was nothing to worry about. 
Fast forward a week and the dermatologist had a look. She agreed that it was "irregular in colour" and "atypical". She said that sometimes moles that grow in areas like the scalp or the belly button are often atypical because it's a different type of skin there. I asked her if she thought it was fine and she answered that she didn't believe it to be melanoma but is scheduling for it's removal and testing anyway. She said it was best removing it. She then handed me a little booklet about skin cancer and pointed to the picture of a melonama varying in colour and said mine most identifies with that one because of its variation in colour. I told her I'd been very worried over the last week waiting for the appointment and she then said she hoped I was feeling reassured. 
 

I keep overthinking the fact that the dermatologist didn't say she thought it wasn't melanoma until I asked her if she thought it was ok, handing me a skin cancer leaflet and organising its removal and biopsy. 
sorry for the long post but needed to vent my worries
