Hi all. First time posting. About a month ago a mole appeared on my side. I have never had a mole there before. I know its common to get new moles as you get older. Withing 2 weeks it changed. It was raised up off the skin black scabby looking with a red ring round it. I saw my GP and she was worried about it. I got the 2 week referral. A few days later I got a letter throw the post with an appointment for the 26th April. Nearly 2 weeks after the original referral. Its now the 22nd and my mole has nearly completely gone. It looks like a old scab that's healed and it's a brown with a little redness. Do I still go to the appointment? And explain that its gone now. Or do I cancel the appointment. I'm really unsure of what to do. 

If I go to the appointment and it's nothing then I have wasted everyone's time and taken an appointment from someone that could have really needed it.

But I don't go and it is something more. It could be too late to catch it. I have read up somewhere that cancerous moles can get smaller and disappear. Mine got smaller first now it's gone. There's still a mark where it was but what if that's completely gone by the appointment. Then I have nothing to show. 

Any advice will be much appreciated thank u.
