Possible Skin Cancer? Mole has disappeared from my face but there is still a mark. I'm worried as I had kidney cancer last year.

Hi everyone

I had a mole that appeared suddenly around 9 months ago on my face, it got bigger and became crusty around the edges, looked a different from my other moles, so I got it checked by my GP, who took some pictures and measurements and it measured at 1/2cm and gave me some steroid cream.

1 month later the mole started to shrink in size, go crusty even more and then bleed and now it has disappeared and not raised at all, but there is still a mark there.

I am worried as I had Kidney Cancer 1 year ago and it doesn’t sit right with me. I have booked in to see my GP again, but that’s in 3 weeks time….

Any ideas what it could be? Could it be skin cancer? Do moles disappear on their own?

Thanks in advance
