I had a mole on the side of my body since I remembered.Then over a month period it has changed colour , raised, and it's been itchy.  I had an appointment with  GP and been referred to a skin cancer clinic. (Waiting times due to pandemic are horrendous). Since I've seen GP that mole has fallen off and I'm now wondering what might caused it I kept this mole in the tissue as I was thinking it may be useful for a doctor.  I'm so worried that waiting times are so long now due to pandemic. Has anyone had similar issue to mine and maybe can advise what should I do? 

Thanks,

Sandra.
