This mole used to be the same size as the little red spot. About 8 months ago it started growing and darkening. I’ve had referral to dermatologist so I’m just waiting for my appointment, but I’ve noticed it has now developed a white patch in the middle.

First image is from 3 weeks ago, second one is from this evening. Does anyone have any idea why it’s changing in this way?
