Has anyone here had a suspicious mole removed?

Hi all! My sister had a mole removed yesterday and the doc said he was "worried." She had the same thing happen a few years ago and it turned out to be benign. I have an appt next week to have a couple suspicious moles looked at (I went to a free skin cancer screening and was told they should be followed up on) and I am SCARED! I am worried for both my sister and I. Has anyone on here had benign OR cancerous moles removed, and what happened? What did the moles look like (please don't post links to skin cancer websites because I've looked at every single one on the net- part of the reason I'm so scared!). One of my moles is on my , the other is on the side of my foot. At the screening they were named "dysplastic nevi" and "congenital nevus". Please share your experience so I can chill out! Thanks!
