I had mohs surgery for squamous cell cancer on my hand along my thumb. It was very interesting! It gave me peace of mind to have them take a section at a time and examine it under a microscope and to keep cutting until the skin was clear. There was no pain after being number up. The incision was much smaller then one I had for another squamous area on my arm. That scar is really long and I did not know if they had gotten all of the cancer until the lab examined everything. That surgery was not mohs. Hopefully this will help someone.
