First your concern about skin cancer and treatments is normal and shared by all of us and we had the same questions.

Have your surgeon and or dermatologist explain all the different treatments and surgies with pros and cons. Make the decision yourself that sounds what is best for you.

I have chose MOHS for all of mine. And I do mean all of mine. I have had about 6-7 surgeries all MOHS for both Basal Cell and Squamonous (spell). Some like my nose take longer to heal but you would never know I had surgery there.

You won't feel anything after the numbing injection is done. If you have MOHS the surgeon will take only enough skin to have a free area with no cancer cells. To do this they remove what they thing from biopsies the amount to take and then send to pathology. Pathologist determines if there area any cancer cells left in the surrounding tissues taken. If not you are done and if yes surgeon does another surgical cut and process goes on until you are cancer free in biopsied area.

I chose this because you do not leave until there is no sign of cancer left and no returning for more treatments unless you have problems.
Good luck!!
