I have been dealing with both BCC and SCC over the years (actinic keratosis). My dermatologist is extremely thorough and I trust her explicitly. She takes many biopsies just to make sure her diagnosis is correct. For the most part she uses liquid nitrogen (freezing) the basil and has me do MOHS for the squamous. Thank the Lord I have never been diagnosed with a ‘melanoma ‘. Also, depending on the size of the BCC, she will use liquid nitrogen (freezing) or I have also used Efudex/Fluorouracil (5-FU) cream over a recommended period of time for a basil. I did use this chemo cream on my face. I had so much sun damage that my doctor was concerned it could eventually become cancerous. I treated 1/2 of my face at a time. Believe me, it was extremely painful and it took about 6 months to heal completely but the end result was amazing so I opted to treat the other side of my face. I’m 79 years old and yet my face is baby smooth. I even took progress pictures. My dermatologist now uses those pictures to explain the procedure to her patients so there are no surprises. I was amazed at all the people posting that they weren’t told much about the affects of this treatment.
To answer your question; I think I would want a 2nd opinion. You must remember to put yourself and your health first. Doctors are use to having their patients get 2nd options and then sometimes leaving. It’s your prerogative.
