Surviving Stage 4 Sub Cutaneous Squamous Cell w/ Immunotherapy

I have a 25-year history of skin cancer with 15+ Mohs surgeries. I underwent a radical neck dissection to remove several lymph nodes followed by extensive radiation and chemotherapy, all of which didn’t cure the “beast” until a two-year Pfizer sCSC immunotherapy trial at MuSC Charleston SC saved me.
If anyone has the same skin cancer, look into this Pfizer trial, you may be a candidate. And if you've gone through the trial, touch base with me. God Bless!
