Well, it if course depends on the cancer.
But the one I had involved putting cream on to the area which caused a scab. When the scab eventually came off the skin was totally clear underneath. That was before covid,bsona goid while ago.
My sister last year had a melanoma, which has involved surgery, and “infusions” over this last year. She has completed them and now goes for 3 monthly scans which have been all clear. The “infusions” are, according to my sisters oncologist “a game changer”.
My DIL had another type if skin cancer that just involved surgery - all clear
So you have reasons to be optimistic😊
Best of luck.
