Has anyone tried Libtayo for skin cancer treatment?

I HAVE ONE friend who had two or more surgeries, some radiation , for squamous cell cancer , these all failed him. A late mohs surgery tried, but in end, Libtayo saved him.

I am a 60 year old female, had advanced basal cell carcinoma for years.....had a year of Libtayo infusions that I stopped in August '25, got to say that it DID take off a nasty-looking big nodule on my poor nose!! But my doc said it would work on the lumpy BCC's first, then hopefully the flat ones. I switched to Erevidge pills 2 months ago, the side-effects are worse, but my two big open shoulder wounds are closing up. Flat BCC's don't seem to be budging, doc didn't think they would. I'm tired of meds!
