Oh man, that’s so awful! Seriously! I am sorry you have been going through this! I have an in-law who had it and still careful, but he only had it the one time some years ago.
My Dad kept getting squamous cell carcinomas and also melanomas.
I don’t know if it helps or not for Merkel cell, but I found this in the NEJM and asked his surgeon about it and he said he had seen it, too, and enthusiastically recommended it (Vitamin B3 prevents recurrence of squamous cell by 70%). This is a quality study:

NAC is effective against non-metastatic melanoma cell lines, but can actually cause proliferation of metastatic cells, as it interferes with the body’s natural cytotoxic T cells. Resveratrol is effective against both:

In case they have the same effect in Merkel cell, something to consider and discuss with your doctor. (As in, you might want to think twice about taking NAC without asking your doctor about it first.)
The above is not anywhere near the calibre of the NEJM study. There are mainly only in vitro and mouse studies available on NAC and Resveratrol re skin cancers. Still, something to consider.
I’ll research that, thanks.
Yeah, the first I became aware of it was one on my mother’s arm. She was doing nothing about it, so I set up an appt with a dermatologist. As soon as I saw one on me...I knew what it was...and was quick to respond. I also have a standing visit with the doctor every six months. Its not so bad because I stay on top of it.
Thanks again for the info.
