Never-ending squamous cell cancers appearing on head and face

Definitely feel for you.
You may have a genetic predisposition as do I.
Nicotinamide is a D3 supplement and shows some promise in reducing Ak’s and squamous cell.
Photodynamic therapy on the face and neck is also good and it’s typically covered by insurance.
The chemical applied seems to target pre-cancer cells that are engaged with blue light.
I would like to do CO2 to my face and chest. It is more ablative and can take away years sun damage and has cosmetic positives.
It’s expensive though.
I am currently going through my own unfortunate diagnosis of a very aggressive, squamous cell on my forehead.
I am discussing doing Brachytherapy with my doctor.
Hope this helps:)
