@drhill, I'm tagging @eagleswings @jlstaloch and @sszantay, who have experience with brachytherapy, albeit for choroid melanoma.

My unerstanding is that brachytherapy can be an effective treatment for certain types of skin cancer, particularly basal cell and squamous cell carcinomas on the head and neck.

If I remember correctly from your other posts, the lesion is on your forehead. So, I get it that you're concerned about the damage it might do. This type of radiation travels only a short distance, so not much of it reaches nearby normal tissues with minimal side effects. It can avoid the need for reconstructive surgery.

When are you scheduled for treatment?
