Treatment really is a personal choice. When it comes to skin cancer, no treatment could lead to disfigurement, treatment can also lead to disfigurement. For me it was either a open ugly wound look, or a loss of halve an eyebrow, and hair where there never was before. (very fine but annoys my eye and needs trimming a lot).
I think it is better to know, one should never be afraid of knowledge even if that knowledge can cause fear.
