Skin cancer survivor here of a rare form to head & neck area. Squamous cell that appeared quickly under my chin then spread within a few weeks to the bone requiring aggressive surgery, then recurrence and then very agressive radiation therapy. Best guess by experts is that my physiology and prior scars may have exacerbated the tumor. I'm an endurance athlete with a hyper-metabolism, but not a sun person at all. I survived with extensive knowledge of how to live life fully without fear of sun exposure. Cancer hit me at 34.
