I was diagnosed with melignant melanoma 10 years ago on my right arm. They origionally told me it was basal cell, no big deal, but the biopsy said otherwise. They told me the small surgery I had did not get it all, and they wanted to take a peice off my arm the size of a silver dollar down to the muscle and do lymph node testing. I refused everything., and was guaranteed that at the very LEAST it would regrow on my arm, but the worst was it would spread internally. I chose to use my lifelong passion, and treat it alternatively. Nothing ever came back on my arm, and I feel great 10 years later. I believe I got it from indoor tanning for 2 years. I still love the sun and being outdoors, but I no longer use commercial tanning lotions. I use powdered Ester C {i powder it} in an organic lotion. Hope this info is useful.
