Lets look at this with some rationality. Malignant melanoma is a serious disease....when it advances. The people that die from this are the ones who dont pay attention to themselves and dont check for moles and changes to moles and ignore "that freckle that keeps bleeding and wont stop." Now, there's also amelanotic melanoma, uveal melanoma, subungual melanoma, nodular melanoma (all screenable very well) and of course mucosal melanoma (not so easy to find, but you may was well worry more about dying in a car accident, honestly.)
My father in law had melaoma on his back about 10-15 years ago. He went to the doctor regularly every 6 or 12 months to get checked. Doc was right away like "whoa whats that?!" when he got to that area. Took a punch biopsy. Called later..... "bad news is its melanoma, good news is its small and shallow and we'll take it out!" Boom, done.
Melanoma is like breast cancer in a way. If you go regularly for screening, and help by doing your own "screening," the chances of this laying you low are approaching zero.
Now go worry about an abdominal aortic aneurysm!
