I was diagnosed with a malignant melanoma on my chest some 15 years ago, thanks to my wife who didn't like the look of the thing and more or less made me go and get it checked out.
Unfortunately, the first surgeon didn't get it all out so I had to go back a week or so later when they finally removed all traces of it
My only problems these days are Type II Diabetes, Gout, Hypertension & Tinnitus
So far so good...........
