Our local news just had a health segment about skin cancer, and reiterated: normal moles are smaller than a pencil eraser, brown, smooth, and have an even border . Diabetics are prone to difficulties in their legs and feet, but I can't see a skin cancer on the foot, being any worse there, than anywhere else on the body if you aren't diabetic. And if you have had it for years, and it never changed, then it would seem to be benign. However the full body check is an excellent idea for anyone, and especially if you are fair, or had severe sunburns. My husband has what you would think would be a melanoma, but it's been there all is life, and is just an ugly mole.
