How about seeing a dermatologist? If you suspect a certain area where the melanoma started, insist on that area be tested and proven not to be skin cancer. I heard your post, and I have gone through nearly the same exact circumstance. My doctor, and a second doctor refused to believe I was ill. I am now beginning to treat myself by natural methods, and seeing a natural medicine doctor. I really advise you to begin some kind of treatment regardless of what your doctors refuse to believe or fail to detect. You know your body better than anyone.
