I sent fingernails to Johan Stegman in South Africa over 12,000 miles from Seabeck, Wa. My diagnosis from my Dr was Barrett’s Esophagus (BE). Johan tried a remote program for BE with no luck. He then tried Fibrosarcoma and Tania, his daughter saw 3 dark blurbs shrink. I went back to my Dr without telling him this and he did an Endoscope test, found three scars, biopsied them. Result all three were negative.
