Recently I was diagnosed with pre-cancerous sores in my vulva area. I had cancer in that area and surgery ten years ago. I was concerned but not fearful as I have been in Natural Health and knowing the body has an innate ability to heal itself. I discovered the Flash VUV light therapy device about two and a half weeks prior to my gynecology checkup. I used it twice a day and last week at my checkup my gynecologist told me that the precancerous sores are healed. Yay for the Flash. I also used it on my friend Mike. He had a pre-cancerous sore on his ear. Zapped it one time and it went away along with the pain. It was precancerous as the doctor had prescribed. What a validation for the Flash.
