Hello! I was diagnosed 10 years ago with endometrial cancer (Stage III) and had surgery and chemo and pelvic radiation. Three years later the cancer had metastasized to my lungs. Another round of chemo and various targeted radiations have followed. Ever since the first chemo, I have had mouth sores. Ever since trying L Glutamine I am essentially free of them, as it also works (for me) as a preventive when I begin to feel one coming. While the 'magic' solution gives some relief for a brief time, I found I did not need it with the capsules of L Glutamine, as the sores would go away overnight or by day 2, and, I learned to prevent them (only taking when I felt them coming on). I hope people will try it for themselves!
