Hello, Im not under 30, but am 44, but feel or felt under 30. My tumour was stage 4 with no lymph gland involvement. I didnt smoke, had a couple of glasses of wine some evenings and was fit and healthy. I did not fit the criteria at all, I also worked as a registerd nurse in gynae, I dint realise that oral cancer is as common as cervical cancer.hope you ok Ruth
