Havent been on this forum for months, my mother had tongue cancer, had major surgery and 7 wks radiotherapy, it did not work, the cancer travelled to groin lymph node and PET scan showed small deposits in liver and chest. she will die, but we dont know how long. Her cancer was rare - mucoepidurmoid in the tongue, usually a salivary gland cancer, but it has behaved v differently to what they expected.
