I too have just reveived the results of a PET scan which show several metastices in the lungs. It started in the tongue and initial sugery to remove was thought to be successful but was in transit to a spot under the jaw. Combined radio and chemo (twice daily for 7 weeks)did not kill the tumour under the jaw which now appears to be the source of metastices. I am seeing the radio-oncologist tomorrow about the options - it seems tat both radiotherapy to the lungs and surgery are options.
