Hi guys, my names Lynn and I am a 44 y/o dog groomer from hervey bay in qld. I was diognosed on xmas eve with secondary cancer in my lymph nodes under my armpit that were 'the size of texas". They were removed on new years eve and and biopsy showed squamous cells.I was given a PET scan last week at RBH and which showed nothing. Unknown primary. In a way I feel blessed but also frustrated. Radiation awaits me in the next few weeks. Has anyone else had any experience or knowledge on CUP?
