Small Cell Lung Cancer Limited, NED 3 years is this a recurrence? - 1264251

My father was diagnosed with SCLC Ltd in August of 2010, Fast forward to April 2011 after 6 Cycles of Chemo, Twice daily radiation and PCI he was NED. He remained NED for 3 years. Last Thursday he had his routine scans done and they found new activity in His umbilical area with an SUV of 7.9. My father recently had surgery to remove low grade tumors from his bladder and a hydrocele procedure done. 20 years ago he had a hernia in the same region that was operated on and over the past years my parents had seen it coming back (they thought his hernia was popping back out). It never came up as an issue on any of his other scans. We went to the Oncologist the next day so he can feel it he said its def a soft tissue mass and sent us to pathology for a Needle Biopsy, they took cells from two places and the pathologist said he didnt see any cancer, we were thrilled we went down to see the oncologist but he still was not convinced and send us to a surgeon immediately to have a procedure scheduled for removal of this mass. We are having it done tomorrow. Many have said that needle biopsies are notoriously unreliable and my dads Oncologist isnt convinced its not cancer and wants it out.

Here is my question, if the small cell was back, would it just show up right there after three years of nothing? my parents had noticed it over a years time, wouldnt it have spread everywhere? he had a clean PET with the exception of this. The SUV # is high and indicates cancer activity... what other reasons are there for the SUV# to be so high? the radiologist and Oncologist keep says its not a hernia but the pathologist that did the needle biopsy saw some evidence of hernia stuff (whatever that might be).

Any insight would be greatly appreciated as I am very very nervous and need to be prepared, my dad doesnt speak the language and my mom, the same. What do you think this is or could be.
