Hello, My dad was diagnosed with Squamous Cell Lung Cancer in June 2012. He was staged 2b and had a right middle lobe lobectomy. He had one node out of 6 test positive for cancer and no other pet scan activity. He had 8 chemo treatments of cisplatin/gemzar with virtually no side effects except fatigue and thinning hair. He has been finished with his treatments about 3.5 weeks and they had him come in today for his first follow up Cat Scan. They found something new on the right lung in the "fissure" between where the bottom of the middle lobe and the top of the bottom lobe would have met. It measured 2 cm and there was not a post operation cat scan to compare it to. The doctor said it could be scar tissue, a reactive node or cancer. He has scheduled a pet scan for Monday, but as you all know too well, time equals anxiety. Has this happened to anyone else???? Has anyone else had scar tissue from the surgery?? We were told that it was a slow growing cancer so I don't understand how it could have kept growing right through chemo. Any advice would be so geatly appreciated.
