I was just diagnosed on 7/30/09 with the squamous cell variety luckily right now I am being told in situ. I have had a long history of achalasia and apparently was retaining food in my esophagus which probably has caused this problem. I get an EUS on the 19th and the dr is going to do more biopsies and hopefully suction out the cancer. My PET/CAT scans did not show lighting up in the esophagus or lymph nodes. So the thoracic dr told me it should be 1 cm or less. I will be staged then when he sees how deep anything is. Wondering if someone else on this board was dx'd with in situ and what happened. I am on another board and no one has come forward saying they have squamous cell yet. I am 65, the 70 in my name is for my son's birth year and feel pretty good. After reading the posts here, I know I am so lucky but guess in the back of my mind I know it can change. My best friend has Stage IV lung cancer but is NED and she told me today she was stage 1 for a very short while and went to Stage Iv pretty quickly.If anyone can give me their input from their experiences, I would much appreciate it.
