I had surgery and also was pronounced "cured" by my surgeon and Pulmonary Specialist. Both of them, plus my general doctor advised follow up CTs/or xrays every 3 months for 3 years.
My Pulmononary Specialist would have been happy to do the follow ups for me and in fact told me I didn't need an Oncologist, but he was 4 hours away and I wanted to find someone closer. I found an Oncologist here in town who, on my first visit, started discussing putting a port in my chest and starting chemo for 6 months. There was a study done last May that suggested that adjuvent chemo after surgery improved the survival rate among lung cancer patients.
I thought about what I wanted to do and decided to stick with the doctors that I trusted, who advised AGAINST adjuvent chemo. Although there are mixed opinions about this, the more that I have researched, the more that it appears that adjuvent chemo does nothing for Stage 1A lung cancer. There was a later study done in Italy which clearly stated that while adjuvent chemo was beneficial for Stage 1B and higher cancers, there was no evidence of benefit for Stage 1A patients.
I guess adjuvent chemo is a matter of choice but people on here that are smarter than me told me to stick with the doctor's opinions that I trusted. That's what I ended up doing and I have no regrets.......
