Hi Rick: welcome to this site.
My pathology report said I had modetately differntiated adenocarcinoma. I have had it twice. It was cut out twice. The first time in Jan 2004, and the second time In Feb 2005. The first time it was stage 1b and the second time it was stage 1a. It was found in my upper left lobe the first time, and then in my remaining left lung the second time. I did not have chemo the first time, but did the second time. I finished chemo last July. It was not too bad. I presumably am cancer free now.
I don't know for sure what moderately differentiated refers to, but I think it means that the nucleii of the cells are somewhat differentiated. I have no idea what that means in terms of the behavior of the cancer or its response to chemo. My cancer was kind of slow growing I think. My second cancer was first noticed as a possible nodule about 5 mm in size in May of 2004. It was cut out nearly 8 months later and was 1.5 cm in size.
I suspect that there is not much point in comparing cancers. I think that even though our cancers are similar types, how our respective bodies reponds to the cancer and the treatment can be very different. Cancer is a person specific disease. I guess that is why it is hard to find a cure.
We all tend to respond to treatment to one degree or another though.
I hope you find a treatment that produces awesome results Rick. One thing you can count on is that there are treatment options available to give you many good years ahead.
