I Found Out That I Had Aqueous Cell Carcanoma Of

I found out that I had aqueous cell carcanoma of the analysis canned. Details I had at least 3 Pet Scans, 31 treatments of readiation, and constant chemo for quite awhile. They said it was the old fashion chemo that had platinum in it. That was in 2010. They say I am cancer free now (thank god). But like around 2 or 2 and one half years. I now have copd and on oxygen. Never was on it before. I am told that Chemo or radiation can cause copd? I am so sad that my life is upside down. I just turned 62 and I have always been an on the go person. Any thing you can tell me would be appreciated. I feel life is o er for me. No more fun things to do?
