I have stage one carcinoid small cell cancer of the lung. My lower right lobe was removed with no cancer found in my lymph nodes. I am in the process of recovery and still using oxygen. I had a PET scan with no cancer found. My oncologist wants me to do chemo. I am 75 and have multiple heart problems. I am afraid that my body will not be able to handle chemo. Has anyone in my situation turned down chemo and what were the results?
