Michelle, while I cannot respond to the treatments your Dad is getting for his cancer, I can reluctantly respond to the other part of your dilemnma. It seems his Doc is saying this is incurable. You can certainly seek a second opinion about his condition. If that opinion concurs, then you will have the chance to begin a dialog with your Dad [and other family members] about how to proceed for this point on. The attitude of all of the Oncologists and chemo Docs we were involved with was to keep administering treatment as long as the patient was willing to endure the process. In some cases, that goes on too long and serves no purpose. This is a very tough and scary position for youall. Wishing you the best. Amy in the Ozarks
