@199,Thank you so much for the quick reply! I’ve been back to back chemo since last week in July and with exception for 1 week that is I saw the medical oncologist. The GAC is difficult yes and I would keep on it until some other treatment is offered, but my CA19-9 keeps rising exponentially, so I’m not sure it’s working on my lung 0.9 cm lung nodule. Your year of its stability gives me hope!!
