Thanks for the support, Mark.

Fortunately, it isn't so much a choice that I face right now. The fact of the matter is, I and my doctors did really well in getting rid of the appearance of this disease (who knows what the scan will show). Now I just want to do what I can to make sure that it doesn't return. So I am looking at a variety of things and sources and strategies. Good diet, exercise and attitude seem to be the front-runners ;-)

Whether this is really "bad" stuff, I think that is unlikely. It is an MTD study (Maximum Tolerable Dose), but the underlying drug, Erlotinib, has been approved as a cancer fighting drug on the second or third line.

I have begun to wonder why this substance was chosen, given that it is not considered a first-line fighter.
