Quoted from Frax:
I thought the places that set up these donor programs usually made it a point to NOT offer compensation for the donation...
I didn't say you were going to make $ by doing this. I said there are organizations that will make sure it doesn't create a financial hardship on you if you do decide to become a donor. Health insurance, for instance, is a non-issue. The recipients insurance will pay 100% of your medical costs. If neither party has insurance, the transplant center will usually find a way to absorb all the bills.
Reality is, "bone marrow" transplants are becoming increasingly rare. If marrow does need to be harvested from a donor, you are looking at a 24-48 hour hospital stay. Many blood cancers can be treated with peripheral stem cell transplants. If that's the case, the donor takes a day off work, gets hooked up to a machine not unlike donating blood, and the stem cells are harvested out of your blood for transplant. A simple 4 hour outpatient procedure.
Point being, financial hardship as a result of being a donor is pretty much a non-factor.
