I think this question might be better addressed to your oncologist and your brother's doctor. There are so many medical questions that go into this. They would be the ones who have the information needed to make the call.

I don't know about living donors, but I asked the same question about whether to take the organ donor off my license. I was reminded that at that point, it's up to the procurement team whether to accept organs or not. And there are some things, such as corneas, that can usually be used unless the donor has cancer of the eye or some types of brain cancer. I decided I'd leave me as an organ donor and the doctors can figure it out, as I'll be beyond caring at that point anyway.

Here's some info from the American Cancer Society http://www.cancer.org/treatment/survivorshipduringandaftertreatment/can-i-donate-my-organs

Thanks Freebird for that link. I know I had to remove myself from the bone marrow registry once I went through chemo, however, after a certain time of being cancer free I can donate blood again, or so I was told at the blood bank.

Thanks to all. I keep forgetting to ask my oncologist and I do not want to give hope to my brother, just in case the answer is no.
Blessings

Thanks FreeBird. I read the info and it answered my questions.
Thanks again.

I called the donor registry for the state of California and was told my organs could still be donated. Marrow donors are refused but keep that "Yes" on your driver's license.

Interesting question. Next time the marrow donor registry contacts me for an information update I will be sure to give them news of my diagnosis. I forgot I was even in that registry. I'm keeping the "Yes" on my license. I truly hope they can find some useful parts in the event of my death.
