I haven't checked back on this post for about a week, but I very much appreciate all of your responses. In general, I didn't think it would be allowed for someone that had mets with chemo and radiation. That's why I wasn't sure for someone who only required surgery. It's good to know that at least my corneas would likely be taken in order to save someone's vision.

Not too long ago, I saw a piece about a woman who connected with an old highschool friend on FB and she found out that he needed a kidney. She decided to donate one of her kidneys to him. It was during the removal of the donor's kidney that they found out she had cancer. In this case, they were able to remove the cancer with clear margins and use the kidney for transplant. I was really surprised. She saved his life and he saved hers in return, otherwise she may not have found the cancer in its early stages. I love a happy endning!

Thanks again, everyone, for finding the answers. Take care and wishing you all good health this holiday season!
