Back to the OP's question on organ donation, heres an edited summary of the American Cancer Society answer:
[quote]Acceptance of organs for donation is up to each organ procurement agency and the recipient. If you want to donate, it�s OK to list yourself as a donor on your driver�s license. .. If your cancer has been actively spreading, internal organs will not be taken. But if you die after being cancer-free for a long time, your organs may be used. Other tissues, such as skin, tendons, and bone can often be used, too. Careful testing of the organs and tissues is done at the time of death.

Even if other organs and tissues can�t be used, donating the corneas from your eyes is one way to offer help to others. Almost all people with cancer (except those with certain blood or eye cancers) can donate their corneas.[/quote]
