My ex-husband has had prostrate cancer for some time and now the cancer has spread. He has been informed by his surgeon/doctor/medical adviser that he may have to undergo* bone marrow transplant.

My query is the following. He has two sons who presumably could be asked, if it was deemed necessary, to be donor(s) in the hope that one of them would be suitable. Would I be right in assuming that one could be a suitable candidate but the other not?? My main concern is that (I will not go into the background) that one of them is not his and he is not aware of that. I want it kept that way. If one was suitable and the other not I presume it would not be ethically and morally correct to have my ex-husband informed of this??

Grateful for any advice
