Hi, as a transplant from a patient who has cancer to a healthy person, may it cause cancer? does this mean that cancer is contagious when i touch, eat, hug or drink with them?

Cancer: isn't contagious, and transplants are different in different organs, decision is complex and made case by case, best wishes

Not risky: I am assuming that you or someone you know received a transplant from a donor who later developed cancer. If the transplant material contained a cancer from the donor at the time of transplant, it could be passed on. This is really unlikely as donors are screened. Later physical contact you describe will not be a problem . You would need actual live tissue transfer.

Just no: Very rarely, a transplant recipient comes down with a cancer which genetically is composed of the cells of the donor who must have had the cancer when the transplant took place. This is possible because the cells were introduced into the bloodstream and the immune system was treated not to reject them. Husbands and wives don’t transmit cancers to each other. Stop worrying. Best wishes.
