What condition typically prevents organ donation?

The condition that typically prevents organ donation is related to severe health complications such as cancer or the loss of all blood. When an individual has active cancer, especially aggressive forms, the risk of cancerous cells spreading into donated organs is a significant concern. Organs from individuals with cancer can potentially lead to the transmission of malignancy to the recipient, which is a serious risk in transplantation. Additionally, the loss of all blood would indicate a critical state of health that renders the organs unsuitable for donation, as adequate oxygenated blood supply is essential for organ viability.

In contrast, minor health issues generally do not preclude organ donation, as many recipients have successfully received organs from donors with such conditions. Recent surgeries can also be acceptable, depending on the nature and timing of the procedure. Age alone is not a strict barrier to organ donation; individuals of various ages can be considered suitable donors if their organs are healthy and functional. Thus, while each scenario presents its own considerations, cancer and total blood loss represent definitive conditions that can render organs nonviable for donation.
