Azathioprine
Summary
An immunosuppressive medication used after organ transplant. Associated with non-Hodgkin lymphoma and skin cancer.
Detail
Azathioprine is Group 1 with sufficient evidence for non-Hodgkin lymphoma and non-melanoma skin cancer. Used after organ transplant and for some autoimmune conditions. Transplant recipients as a group have increased risks of several cancers (the immunosuppression itself is the carcinogenic exposure). Questions about whether azathioprine is appropriate are clinical decisions between a patient and their care team.
