While mycophenolate is not primarily used as an anti-cancer agent, its immunosuppressive properties can be beneficial in certain cancer treatments. For instance, it is sometimes used in combination with other therapies to manage graft-versus-host disease (GVHD) in patients undergoing bone marrow transplantation. By suppressing the immune response, mycophenolate can help reduce the risk of GVHD, which is a common complication in such treatments.
