7,12-Dimethylbenz(a)anthracene is an immunosuppressor and a powerful organ-specific laboratory carcinogen.^[2] Also known as 7,12-dimethylbenz[α]anthracene or DMBA, this substance is widely used in many research laboratories studying cancer. DMBA serves as a tumor initiator by making necessary mutations. Tumor promotion can be induced with treatments of TPA (12-O-tetradecanoylphorbol-13-acetate) in some models of two-stage carcinogenesis.^[3] This allows for a greatly accelerated rate of tumor growth, making many cancer studies possible.
