Tumors that arise from exposure to mutagens, such as melanomas (UV light) and lung carcinomas (tobacco smoke) the number of mutations may be hundredfold greater than this. These altered proteins are known as neo-antigens

cytotoxic T cells can result in killing of the tumor cells by two different mechanisms

Fas-L on the cytotoxic T cell binds to its receptor, the Fas protein on the tumor cells, an apoptotic signaling pathway in the tumor cells becomes activated, which also leads to tumor cell death.
