I've heard there is a new way to treat cancer that doesn't involve radiation. What is this treatment and is it effective?

This treatment involves using a type of immunotherapy called checkpoint blockade therapy, which blocks the proteins on immune cells that prevent them from attacking the tumor. Checkpoint blockade therapy has been shown to be very effective in treating many types of cancers, including melanoma, kidney cancer, lung cancer, and bladder cancer. It has also been approved for use in certain types of lymphoma.
