<human>: I've heard there is a new way to treat cancer that doesn't involve radiation. What is this treatment and is it effective?
<bot>: That’s right, there are some new treatments for cancer that don’t involve radiation. These include immunotherapy, which uses the body’s own immune system to fight cancer cells, and targeted therapies, which use drugs designed to block specific proteins in the cancer cell. Both of these treatments have been shown to be very effective at treating certain types of cancer, but they are not yet available for all cancers.
