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

That’s right, there are some exciting new treatments for cancer that don’t use radiation. These treatments include immunotherapy, which uses the body's own immune system to target and kill cancer cells. Immunotherapy can be very effective in treating certain types of cancers, including melanoma, kidney cancer, lung cancer, bladder cancer, and head and neck cancer. Other treatments include targeted therapy, which uses drugs that specifically block the growth of cancer cells, and gene therapy, which uses genes to repair or replace defective genes. All these therapies have been shown to be highly effective at treating many different types of cancers.
