Canadian Scientists Boost Cancer Immune Response

In the lab study, the scientists led by Dr. Pamela Ohashi combined interleukin -- a key component of the immune system -- with a viral vaccine to improve the ability of the cells of the immune system to attack tumors. They discovered the combination boosted immunity to tumors.

The study's co-author, Dr. Tak Mak, added: "The promise of using the body's own defenses to fight cancer is enormous. The day is coming when immunotherapy may help spare cancer patients the toxic side effects of traditional therapies and greatly improve their quality of life while treating the disease."
