Important Innovations: Cancer Vaccine Rids Body of Multiple Cancer Types in Mice


Could a cancer “vaccine” fight more than one kind of malignancy?

A new study in mice suggests it’s possible: A shot containing two compounds that stimulate the immune system was injected directly into tumors and killed those cancer cells.

Not only that, it also destroyed rogue cells from the tumors that had already traveled to other sites in the rodents’ bodies, researchers reported.

What’s more, they said this approach worked for lymphoma, breast cancer, colon cancer and the deadly skin cancer melanoma.

How did the researchers accomplish the feat?

“We found a way to get the body to reject cancer by putting stimulants of the immune system directly into the cancer,” said study author Dr. Ronald Levy, director of the lymphoma program at the Stanford Cancer Institute in California.
