“Cancer comes from our own cells. And so it’s more like guerrilla warfare — the immune system has trouble distinguishing the normal cells from the cancer cells,” said Dr. Patrick Hwu, melanoma chief at the University of Texas M.D. Anderson Cancer Center.
Researchers say that if they can develop something by which the immune system could recognize cancer as being bad, then our own bodies could take more of a role in combatting the disease.
