There's growing debate about a government panel's new guidelines for mammograms. But what if you never even had to worry about getting breast cancer? That reality is closer than you think, giving survivors like Jamie Lish a shot at hope. After six months of treatment, doctors now declare Jamie cancer free, but she still worries. "There's definitely a shelf back here in my mind that holds that thought is this going to come back? Am I going to have to go through this again?" she says.

Scientists at the University of Washington are testing a breast cancer vaccine. It targets protein specific HER-2 positive breast cancers. Those account for up to 25 percent.

Dr. Theodore walters is the research director at St. Luke's Mountain State Tumor Institute. He believes the cure for any cancer lies in our own immune system. Dr. Walters says a breast cancer vaccine will trick the body into doing what's right. "Cancer cells are really our own bodies cells with minor variations. So our body doesn't recognize they're foreign. So it doesn't make antibodies against them." says Walters.

To change that, scientists take a piece of the tumor, process it in a lab to make it an invader the body will react to and then inject it back into the patient. If it works, breast cancer survivors would never relapse. Dr. Walters says the breast cancer vaccine is still about five years away from being ready.
