Researchers have discovered an antibody which, when injected into mice, will bond with prostate cancer tissue and "initiate direct cell death" in it. If results carry over to humans, this discovery would almost be a cure to prostate cancer.

I say that it would almost be a cure for that particular type of cancer, because in initial trials with mice "F77 bonded with tissue where prostate cancer was the primary cancer in almost all cases (97 percent) and in tissue cores where the cancer had metastasized around 85 percent of the time." This means that while the antibody even attacked advanced stage cancer cells, it did not attack them all. Still, this is fantastic news and I hope that further research lives up to the initial optimism. [PhysOrg]

No, those aren't the happy, cancer-free mice. They're some lab rats photographed by jurvetson.
