The breakthrough comes from researchers at Cornell University who created a protein with one lone goal, kill cancer cells.
The BBC calls the protein "cancer-killing sticky balls," due to the nature of how they work.
Called TRAIL, the balls flow through the bloodstream attached to white blood cells. But when they come in contact with active cancer cells they destroy them.
The Cornell Chronicle says “these circulating cancer cells are doomed.”
The journal Proceedings of the National Academy of Sciences reports the study’s lead author said “90% of cancer deaths are related to metastases, but now we’ve found a way to dispatch an army of killer white blood cells that cause apoptosis, the cancer cell’s own death, obliterating them from the bloodstream.”
He continued “when surrounded by these guys, it becomes nearly impossible for the cancer cell to escape.”
Scientists call the results “dramatic,” but warn early testing has been restricted to mice and blood samples and more thorough research needs to be done.
