Israeli scientists say they’ve created a way to treat cancer in mice that is so precise, it’s like using “tiny scissors” to target the cells, according to a report. “This is the first study in the world to prove that the CRISPR genome editing system, which works by cutting DNA, can effectively be used to treat cancer in an animal,” Professor Dan Peer, a cancer expert from Tel Aviv University told the Times of Israel. Peer’s research was published last week in the Science Advances journal. “There are no side effects, and we believe that a cancer cell treated in this way will never become active again.” Peer told the news outlet, adding, “This technology can extend the life expectancy of cancer patients and we hope, one day, cure the disease.”
