Tumor cells that border normal tissue are told to leave
...dary where a tumor meets normal tissue is the most dangerous part of a cancer according to a new study by scientists at Washington University School of Medicine in St. Louis. The researchers found that tumor cells bordering normal tissue receive signals that tell them to wander away from the tumor, allowing th...Preparing for flu pandemic: Pall breathing filters can help protect patients, healthcare workers
