Seeing metastasis before it happens: Tumor-derived extracellular vesicles for premetastatic niche imaging
Cancer is most dangerous not when it starts but when it spreads. Metastasis—the process by which cancer cells travel to and colonize distant organs—is responsible for the vast majority of cancer deaths. The problem is that ...
Patient-specific AI technique could make minimally invasive surgeries safer and more precise
Researchers have created a new technique that accurately and rapidly matches X-rays captured during surgery with a patient's preoperative 3D medical scan. This method could make it easier for clinicians to precisely guide ...
