Three years after the first negative multi-target stool DNA test, according to a scientific investigation into the best time to screen for colorectal cancer using non-invasive methods for detecting the disease’s targets in the stool, there were no colorectal malignancies discovered.
Most of the tests that doctors use to diagnose cancer -- such as mammography, colonoscopy, and CT scans -- are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.
A machine learning algorithm helps accurately differentiate benign and premalignant colorectal polyps on CT colonography scans, according to a study published in the journal Radiology.
Statistical modeling developed by Oregon State University researchers has confirmed that changes to melanoma patients' gut microbiome led them to respond to a type of treatment capable of providing long-term benefit.
