By Michael Irving September 28, 2021 Scientists have found that radiation therapy could be a less invasive treatment for arrhythmia Tolokonov/Depositphotos Scientists at the Washington University School of Medicine have made an intriguing discovery that could see radiation therapy become a less invasive treatment for heart arrhythmia. The technique seems to activate the heart cells...
by Dennis Thompson A pair of experimental tests could help doctors detect colon or prostate cancer with just a sample of blood or saliva. One test examines a person’s blood for four biomarkers linked to inflammation. In a small study, it outperformed the fecal blood test now used in colon cancer screening, said lead researcher Dr. Mona Eldeeb,...
