|Cancers Diagnosed Earlier in Rural Patients, Say Medical School Researchers
Rural patients are often assumed to be the top truants in American medicine, not seeking medical attention until a condition is more advanced and less treatable. However, new Dartmouth Medical School research suggests that urban, not rural, patients are more likely to slip through the cracks—at least when it comes to colorectal and lung cancer.
