A major new study suggests that weight-loss injections could nearly halve the risk of cancers linked to obesity. Cancer specialists have hailed the research as “groundbreaking,” with the potential to usher in a “new era of preventive cancer medicine.” Obesity has been linked to 13 different types of cancer. Although losing weight is already known to lower cancer risk, scientists have found that weight-loss drugs offer additional protective benefits beyond simply reducing body weight. Researchers in Israel tracked 6,000 adults without a prior history of cancer, who either underwent bariatric surgery or used glucagon-like peptide-1 receptor agonists (GLP-1RAs) such as liraglutide (Saxenda), exenatide (Byetta), or dulaglutide (Trulicity). These medications mimic the GLP-1 hormone, helping lower blood sugar and increasing feelings of fullness.
