Dr. Amar Rewari Discusses Hidden Cancer Dangers on LIVE with Kelly and Mark

Dr. Amar Rewari, Chief of Radiation Oncology at Luminis Health, recently appeared on LIVE with Kelly and Mark during the show's "Hidden Danger Week," part of its "Simple Fixes for '26" series. In the segment, he sat down with hosts Kelly Ripa and Mark Consuelos to discuss hidden cancer risks lurking in common everyday habits.

Dr. Rewari emphasized that the goal isn't to live in fear — these are habits nearly everyone shares, and the associated risks develop over many years. More importantly, each comes with a simple fix.

Topics he covered included the link between very hot beverages and esophageal cancer, how chronic mouth irritations (like ill-fitting dentures or a chipped tooth) and poor oral hygiene can contribute to oral cavity cancers, and the role sleep plays in the body's ability to repair DNA damage. He also addressed indoor air quality, explaining the risks of firsthand, secondhand, and even thirdhand smoke, along with practical tips for safer use of scented candles and gas stoves.

Throughout the appearance, Dr. Rewari paired each risk with easy, actionable steps — from letting your coffee cool and staying on top of dental care to aiming for seven to nine hours of sleep and ventilating your kitchen.
