evidence: That surge has some doctors and researchers concerned that the daily bombardment of a variety of electromagnetic signals may increase our cancer risk. [...] When Apple released its Bluetooth AirPods in 2019, it raised questions about whether Bluetooth technology may raise cancer risk. Bluetooth uses the generally harmless non-ionizing type of electromagnetic waves. In fact, the American Cancer Society (ACS) says Bluetooth earpieces send out radiofrequency waves at significantly lower levels than even cell phones. Armin Ansari, PhD, a health physicist who leads the radiological assessment team at the U.S. Centers for Disease Control and Prevention (CDC) told Insider that people concerned about reducing cell phone radiation should consider wearing a Bluetooth headset or headphones.
