Three habits may increase cancer risk - doctors' warning

Doctors warn that three everyday habits may increase the risk of developing cancer: using a smartphone before bed, sitting by the window on flights, and consuming very hot drinks. These are factors that, with prolonged exposure, may elevate risks, not a guaranteed cause.

Doctors warn that three everyday habits may increase the risk of developing cancer. The first is using a smartphone before bed: screen light suppresses the production of melatonin, which regulates the sleep cycle, and its long-term deficiency is linked to an increased risk of tumors. The second is sitting by the window on flights: UVA radiation penetrates through the glass, associated with premature skin aging and the risk of skin cancer. The third is consuming very hot drinks and foods (above 65°C), which irritate the esophagus and, with regular exposure, can lead to chronic mucosal damage and an increased risk of esophageal cancer. The authors emphasize that these are risk factors with prolonged exposure, not a guaranteed cause of cancer.
