Car drivers 'risking skin cancer'

Drivers who spend a lot of time behind the wheel increase their risk of skin cancer, US work suggests.

Experts say repeated sun exposure through the car's side windows is to blame, and drivers who roll down the window are at even greater risk.

Most glass used for windows blocks UVB rays that cause sunburn but not deeper penetrating UVA rays.

The Saint Louis University School of Medicine team presented their work to the American Academy of Dermatology.
