Night shift a 'probable' carcinogen: WHO

Graveyard shifts could put workers in the grave
||Last Updated: 01/24/2008

The graveyard shift seems to be living up to its name.

Based on research that has found higher rates of breast and prostate cancer in women and men who work the night shift, the World Health Organization is adding overnight shift work to the list of probable carcinogens.

The long list of probable carcinogens includes UV rays, inorganic lead compounds, anabolic steroids and diesel exhaust fumes. The "probable" tag means the link to cancer is merely plausible, not proven.
