Working night shifts? Think again!!

Smoking causes cancer – This is an accepted statement. How about night shifts?? Sounds whacky!! However the International agency for Research on Cancer, the WHO’s cancer wing is going to classify Night shifts as a possible carcinogen!
Anabolic steroids, UV radiation, diesel exhaust and now night shifts! Millions of people round the world, more so in the developed world, are working late night shifts and face the possible risk of developing cancers. Recent research has brought out the evidence that women who work for years in night shifts are more likely to develop breast cancer and men who work similarly are more likely to develop prostate cancers. In experimental studies animals who have their light-dark schedules switched grew more cancerous tumors and died much quicker.
Currently these studies have been done only on airline crews and nurses and more data is needed for a firm belief to gain foothold.
