Women and Graveyard shifts

The shifting schedules of working women have been found to be a contributor to them being more susceptible to breast cancer. The population based study shows that people who work late at night while exposed to artificial lights increases greatly their risk to contracting the disease that infects millions of people around the world. The study shows that women who have worked at least once during the abnormal work schedules a decade before being diagnosed with breast cancer are 60% more likely to get them than those who work during the normal working hours. The possible links being studied are between melatonin, exposure to artificial light at night and irregular sleep patterns as the possible dots that have to be investigated for better understanding of their counteractions.
