Are You a Lark or an Owl? Your Answer Determines Your Risk for Ovarian Cancer
LatestA study published in the Occupational and Environmental Medicine that sampled over 1,000 women—389 of whom were in the primary stages of the most common form of ovarian cancer—and 1,832 cancer-free women has determined that working night shifts increases the risk of ovarian cancer. The women interviewed are from 35 to 74 years old, and work in fields including health care, food service and office administration.
The International Agency for Research on Cancer had previously classified this type of shift work as a cancer trigger because it disrupts the body’s internal clock. Despite this, studies between shift work and breast cancer have always been inconclusive.
