12 symptoms of breast cancer: what to look for?
In 2007, the world health organization published a report in which its experts stated that the night work leads to the development of disturbances in the biorhythms of the body and increases the chances of developing cancer, including breast cancer. These findings, as it was argued, scientists were obtained during the observation of the incidence of breast cancer in animals, whose cycles of sleep and wakefulness was broken.
Later, these conclusions were questioned — the medical team from Oxford have analyzed the statistics of three major projects on observations of the health of women, and found no hints that the night’s work makes them more vulnerable to cancer.
