Researchers are claiming that women who suffer a series of bad luck events may be more prone to developing breast cancer.
The study also suggests that feeling happy and optimistic may reduce the risk of developing cancer. The survey involved 255 breast cancer patients and 367 healthy women aged 25 to 45.
AdvertisementResearchers from the Faculty of Health Sciences at Ben-Gurion University of the Negev, Israel questioned the women regarding their life experiences like levels of happiness, optimism, anxiety and depression.
All these were evaluated before they were diagnosed with cancer. The researchers report that suffering two or more adverse events increased the risk of developing breast cancer by 62 per cent. However women who were generally happy had 75% reduced risk of developing cancer.
"Young women who have been exposed to a number of negative life events should be considered an 'at-risk' group for breast cancer and should be treated accordingly," said study leader Dr Ronit Peled.
