After a study including 100,000 women, researchers conclude that those who developed breast cancer did not suffer more stress than those who did not.
Stress and traumatic events such as bereavement and divorce have been ruled out as causes of breast cancer, according to new research.
There is a common belief that stress can cause cancer, but the finding from scientists at the Institute of Cancer Research carries weight because it is from a very large study which began in 2003 and followed what happened to more than 100,000 healthy women over 40 years.
But the 1,783 of the 106,612 women who later developed breast cancer had not suffered significantly more stress or traumatic life events than those who remained cancer-free.
Delyth Morgan, chief executive at Breast Cancer Now which is funding the ongoing study, said: “Many women often question whether their breast cancer could have been triggered by stress or a particularly difficult experience. This groundbreaking study provides the most robust evidence to date that stress itself is unlikely to be a biological cause of the disease.
