Stress 'can cause cancer'

Excessive levels of stress can result in the formation of cancer, research has revealed.

A study from Yale University has found that high levels of stress send signals to the body which can cause cells to develop into tumours.

Led by Tian Xu, the study looked at the genes in fruit flies in order to monitor the formation and mutation of certain genes which result in cancer.

It was discovered that a signalling process which is activated by "environmental stress conditions" increased the likelihood of cells developing the disease.

Professor Xu said: "A lot of different conditions can trigger stress signalling: physical stress, emotional stress, infections, inflammation – all these things. Another bad news for cancer."

The scientist added that the discovery would be helpful in treating cancer in the future.
