Stress and cancer 'not clearly linked'

Despite a number of studies, there is no clear link between stress levels and cancer.

This is the view of Martin Ledwick, head information nurse at Cancer Research UK.

Following a recent study into the effects of a more positive environment on mice, Mr Ledwick said: "Over the years, studies in humans that have looked at stress and cancer development or survival have shown conflicting results and there is no clear evidence one way or the other about its relationship to cancer."

The study, which was published in Cell, revealed that mice with an enriched environment had a decreased level of cancer growth.

However, Mr Ledwick claimed that it was not possible to link this conclusion to humans.

Although he did add: "From a quality of life perspective, we would strongly support cancer patients having access to emotional support to help them get through the experience of having cancer."
