Wild berries native to North America may have a role in boosting cancer therapy, according to a study in the Journal of Clinical Pathology.

But the UK research is at an early stage, with experiments carried out only on cancer cells in laboratories.
Cancer Research UK says much more work is needed to test the effectiveness of berries, particularly in human trials, BBC informs.
