Blood pressure pills taken by millions worldwide could raise the risk of lung cancer, research has found.
It showed that patients on ACE inhibitors were 14 per cent more likely to develop the cancer than those on other types of drugs.
The risk went up the longer patients were on the medication. Those taking them for five years were 22 per cent more likely to get lung cancer rising to 31 per cent if they were on them for ten years.
Scientists believe the drugs cause the accumulation of chemicals called bradykinin on the lung which in turn leads to cancer.
