LONDON (AP) - New research suggests that some of the world's most popular blood pressure pills may slightly increase the risk of getting cancer, but doctors say it's too soon to ditch the drugs.
      
In an analysis of five previous studies, medical experts found a link between people taking medicines known as ARBs and cancer. The drugs are taken by millions of people worldwide.
      
Researchers found that people who took the drugs had about a 1 percent higher risk of getting cancer than people who weren't on the drugs. But there was no difference in the rate of cancer deaths.
      
The study's lead author calls the risk for the individual patient "modest."
      
The study is published Monday in the medical journal, Lancet Oncology.
