* Two years use of Actos doubles risk of bladder cancer
* Absolute risk still low, study finds
LONDON May 31 (Reuters) - Taking Takeda Pharmaceutical's diabetes drug Actos for more than two years doubles the risk of bladder cancer, although in absolute terms the risk is still low, researchers said on Thursday.
A study by Canadian researchers, published online by the British Medical Journal, quantified the risk by analysing the records of more than 115,000 British patients newly treated with diabetes drugs between 1988 and 2009.
They found that Actos use of two years or more was associated with 88 extra cases of bladder cancer per 100,000 person years. This rose to 137 extra cases among patients who had taken more than 28,000 milligrams of the drug.
