Heart drugs found not to cause increase in cancer risk

A meta-analysis of data has refuted an earlier claim linking drugs for reducing heart problems with an increase in cancer risk. The review claims to be based on better data from a larger number of people using the class of drugs whose safety had been called into question. The previous study was criticized for using data from short-term clinical trials, which researchers say would not be able to find a true link with cancer because of the delay in developing it after exposure to carcinogenic substances.
