Scented Candles as an Unrecognized Factor that Increases the Risk of Bladder Cancer; Is There Enough Evidence to Raise a Red Flag?

The causes of bladder cancer are not yet fully uncovered, however the research has identified a number of factors that may increase the risk of developing this cancer. The chemical carcinogenesis of bladder cancer due to chronic exposure to aromatic hydrocarbons has been well-established. The identification of this correlation led to an improvement of safety measures in chemical industry and a gradual decrease of bladder cancer cases among workers. Nevertheless, in the majority of bladder cancer cases, the specific cause of the disease still can't be specified. It makes the question of unrecognized factors associated with bladder cancer development even more relevant. Taking under consideration known chemical carcinogenesis of bladder cancer, this minireview takes under investigation the possible link between using scented candles and a risk of bladder cancer development. Burning scented candles contain many of the substances that are associated with a bladder cancer. Furthermore the scented candles are not only very popular but also widely available on the market, with limited quality regulations and unspecified raw materials determining a spectrum of potentially dangerous substances emitted during burning.
