I've heard that it's possible to get cancer from using plastic water bottles. Is this true?

It is possible, but the risk is very small. The main concern is exposure to chemicals in the plastic itself, such as bisphenol A (BPA). BPA can leach into the liquid inside the bottle and potentially cause health problems. However, most plastic bottles are lined with a chemical barrier that prevents any of these chemicals from getting into the liquid.
