Does drinking warm bottled water increase the risk of breast cancer?

Drinking warm bottled water does not increase the risk of breast cancer.

Some people worry that warming (or freezing) plastic bottles or food containers releases a chemical called bisphenol A (BPA) which can interact with our hormones and cause breast cancer.

It’s true that if a plastic bottle or container is exposed to extremely high temperatures, chemicals such as BPA in the plastic are released into the water or food product inside. But the amount released would still be within safe limits and would not cause any harm.

Research has shown that, even when consumed at high levels, BPA is not a health concern.
