Myth: Drinking from plastic water bottles causes breast cancer.

No. Using disposable plastic water bottles does not increase a person’s cancer risk. However, reusing plastic water bottles can potentially cause sickness (vomiting or diarrhea) because of germ growth – but not cancer.
While it’s important that we all exercise caution and monitor our exposure to toxins and known carcinogens in our environment it’s also important that we keep complicated information/issues from being misinterpreted and spread as frightening rumours.
Some worry that DEHA, a well-known plasticizer used to make plastics less brittle, can leak out of the plastic into water. However, according to the Canadian Cancer Society, there is no proof that DEHA is cancerous (to see their full article, click HERE).
