i heard thats how sheryl crow got breast cancer. i also heard that reusable bottles with the number 7 printed on the bottom should be thrown away. most people i've asked said this wasn't true. what do you think?

I have heard that plastic in general can cause cancer...

My teacher is a radiation therapist and she doesn't use plastic at all, no saran wrap, water bottles or even plastic tumbler cups...

It is the chemicals in them

what i heard was that you should not drink water that has been left in a bottle in the car when its hot. they say that something in the plastic and heat will effect the water. But i don't believe that because all these company's have this water stored in warehouses that are hot and then the delivery trucks do not keep these items cold. Ive also heard that all water contains a type of poison that keeps the water from going bad after it is bottled. They say that all of this causes cancer.
