Tupperware vs. other plastics

I recently heard the comment that all plastics cause cancer. That's a pretty bold statement, but worth investigating. Scare tactics are often used as marketing ploys and thus I try to find reliable sources and base my decisions on their recommendations with an added bit of common sense. The following links proved valuable in my search:

Cancer Society's view on Microwave and Plastics
Health Canada's view on Microwave and Plastics

BPA Free Tupperware Guarantee
Good Housekeeping on BPA Plastics

Always check to see that the product you're using is microwave and dishwasher safe! 

Check your plastics!
