Good for you. Many of us have also survived cancer, and view the entire BPA scare tactics as a hoax. Even if the risks were worth worrying about, they involve passing harmful chromosonal mutations to your offspring. Since I'm well past child rearing years, I couldn't care less.
When Nalgene switched to BPA free bottles, I quickly bought a lifetime supply of BPA enriched bottles, in case the new ones were substandard. I'm still using them.
