Thanks very much for the question.
It's a difficult answer to a lot of questions around the rising rates of cancer and other diseases, in that we often don't know. That's particularly the reason why we have sessions like this, where we talk about the need for information. When we have such a large number of substances that have been grandfathered and are on the market without any data or evidence of either their safety or their harm, we simply can't answer the question as to whether those substances are part of the problem or not.
We know there's a problem. The problem is unexplained. We know there are all these chemicals we have very little information about, and we need to be able to put those two things together.
