You are right about the cancer I do not know of ozone causing cancer. All I know is it's highly reactive and can cause changes in DNA. It is purely an assumption on my part that ozone can cause cancer due to the fact that many forms of cancer are caused by odd DNA sequencing. I have not researched it at all other than remembering bits and pieces from class and putting it together. I do not know of any formal studies but I'm sure there are some out there.

You must understand that I have huge phobia of cancer and most diseases for that matter. I try to live a healthy life and take great lengths to achieve this. I would rather be safe now than sorry later.

Thanks, David
