We'll also be able to look at different types of questions over the life of the study. So early on, we may be able to better describe the environments that women are contending with that may influence their cancer. Midway through the study, we may get at those early questions about why more aggressive cancers. And then we imagine that after a decade or so, we can start to think about survivorship and mortality from cancer.
