She says she's glad that timing -- and body rhythms -- are emerging as very important characteristics to consider when physicians schedule screening, detection, and treatments. With this new research, she sees great promise in correlating body rhythms to therapy. "I can see that, eventually, higher circadian rhythms will help dictate daily patterns of rest and activity. I find that very exciting, and I hope the research in circadian rhythms continues."
