Researchers never expected to win the war against cancer with a single decisive blow. But thanks to a growing number of small but important advances, medicine has been gaining ground. The latest evidence comes in a report just published in the Journal of the National Cancer Institute.

Yong Zhu, PhD, is assistant professor in the Department of Epidemiology and Public Health at Yale University School of Medicine, where he has been investigating circadian rhythms and cancer risk. In a recent article in the journal Medical Hypotheses, he proposed a provocative idea: that non-Hodgkin’s lymphoma could be linked to disruptions of circadian rhythm. PDQhealth asked him to explain.
