Despite steady progress in reducing overall cancer mortality rates, cancer incidence in women is rising, according to the American Cancer Society’s “Cancer Statistics, 2025” report. Incidence rates in women 50-64 years of age have surpassed those in men, and rates in women under 50 are now 82% higher than their male counterparts, up from 51% higher in 2002. In 2021, for the first time, lung cancer incidence was higher in women under 65 than in men.
On Feb. 2, Nature Medicine published the results of a large, randomized, prospective clinical trial in the nascent and some say, fringe, field of chrono-oncology—the study of how natural biological rhythms might impact cancer outcomes.
