Timing of cancer radiation therapy may minimize hair loss, researchers say
Discovering that mouse hair has a circadian clock — a 24-hour cycle of growth followed by restorative repair — researchers suspect that hair loss in humans from toxic cancer radiotherapy and chemotherapy might be minimized if these treatments are given late in the day.
The study, which appeared May 20 in the online edition of the Proceedings of the National Academy of Sciences, found that mice lost 85 percent of their hair if they received radiation therapy in the morning, compared to a 17 percent loss when treatment occurred in the evening. … Read More »
