Poor sleep linked to rising cancer risk in under-50s
Recent research indicates that poor sleep patterns may contribute to the rising incidence of early-onset cancers among individuals under 50. Studies show that the number of younger people diagnosed with cancer has increased significantly over the past three decades. Experts emphasize the need for further investigation to understand the relationship between sleep disruption and cancer risk.
