Insomnia in Young Adults Linked to Rising Early-Onset Cancer Risk
Two MD Anderson-led studies of more than 18 million US adults aged 18–50 found that poor sleep patterns are linked to higher risk of early-onset cancers (bowel, breast, uterine, ovarian), with insomnia associated with up to a threefold increase in cancer risk within five years. While the findings suggest sleep disruption could be a modifiable risk factor, experts caution that association does not prove causation and more research is needed to account for lifestyle factors and other confounders. Globally, cases and deaths from cancer in under-50s have risen over recent decades.
