Structured exercise linked to longer cancer survival and time free of disease

Recent research suggests structured exercise may contribute to longer cancer survival and reduced time free of disease, according to a meta-analysis published in the British Journal of Sports Medicine. This synthesis of evidence from 21 randomized controlled trials involving 8,449 participants with various types of cancer (with a focus on breast, bowel, and pancreatic cancers) demonstrated that structured exercise was associated with a 23% lower risk of death and a 17% lower risk of recurrence before death compared to non-exercisers.

The benefits appeared strongest in early-stage disease and for those who adhered to the exercise program at least 70%. Aerobic exercise and combined aerobic-strength training programs showed the most promising effects, while strength training alone did not demonstrate a clear benefit. Although the researchers acknowledge limitations, such as variations in exercise types and limited evidence for advanced-stage cancers, they conclude that clinicians can reasonably recommend structured exercise as part of oncological care, recognizing that ongoing trials will continue to refine its optimal application.
