India, July 7 -- Regular exercise may help reduce cancer risk by restoring the protective functions of ageing muscles, according to a new study by scientists at Duke-NUS Medical School in Singapore.

Published in Nature Communications, the study found that ageing muscles release fewer extracellular vesicles-tiny particles that enable cells to communicate with one another. These vesicles also undergo age-related changes that weaken protective signals capable of suppressing tumour growth.

The effects of ageing muscles are particularly evident in sarcopenia, an age-related condition characterised by the loss of skeletal muscle mass and strength. In Singapore, nearly one in three adults aged 60 and above is affected by the condition, which r...
