"Early Fitness Reduces Cancer Risk, Study Finds"

A large long-term study involving over 1 million male Swedish conscripts found that being fit earlier in life is associated with a reduced risk, in some cases up to 42%, of developing nine different types of cancer later in life. Good cardiorespiratory fitness, such as engaging in sustained aerobic exercises like running, cycling, and swimming, was linked to a lower risk of lung, liver, oesophageal, head and neck, stomach, pancreatic, bowel, and kidney cancers. However, higher cardiorespiratory fitness was associated with a heightened risk of prostate and skin cancers. The study highlights the importance of promoting interventions to increase cardiorespiratory fitness for reducing cancer risk.
