Why Losing Muscle With Age May Raise Your Cancer Risk
Based on: Sarcopenia promotes tumorigenesis by disrupting NOTCH-SDC2-regulated biogenesis of muscle-derived extracellular vesicles.
Healthy muscle releases tiny packets called extracellular vesicles that actually suppress tumor growth. As muscle shrinks with age (sarcopenia), it sends out fewer of these protective packets. In flies and mice, this helped tumors grow more easily. Exercise reactivated the pathway that produces these anti-tumor vesicles.
Key Insight
This study suggests maintaining muscle through exercise may support the body's natural anti-tumor signaling.

Staying Active From Midlife Cuts Sarcopenia Risk by Up to 78%
In Norwegians tracked for over 30 years, those who stayed active from middle age into their 70s had 78% lower odds of confirmed muscle loss. Even people who started exercising later in life saw meaningful benefits. People who became inactive lost most of the protection.
Low Vitamin D Linked to Muscle Loss, Especially in People With Diabetes
In a study of over 7,500 older adults, low vitamin D was tied to higher odds of sarcopenia (age-related muscle loss). The link was stronger in those with diabetes. In aged diabetic rats, vitamin D3 supplements improved muscle strength and reduced fat buildup inside muscle fibers.
Two Hours of Weekly Strength Training Hits the Sweet Spot for Longevity
In nearly 150,000 adults tracked for up to 30 years, doing 90 to 119 minutes of strength training per week was linked to a 13% lower risk of dying from any cause. More than two hours weekly added no extra benefit. Combining strength work with aerobic exercise gave the biggest mortality drop.
