Beyond heart benefits, intense exercise packs an even greater benefit. A recent study shows that just 10–12 minutes of high-intensity activity can slow the growth of colorectal cancer cells. Scientists explored the effects of exercise on colorectal cancer cells. While previous studies have demonstrated that exercise offers protective benefits against cancer, this research sought to deepen our understanding of the underlying molecular processes.
The likelihood of developing colorectal cancer increases as people get older, with added risks from genetic factors and habits like consuming high amounts of red meat. This remains one of the most common cancers in the United States, expected to affect over 150,000 people a year.
Early detection of colorectal cancer allows for simpler treatment, often just surgery to remove the tumor, while advanced cases typically involve surgery plus chemotherapy or radiation. Since prior studies have suggested exercise can be helpful for individuals with colorectal cancer, the researchers in this latest investigation aimed to better understand how these benefits take place at a biological level.
The study involved 30 healthy but overweight or obese adults between the ages of 50 to 78. Participants performed an intense cycling session lasting about 10 minutes, after which researchers analyzed their blood, which resulted in detection of changes in the activity of more than 1,300 genes. Genes involved in cellular energy production ramped up, while those associated with aggressive cancer cell growth were suppressed. They also identified a specific blood molecule that activates DNA repair pathways, indicating that even brief intense exercise can meaningfully impact key cellular mechanisms.
The findings suggest real potential, but they are far from definitive and call for further rigorous investigation. Future work should focus on prospective clinical trials to clarify whether short bursts of intense exercise can genuinely improve survival rates, recurrence risk, or other key measures for colon cancer patients.

As we age, it becomes harder to lose body fat without also losing valuable muscle. A new study suggests one type of exercise may offer the best of both worlds. Researchers found that while all forms of exercise helped healthy older adults reduce body fat, only high-intensity interval training (HIIT) preserved lean muscle mass.
We know that obesity can raise the risk of heart disease, type 2 diabetes and other health conditions. And, for years, BMI has been one of the most common ways to assess weight-related health risks. But for older adults, BMI may not provide the full picture. In a new study, an increased waist size was associated with an increased risk of premature death among adults 65 and older.Waist size is a simple way to estimate the amount of visceral fat a person may have.
Millions of people around the world start their day with a cup of coffee. In 2021 alone, approximately 10 billion tons of coffee were consumed globally. With consumption at such a high level, researchers are taking a closer look at how these beverages may affect health. A recent study suggests that how much coffee you drink may influence its benefits, adding to evidence that coffee may have several positive effects on eye health.
