Just 10 minutes of vigorous daily exercise could significantly reduce the risk of bowel cancer and even slow its growth, new research from Newcastle University suggests. The groundbreaking study, published in the International Journal of Cancer, reveals that short bursts of high-intensity physical activity trigger rapid molecular changes in the bloodstream that actively combat cancer cells.This discovery offers new hope for preventing one of the leading causes of cancer-related deaths globally.[financialexpress+3]
How Short Workouts Fight Cancer
Researchers at Newcastle University, led by Dr. Sam Orange, found that intense exercise sparks a powerful biological response in the body. The study involved 30 overweight or obese, but otherwise healthy, volunteers aged between 50 and 78 years.Participants completed a single 10 to 12-minute high-intensity cycling session.Scientists then collected blood samples before and after the exercise.[daijiworld+10]
Analysis of these blood samples showed that exercise increased the concentration of 13 specific proteins in the serum.These proteins are crucial for reducing inflammation, improving blood vessel function, and boosting metabolism.When these exercise-induced molecules were applied to bowel cancer cells in laboratory conditions, they dramatically altered the activity of 1,364 genes.These genes play vital roles in DNA repair, energy production, and the regulation of cancer cell growth.[financialexpress+16]
Dr. Sam Orange, a Senior Lecturer in Clinical Exercise Physiology at Newcastle University, explained that these findings suggest exercise does not just benefit healthy tissues. He said exercise sends powerful signals through the bloodstream that directly influence thousands of genes in cancer cells."These results suggest that exercise doesn't just benefit healthy tissues, it may also create a more hostile environment for cancer cells to grow," Dr. Orange said.Even a single workout can make a difference.[outlookindia+6]
Bowel Cancer: A Growing Concern
Bowel cancer, also known as colorectal cancer, is a significant health challenge. It develops in the large bowel, which includes the colon and rectum.Cases of bowel cancer are on the rise, particularly among younger adults.Experts link this trend to inactive lifestyles and Western diets, which are often low in fiber and high in fat.Old age or a personal history of colon cancer can increase the risk, but lifestyle factors play a crucial role in prevention.[financialexpress+3]
Physical inactivity is a key factor contributing to bowel cancer in younger populations.The new study reinforces existing evidence that movement and exercise help halt bowel cancer growth.Previous research has already shown that regular exercise lowers the risk of developing colon cancer and can help survivors live longer and healthier lives.This latest study provides a deeper understanding of the molecular "why" behind these protective effects.[financialexpress+3]
Broader Health Guidelines and Future Hope
While this study highlights the impact of short, intense workouts, broader health guidelines also emphasize the importance of regular physical activity for overall cancer prevention. The American Cancer Society recommends that adults get 150 to 300 minutes of moderate-intensity activity or 75 to 150 minutes of vigorous-intensity activity each week.Achieving or exceeding the upper limit of 300 minutes is considered ideal.These guidelines also advise limiting sedentary behavior, such as prolonged sitting or screen time.[cancer+5]
This new research from Newcastle University adds to the growing body of evidence that even brief, high-intensity exercise sessions contribute significantly to health. It reinforces the idea that every bit of physical activity counts.The findings could lead to new avenues for cancer treatment. Researchers hope these insights might help develop therapies that mimic or enhance the biological effects of exercise.Such treatments could potentially improve cancer outcomes by influencing how cells repair damaged DNA and use fuel for energy.[daijiworld+3]
The study underscores the profound impact of physical activity on the body's internal environment. By making the body less conducive for cancer cell growth, even small, consistent efforts can offer powerful protection. This offers a compelling reason for everyone to incorporate more movement into their daily routines.
