Exercise Boosts Colon Cancer Survival: Study Highlights Life-Saving Impact of Physical Activity
April 7, 2025
Ongoing research aims to further understand the biological mechanisms that link exercise to improved health outcomes, particularly its positive effects on immune function and inflammation.
Kathryn Schmitz, an exercise oncology researcher, stresses that regular physical activity is one of the most effective strategies within a patient's control to reduce mortality from colon cancer.
Meyerhardt emphasizes that any physical activity is better than inactivity, reinforcing the importance of movement for cancer survivors.
Survivors who engaged in regular exercise, such as walking for about an hour at a moderate pace six days a week, demonstrated better overall survival rates compared to less active individuals.
Dr. Jeff Meyerhardt, co-director of the Colon and Rectal Cancer Center at Dana-Farber Cancer Institute, asserts that any level of physical activity is beneficial for cancer survivors, highlighting that even small amounts of exercise can make a difference.
Research indicates that physical activity induces beneficial chemical reactions in the body, improving immune function and reducing inflammation, both of which are crucial in cancer management.
A recent study surveyed nearly 3,000 colon cancer patients about their exercise habits before and after treatment, revealing that regular physical activity significantly enhances survival rates.
The American Cancer Society recommends at least 150 minutes of moderate-intensity physical activity each week to lower cancer risk, noting that any increase in activity is advantageous.
Despite declining overall death rates from colon cancer due to advancements in screening and treatment, survivors still face a higher mortality risk compared to the general population, primarily due to recurrence concerns.
Starting exercise early in life is vital for reducing future colorectal cancer risk, as highlighted by Dr. Ng.
Dr. Kimmie Ng emphasizes the rising rates of colon cancer among individuals under 50 and advocates for exercise as a protective measure against both the development and recurrence of colorectal cancer.
Survivors who were more active had significantly better overall survival rates, even when compared to the general population.
