Understanding the Link Between Exercise and Colorectal Cancer 

Colorectal cancer is a global health concern, affecting millions of people worldwide. In the United States, it is the third most diagnosed cancer in both men and women. Over the years, researchers have found a strong connection between physical activity and disease prevention. It has been proven time and again that staying physically active not only improves our fitness levels but also helps in reducing the risk of various diseases, including cancer.    

In this blog post, we will share detailed insights into the relationship between colorectal cancer and exercise, examining how it can play a crucial role in prevention, treatment, and ultimately, a better prognosis. Read on for more.   

What is Colorectal Cancer?

Often referred to as bowel cancer, colorectal cancer originates in the colon or rectum, which are integral parts of the digestive system. It occurs when the normal cells lining the colon or rectum undergo mutations, causing the cells to grow uncontrollably and eventually forming a mass of tissue known as a tumor. If left undiagnosed and untreated, these tumors can metastasize, invading nearby tissues and spreading to other body parts.   

Risk Factors for Colorectal Cancer

A combination of genetic, environmental, and lifestyle factors can increase the risk of colorectal cancer. One of the primary risk factors is age, with most cases diagnosed in individuals aged 50 and older. However, younger individuals can also develop colorectal cancer.   

Additionally, there are a few other risk factors which are as follows:  

• Family history of colorectal cancer and certain genetic conditions like Lynch syndrome or familial adenomatous polyposis (FAP)  

• History of colorectal cancer and certain types of colon polyps  

• A diet high in red and processed meats, low in fiber, fruits, and vegetables   

• Sedentary lifestyles  

• Obesity  

• Inflammatory Bowel Diseases (IBD) like ulcerative colitis and Crohn's disease   

• Smoking and excessive alcohol consumption   

• Type 2 diabetes   

• Radiation exposure in the abdominal or pelvic area  

Understanding these causes and risk factors is crucial in raising awareness about colorectal cancer and promoting early detection. Consult a healthcare provider and follow preventive measures to minimize the risk of colorectal cancer.   

4 Ways Exercise Can Reduce the Risk of Colorectal Cancer

Exercise is known to have multiple benefits for our health, and these effects extend to colorectal cancer prevention as well. The following are a few ways through which exercise and physical activity can reduce the risk of colorectal cancer:  

1. Maintains a healthy weight

Obesity is one of the most common risk factors for colorectal cancer. Regular exercise can help burn extra calories, promote weight loss, and prevent the accumulation of excess body fat - all of which can reduce the risk of developing colorectal cancer.   

2. Prevents inflammation

Chronic inflammation has been linked to the development of various types of cancer, including colorectal cancer. Regular physical activity can control oxidative stress in the body and improve immune function by reducing systemic inflammation. As a result, it can significantly reduce the risk of any cancerous growth.   

3. Promotes gut health

Exercise has a positive impact on gut health as it promotes a healthy gut microbiome, which plays a crucial role in maintaining a balanced immune system and reducing inflammation. A healthy gut microbiota helps create a healthy digestive system that is less conducive to the development of colorectal cancer.  

4. Improves insulin sensitivity

Insulin resistance can promote the development of colorectal cancer. By increasing glucose uptake and promoting proper insulin function, exercise helps reduce insulin resistance and lower the risk of colorectal cancer.      

Moreover, physical activity not only targets specific risk factors associated with colorectal cancer but also has a broader impact on overall health and well-being. It can lower blood pressure, improve cardiovascular health, and enhance the body's ability to manage stress – all of which can promote overall well-being and reduce the risk of developing various chronic diseases.   

Exercise & Prognosis for Colorectal Cancer

Research has revealed a strong association between regular exercise and improved prognosis among those diagnosed with colorectal cancer. Engaging in physical activity following diagnosis and treatment has been linked to a lower risk of cancer recurrence.   

Chemotherapy and radiation therapy often produce a range of side effects, such as fatigue, nausea, and diminished muscle mass, which can significantly affect the quality of life. After treatment, individuals can practice gentle exercises tailored to their capabilities to mitigate these side effects, maintain muscle strength, and improve overall energy levels.   

In addition, the endorphins released during physical activity can help alleviate stress, anxiety, and depression. Individuals should always consult their healthcare team before starting an exercise regime post-treatment.  

Exercise Guidelines 

Individuals need to keep a few aspects in mind, whether they are exercising to prevent cancer or navigating the challenges of treatment. The following are a few practical strategies to get the most out of your exercise routine:  

• Start gradually with low-impact activities like walking, gentle stretching, or swimming. Gradually increase the duration and intensity of the exercises as the body adapts.   

• Set achievable goals, considering current fitness levels and any treatment-related considerations.   

• Incorporate a variety of aerobic exercises, strength training, and flexibility exercises to get the most effective result.   

• Consistency is the key when it comes to exercise. Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity per week, along with strength training on two or more days. Individuals should consult a healthcare provider to understand the duration and intensity of exercise according to their body’s acceptance levels.  

• Pay attention to how the body responds to exercise and consult a healthcare provider in case of pain, dizziness, or discomfort.   

• Drink adequate water, increase fluid intake, and allow the body sufficient rest and recovery time to prevent overexertion.   

Those who are undergoing treatment for colorectal cancer should engage in light exercises like walking or gentle yoga when they feel energetic. If they lack energy, it is important to prioritize rest while still incorporating some form of movement, even if it is just short walks.   

The Bottom Line

The connection between exercise and colorectal cancer is becoming increasingly evident through scientific research and studies. Incorporating exercise into our daily routines, along with a balanced diet and regular screenings, can contribute to a lower risk of developing colorectal cancer and promote overall health and well-being. According to the American Cancer Society, the mortality rate associated with colorectal cancer has shown a consistent decline among both men and women over the past few decades, mainly because of screening and other preventive measures. Therefore, it is crucial to consult a healthcare provider to take the required measures to prevent this disease.
