Can regular exercise help lower the risk of colon cancer? Researchers explore

The research is mounting on the benefits of exercise for different types of cancer.

Exercise has been shown to lower the risk of a range of chronic conditions, from diabetes to heart disease and autoimmune disease. The research is mounting, providing us with more reasons to get our muscles moving. I know from my own personal experience that exercise helps simmer down symptoms of my autoimmune bone condition called ankylosing spondylitis. It makes sense because not only is movement natural and beneficial, it’s been shown to lower inflammation, and ankylosing spondylitis is an inflammatory chronic condition.

So, what about cancer? Previous research reveals that exercise can lower the risk of breast, colon, and prostate cancer. Recently, researchers investigated whether regular exercise could benefit colon cancer patients who adhered to a routine for several years. Let’s delve into the research.

The study

In a study published in JAMA Oncology, cancer patients increased their weekly exercise levels with the help of coaches and stuck to a specific routine for several years. The researchers followed each participant for eight years. The study involved 900 patients in six countries with an average age of 61. Around 90% of the patients had stage 3 colon cancer. Following chemotherapy and surgery, half of the patients participated in an exercise program, while the other half (the control group) received a booklet encouraging proper nutrition and physical activity to aid in recovery.

The goal was for the participants to increase their exercise by a specific amount every week. For the first year, they met with a kinesiologist, physical therapist, or personal trainer every two weeks for a supervised, customized workout tailored to their preferences and lifestyle. Following that first year, participants met up with their coaches monthly for two years.

The researchers had two primary questions in mind: Would exercise lower the risk of cancer returning? Would being assigned an exercise coach prompt people to work out more after finishing their cancer treatments? Within five years following treatment for stage 3 colon cancer, the condition returns in about 35% of people. 

The results

The researchers revealed the following:

  • Those who stuck to an exercise program following chemotherapy and surgery for high-risk Stage 2 colon cancer or Stage 3 colon cancer could lower the risk of cancer recurring by 28%.
  • Following an exercise program post-treatment could also lower the risk of a new cancer diagnosis or fatality by 28%.
  • After those eight years, 90% of those in the exercise program hadn’t had any new cancer diagnoses or cancer recurrences. However, this number was 83% for the control group. 
  • Those who exercised more also had lower risks of other cancers, including breast cancer.
  • Those who didn’t take part in the exercise program also got fewer hours of weekly exercise, showing that working with a coach really did result in more hours spent moving those muscles.

The takeaway

These results align with previous research on the benefits of exercise for cancer, so much so that the researchers stated that exercise should be part of the standard treatment for colon cancer. Studies conclude that regular exercise can reduce the risk of colon, breast, and rectal cancer recurrence by as much as a surprising 45%. Researchers have highlighted the impact of exercise on insulin levels, metabolic rate, and body composition.

The study also shows us that having a coach could really encourage you to work out for more hours than you would on your own.

Here’s what the growing research shows about Parkinson’s disease and exercise
Are dancing and aerobic exercise beneficial for those with Parkinsons?

As someone with an Autoimmune bone disease, I know how exercise and moving my body helps with pain, stiffness, and other symptoms. Depending on the day, I gravitate toward different types of exercise, from jogging to yoga and bodyweight moves. Mounting research highlights how being physically active can improve symptoms and lower the risk of a range of chronic conditions. I wasn’t surprised to see that studies reveal exercises like running, yoga, and stretching are beneficial for ankylosing spondylitis, which is my autoimmune condition that primarily affects the bones.

Parkinson’s disease is a movement disorder involving a decline in dopamine production in the brain. Dopamine is a neurotransmitter that plays a role in coordinating movement, and people with Parkinson’s have several related symptoms, including stiffness, tremors, and issues with balance. Growing research also unveils the benefits of physical activity for those with Parkinson’s disease, including improving daily symptoms. Let’s explore.

Research shows walking can lower blood pressure and the symptoms of depression, but what about the risk of cancer?

When I’m not sitting at my computer, I’m trying to stretch my legs and get my muscles moving and my blood circulating. Researchers associated a sedentary lifestyle with a higher risk of cancer, cardiovascular disease, and metabolic diseases. Recently, I’ve covered the growing research on the benefits of exercise and on walking, which is natural, simple, accessible, and good for your body. 

For example, one study revealed that maintaining a brisk walking pace lowers your risk of developing dementia later in life. Walking can also improve your blood sugar, and just a 10-minute walk around the block can lower blood pressure and perk up your mood. Previous research has shown that physical activity can lower the risk of cancer, and a new study from the University of Oxford further explored this association. Does walking really lower your risk of cancer? Does more steps mean an even lower risk? Let’s look at the study.

Does building muscle help protect your brain from dementia? Interesting study
Can working out keep your brain sharp throughout the years?

Protecting our brains helps us stay sharper later in life so we can continue to do the cognitive tasks and activities we love. Some days, I feel like my brain is working better than other days, and lots of factors tend to come into it, such as how well I slept and how I’ve been eating. One factor that plays a role is exercise. I’m impressed by much of the research so far, which shows us how regular exercise is beneficial for our brains and boosts BDNF. Brain-derived neurotrophic factor (BDNF) is a protein that aids in the survival and growth of neurons and allows your brain to change and adapt over time, which is crucial for learning and memory.

Recently, researchers wanted to know whether working out and building muscle are protective against the risk of dementia. Are you at a higher risk of dementia if you have muscle loss over the years? Let’s take a look at the research.
