Statistics for colorectal, or colon, cancer show that the men are more likely than women to be diagnosed with the disease, and those of an African descent have a higher risk than other populations. Approximately 90% of cases occur after the age of 50, which suggests that other risk factors combine over time to create the conditions that cause this cancer. Colon cancer is the second leading killer among the many other types of cancer, primarily due to insufficient screening and poor lifestyle choices. Though several risk factors are not controllable, experts agree that a great many cases of colon cancer can be prevented.Exercise Eliminates Several Risk FactorsWhether you fall into a risk group, have been diagnosed, or are currently undergoing treatment, the leading cancer research organizations agree it is important to establish a physical fitness program and stick to it. Exercise is an important part of any prevention plan, as it counteracts the sedentary lifestyle and obesity that lead to increased risk. Though the emphasis should be on aerobic exercise most days of the week, anaerobic training can also play a role in leading to a more healthy body composition and self-image.What About Exercise during Treatment?For those undergoing treatment, it often becomes difficult to tell the difference between symptoms of the cancer and symptoms of treatment. Fatigue is the most common complaint, followed by digestive irregularity. Exercise can help relieve these symptoms and improve the quality of life, according to research. Patient safety must be accounted for though, and it is best to form an exercise plan with the aid of a physical therapist working in tandem with the cancer treatment team. A growing number of cancer clinics and insurance plans are including professionally trained fitness experts on the basis of current research.Diet is the other major change to reduce risk of colon cancer. Epidemiological studies show that those eating a high-fat, low-fiber diet are at increased risk. Eating enough vegetables and whole grains will provide all the dietary fiber needed to maintain regular digestion, as well as all the micro-nutrients necessary for strong immune function.
