Studies on the link between infrequent defecation and colon cancer are inconclusive. Chronic constipation may contribute to colorectal cancer by increasing the absorption of toxins. However, it is undetermined whether constipation or other factors common among sufferers of the condition cause any potential link. Family history, diet, dehydration, age, and general health are important factors in determining the risk of developing colon cancer.
Studies attempting to link infrequent defecation and colon cancer have so far been inconclusive. Some have shown a significant risk of colorectal cancer in those with frequent or prolonged constipation, while others have indicated that those who defecate more often may be at greater risk. More studies are needed to determine if there is indeed a link or pattern between infrequent defecation and colon cancer.
The leading theory of those who believe that chronic constipation contributes to colorectal cancers is that increased waste transit time results in more toxins being absorbed by the colon. These toxins can include carcinogenic materials that come from pesticides on foods, additives in synthetically produced foods, and other sources. Since fecal matter is located in the colon, water is absorbed by it and eventually the waste materials can also be reabsorbed into the body to be reprocessed by the liver and colon. Whether or not these theories are accurate is still undetermined, although some studies have shown that those who have frequent bouts of constipation may have an increased risk of colon cancer.
It is also undetermined whether any potential link between infrequent defecation and colon cancer would be caused by constipation itself or by other factors common among sufferers of the condition. Those battling colon cancer, especially those with no family history, are more likely to eat processed foods, be overweight, and not drink enough water. Fiber, which prevents constipation and keeps the colon moving smoothly, has been shown to reduce colorectal cancer risks in those who consume it regularly.
There have been additional studies showing opposite results to those mentioned above. They indicate that those who occasionally experienced constipation had a lower incidence of colon cancer risk than those who defecated two or more times a day. Further tests showed no link between defecation and cancer risk.
Several factors must be taken into consideration when determining your risk of developing colon cancer. Family history plays an important role, as the condition is often hereditary. Eating a diet high in fat and heavily processed foods also increases your risk, as does dehydration. These factors combined with your age and general health can have a big impact on your risk of developing cancer of any type.
