having a bowel movement less than three times a week, can be your body’s way of suggesting that you make some minor adjustments in diet or exercise.
However, constipation can also be a symptom of a colon cancer. In the beginning of the colon, waste material is slushy and can easily maneuver around anything that gets in its way.
But as it nears the end of the colon, stool solidifies and is less forgiving of obstacles. A tumor in the rectum or far end of the colon can make it very difficult for waste to get by, thereby causing constipation.
changes in bowel habits which include diarrhea for more than a couple of weeks may be a symptom of colon cancer and should be followed up with a visit to your family doctor. Make a conscious effort to know your bowel habits so you can recognize any changes.
