Colon cancer starts when a cell in the colon mutates and no longer follows the rules of how often it should divide. The cell begins to divide and grow, sometimes quickly. Polyps and tumors develop, and if they grow large enough, they are considered cancer. Sometimes weight loss occurs in conjunction with colon cancer.
Early Symptoms
Weight loss, accompanied by vomiting, constant fatigue, abdominal discomfort and narrow stools are the early signs of colon cancer, according to Inside "Colon Cancer--Part II" by Dr. Carlton Fraser (see Reference 3).
Cause
Polyps and colon cancer tumors quickly metabolize food and nutrients fed to the body. This causes the weight loss. Later, treatment can also cause weight loss because it lowers the desire for food and causes nausea.
Warning
Report unexplained weight loss of 10 pounds or more to a doctor, advises the American Cancer Society.
Prevention/Solution
Regular colon screenings help prevent the spread of colon cancer. Keeping weight in a normal range by eating fresh fruits and vegetables is also important, says Prof. Jonathan Rhodes, a gastroenterology consultant.
Treatment
Depending on the severity, colon cancer is treated with various combinations of chemotherapy, radiation and surgery.
