Colon Cancer Signs and Symptoms
Colon cancer often starts with no symptoms. The exact cause of most colon cancers is not known, however research says that approximately 75% of colorectal cancers occur in people with no known risk factors.
Risk factors that may increase a person’s risk of developing colon cancer include:
A family history of colon or rectal polyps or colorectal cancer, or Inflammatory Bowel Disease (Ulcerative Colitis or Crohn’s Disease) Genetic syndromes.
Colon cancer develops with few, if any, symptoms at first. If symptoms are present, they may include:
Blood in or on the stool
A change in bowel habits
Stools that are narrower than usual
General, unexplained stomach discomfort
Frequent gas, pains, or indigestion
Unexplained weight loss
These symptoms can also be associated with other health conditions. If you have any of the symptoms, discuss them with your health care provider. Only your health care provider, through testing, can determine why you’re having these symptoms.
