In most cases, people who have these symptoms do not have cancer. Still, if you have any of these problems, it is a sign that you should go to the doctor so the cause can be found and treated, if needed:
- A change in bowel habits, such as diarrhea, constipation, or narrowing of the stool, that lasts for more than a few days
- A feeling that you need to have a bowel movement that is not relieved by doing so
- Rectal bleeding
- Dark stools, or blood in the stool
- Cramping or abdominal (belly) pain
- Weakness and fatigue
- Unintended weight loss
When colon cancer does turn out to be the cause, symptoms often appear only after the cancer has grown or spread. That’s why it’s best to be tested for colon cancer before ever having any symptoms. Colon cancer that’s found through screening – testing that’s done on people with no symptoms – is usually easier to treat. Screening can even prevent some colon cancers by finding and removing pre-cancerous growths called polyps.

There are number of symptoms that can signify colon cancer. Here are some common symptoms you should pay attention to—if you have a few of them, it’s highly recommended you see your doctor for a full screening.
- Narrower stool than usual
- Feeling like the bowel is not completely empty after a bowel movement
- Bright or dark red blood in stool
- Bleeding from the rectum
- Feeling full if you didn’t eat
- Pain or discomfort in the rectum
- Lump in the abdomen or rectum
- Shortness of breath
- Lost appetite
- Weight loss
- Bowel obstruction that causes pain in the lower abdomen
- A tear or hole in the intestine
- Frequent urinary tract infections
- Swollen lymph nodes
- Enlarged liver
- Buildup of fluid in the abdomen
- Pain in the abdomen, buttocks or legs
SCREENING COULD SAVE YOUR LIFE
Because colon cancer often doesn’t cause symptoms until it is advanced, the American Cancer Society recommends regular colon cancer screening for most people starting at age 50. People with a family history of the disease or who have certain other risk factors should talk with their doctor about beginning screening at a younger age. Several different tests can be used to screen for colon cancer. Talk with your doctor to find out which tests might be right for you.
When colon cancer is found early, before it has spread, the 5-year relative survival rate is 90%. This means 9 out of 10 people with early-stage cancer survive at least 5 years. But if the cancer has had a chance to spread outside the colon, survival rates are lower.
ASSOCIATION BETWEEN DIET
AND INCREASED COLON CANCER RISK
Studies of large groups of people have shown an association between a typical Western diet and an increased risk of colon cancer. A typical Western diet is high in fat and low in fiber.
When people move from areas where the typical diet is low in fat and high in fiber to areas where the typical Western diet is most common, the risk of colon cancer in these people increases significantly. It's not clear why this occurs, but researchers are studying whether a high-fat, low-fiber diet affects the microbes that live in the colon or causes underlying inflammation that may contribute to cancer risk. This is an area of active investigation and research is ongoing.
INHERITED GENE MUTATIONS
THAT INCREASE THE RISK OF COLON CANCER
Inherited gene mutations that increase the risk of colon cancer can be passed through families, but these inherited genes are linked to only a small percentage of colon cancers. Inherited gene mutations don't make cancer inevitable, but they can increase an individual's risk of cancer significantly.
The most common forms of inherited colon cancer syndromes are:
- Hereditary nonpolyposis colorectal cancer (HNPCC). HNPCC, also called Lynch syndrome, increases the risk of colon cancer and other cancers. People with HNPCC tend to develop colon cancer before age 50.
- Familial adenomatous polyposis (FAP). FAP is a rare disorder that causes you to develop thousands of polyps in the lining of your colon and rectum. People with untreated FAP have a greatly increased risk of developing colon cancer before age 40.
FAP, HNPCC and other, rarer inherited colon cancer syndromes can be detected through genetic testing. If you're concerned about your family's history of colon cancer, talk to your doctor about whether your family history suggests you have a risk of these conditions.
