Colon Cancer Signs

When colorectal cancer first develops, there may be no symptoms at all. But as the cancer grows, it can cause changes that people should watch for. Common signs and symptoms of colorectal cancer include:

    a change in the frequency of bowel movements
    diarrhea, constipation, or feeling that the bowel does not empty completely
    either bright red or very dark blood in the stool
    stools that are narrower than usual
    general abdominal discomfort such as frequent gas pains, bloating, fullness, and/or cramps
    weight loss with no known reason
    constant tiredness
    vomiting

These symptoms may be caused by colorectal cancer or by other conditions. It is important to check with a doctor if you have symptoms because only a doctor can make a diagnosis. Don't wait to feel pain. Early cancer usually doesn't cause pain.

Colon cancer facts

    Colorectal cancer is a malignant tumor arising from the inner wall of the large intestine.

    Colorectal cancer is the third leading cause of cancer in males and fourth in females in the U.S.

    Risk factors for colorectal cancer include heredity, colon polyps, and long-standing ulcerative colitis.

    Most colorectal cancers develop from polyps. Removal of colon polyps can prevent colorectal cancer.

    Colon polyps and early cancer can have no symptoms. Therefore regular screening is important.

    Diagnosis of colorectal cancer can be made by barium enema or by colonoscopy with biopsy confirmation of cancer tissue.

    Treatment of colorectal cancer depends on the location, size, and extent of cancer spread, as well as the health of the patient.
    Surgery is the most common treatment for colorectal cancer.

    Chemotherapy can extend life and improve quality of life for those living with colorectal cancer.

What is cancer of the colon and rectum?

The colon and the rectum are the final portions of the tube that extends from the mouth to the anus. Food enters the mouth where it is chewed and then swallowed. It then travels through the esophagus and into the stomach. In the stomach, the food is ground into smaller particles and then enters the small intestine in a carefully controlled manner. In the small intestine, final digestion of food and absorption of the nutrients contained in the food occurs. The food that is not digested and absorbed enters the large intestine or colon and finally the rectum. The large intestine is about six feet long and acts primarily as a storage facility for waste; however, additional water, salts, and some vitamins are further removed. In addition, some of the undigested food, for example, fiber, is digested by colonic bacteria and some of the products of digestion are absorbed from the colon and into the body. (It is estimated that 10% of the energy derived from food comes from these products of bacterial digestion in the colon.) The remaining undigested food, dying cells from the lining of the intestines, and large numbers of bacteria are stored in the colon and then periodically passed into the rectum. Their arrival into the rectum initiates a bowel movement that empties the colonic contents from the body as stool.

Most of the large intestine rests inside a cavity in the abdomen called the peritoneal cavity. Parts of the colon are able to move quite freely within the peritoneal cavity as the undigested food is passing through it. As the colon heads towards the rectum, it becomes fixed to the tissues behind the peritoneal cavity, an area called the retroperitoneum. The end portion of the large intestine, the part that resides in the retroperitoneum, is the rectum. Unlike much of the rest of the colon, the rectum is fixed in place by the tissues that surround it. Because of its location, treatment for rectal cancer often is different than treatment for cancer of the rest of the colon, as we'll explain later.
