Your specific colon resection strategy will depend on many factors, including the following:
- The location of the tumor
- The presence of other cancers or polyps
- The stage of the cancer
- The risk of developing colon cancer in the future
- Your preferences

Signs and symptoms of colon cancer include: A persistent change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool. Rectal bleeding or blood in your stool. Persistent abdominal discomfort, such as cramps, gas or pain. A feeling that your bowel doesn’t empty completely.
What is the stage 1 colon cancer?
Stage 1 colon cancer indicates the cancer has grown into the inner layer of the colon, called the mucosa, to the next layer of the colon, called the submucosa. It hasn’t spread to the lymph nodes.
At later stages, symptoms tend to vary based on tumor size and location in your large intestine. These symptoms can include: change in bowel habits. blood in stool or rectal bleeding.
Primary tumor (T). Primary tumor refers to how large the original tumor is and whether cancer has grown into the wall of the colon or spread to nearby areas. Regional lymph nodes (N). Regional lymph nodes refer to whether cancer cells have spread to nearby lymph nodes.
Diagnostic tests performed may include imaging of the abdomen, liver, and chest with CT scans, X-rays, or MRI scans.
If after taking a FIT test or a sigmoidoscopy you test positive for colorectal cancer, your healthcare provider will suggest a colonoscopy to confirm your diagnosis. A colonoscopy is a screening test where the doctor uses a long, narrow tube with a small camera attached to view the inside of your colon.
Surgery is often the only treatment needed for stage 0 colon cancer. Stage 1. Surgery alone is recommended for stage 1 colon cancer.
4A stage. This stage indicates that cancer has spread to one distant site, such as the liver or lungs. 4B stage. This most advanced stage of colon cancer indicates cancer has spread to two or more distant sites, such as the lungs and liver.
How many stages of colon cancer are there?
Share Your Story. The stages of colon cancer refer to the extent of spread of the cancer at the time that it is identified. There are 4 main stages of colon cancer, referred to as stages 1-4. Stage 1 colon cancer has spread from the lining of the large intestine into the muscular wall of the large intestine.
When signs and symptoms do occur, the following are some of the most typical signs of colon cancer: A persistent change in bowel habits. Narrow or pencil-thin stools. Diarrhea or constipation. Blood in the stool, rectal bleeding (blood may appear as bright red blood or dark stools)
Stage 3 colon cancer has spread to lymph nodes in the area or to other organs in the area. Stage 4 colon cancer is metastatic colon cancer. It has spread away from the colon to other parts of the body such as the liver, bones, or lungs. The term Stage 0 is sometimes used for a very early cancer that only affects the lining of the intestine.
Colon cancer (bowel cancer) is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.
A colonoscopy is a diagnostic procedure to evaluate the health of the colon and rectum. A colonoscopy is done with a colonoscope, a tube with a camera and surgical tools. The doctor can view the the colon, sample tissue for biopsy, or remove polyps.
Colorectal cancer (colon cancer) is the cause of many cancer deaths. Learn about the warning signs, symptoms, screening process, stages, and treatment related to colorectal cancer.
Colon cancer is a type of cancer that begins in the cells lining the large intestine (colon); some researchers include the rectum and prefer the term colorectal cancer. There are over 101,000 new cases of colon cancer every year in the U.S. Colon cancer is the third-leading cause of cancer death in the U.S. for both men and women.
What are the symptoms of colon cancer?
Certain basic colon cancer symptoms might include hemorrhoids, inflammatory bowel disease, infection, etc., so patients should consult their physician if they experience any of the following symptoms.
Symptoms Include: Change in occurrence of bowel movements. Bloody stools. Even after emptying bowels, feeling as though it is incomplete. Stomach cramps. Fatigue. The treatment here is surgery to remove the section of the colon which has cancer besides the lymph nodes associated with it.
Also if you notice any change in color in stools then you have to inform the doctor. Another change in bowel habits that may indicate colon cancer is having narrower than normal stools or other changes in the appearance of your stool.
In terms of colon cancer anemia may be caused by a microscopic amount of chronic blood loss in the stool. In such case, the total body stores of iron are depleted as iron is lost with the red blood cells. The production of new red blood cells is reduced and eventually lowers the total red blood cell count causing anemia.
Radiation therapy is used for advanced cancer to alleviate the symptoms. Overall, it is very important to know about the colon cancer symptomsto rule out any serious conditions.
Stage I comprises cancers which are part of a polyp. If the polyp is detached totally during colonos copy, by not leaving any cancer cells at the margins or edges of the detached sample then no other treatment is required.
In stage IV colon cancer, cancer will spread to all the distant organs and tissues through the colon. The first place to spread is to the liver and then slowly it can expand to other body parts like lungs, peritoneum, brain and other far lymph nodes.
How do you know if you have colon cancer?
Signs and symptoms of colon cancer include: A persistent change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool. Rectal bleeding or blood in your stool. Persistent abdominal discomfort, such as cramps, gas or pain. A feeling that your bowel doesn’t empty completely.
A feeling that your bowel doesn’t empty completely. Weakness or fatigue. Unexplained weight loss. Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they’ll likely vary, depending on the cancer’s size and location in your large intestine.
The colon is the final part of the digestive tract. Colon cancer typically affects older adults, though it can happen at any age. It usually begins as small, noncancerous (benign) clumps of cells called polyps that form on the inside of the colon. Over time some of these polyps can become colon cancers.
The most common inherited syndromes that increase colon cancer risk are familial adenomatous polyposis (FAP) and Lynch syndrome , which is also known as hereditary nonpolyposis colorectal cancer (HNPCC). Family history of colon cancer.
Risk factors. Factors that may increase your risk of colon cancer include: Older age. Colon cancer can be diagnosed at any age, but a majority of people with colon cancer are older than 50. The rates of colon cancer in people younger than 50 have been increasing, but doctors aren’t sure why. African-American race.
Take steps to: Eat a variety of fruits, vegetables and whole grains. Fruits, vegetables and whole grains contain vitamins, minerals, fiber and antioxidants, which may play a role in cancer prevention.
For instance, some evidence links a reduced risk of polyps and colon cancer to regular use of aspirin or aspirin-like drugs.
