Overview
A Stage 3 Colon Cancer diagnosis is divided into three stages, Stage 3A, Stage 3B and Stage 3C. In all Stage 3 Colon Cancer Stages, the cancer has spread to nearby lymph nodes, but has not yet spread to any other parts of your body.

- Stage 3A Colon Cancer
- Stage 3B Colon Cancer
- Stage 3C Colon Cancer
Overview
Stage 3A Colon Cancer diagnosis is when:
A) The cancer has spread to the intermediate layers of your colon, called the Submucosa or Muscle layers and has affected 1-3 of your lymph nodes or nearby tissue as shown in the left image,
or
B) The cancer has only spread to the superficial layers of your colon called the mucosa and submucosa and has affected 4-6 lymph nodes as shown in the image on the right.
What Tests Will I Need and Why?
Blood and Imaging tests are done to understand your general health, confirm your diagnosis and determine your cancer stage.
A test, called a Colonoscopy, is usually the first step to see if there is a tumor inside of your colon and if needed, to take tissue samples for analysis. This test, inserts a thin tube with a camera into your anus to see the inside of your colon.
Tissue analysis is also typically done through a biopsy to identify the cancer cell type, which is critical to finding the best treatment option for you.

Overview
Stage 3B Colon Cancer is when one of the following is taking place:
1. The Cancer has spread to the deepest layer of your colon called the Serosa or the tissue that covers most of the organs in your abdomen called the visceral peritoneum or has affected 1-3 lymph nodes seen here on the left.
or
2. The Cancer has spread to 4-6 lymph nodes shown here in the middle image,
or
3. The Cancer has spread to the top and intermediate layers of your colon and has affected 7 or more lymph nodes.

Stage 3C Colon Cancer is when one of the following is taking place:
1. The colon cancer has spread to the tissue that covers most of the organs in your abdomen called the peritoneum and has affected 4-6 lymph nodes seen here in green,
or
2. The colon cancer has spread to the deepest layer of your colon called the Serosa or the tissue that covers most of the organs in your abdomen (peritoneum) and has affected 7 or more lymph nodes shown here in the middle image,

3. The colon cancer has spread to nearby organs such as the kidney, cervix, the vagina in women, or the prostate in men and has affected at least 1 lymph node or nearby tissue.

Stage 3 Colon Cancer Prevention
While specific prevention for Stage 3 colon cancer is not applicable since Stage 3 is an advanced stage of cancer, general prevention strategies to reduce the risk of developing colon cancer include:
- Regular Screening: Begin screening for colon cancer at age 45, or earlier if at higher risk, using methods such as colonoscopy to detect and remove precancerous polyps.
- Healthy Diet: Eat a diet rich in fruits, vegetables, and whole grains, and low in red and processed meats.
- Regular Exercise: Engage in regular physical activity.
- Maintain a Healthy Weight: Keep your weight within a healthy range.
- Limit Alcohol: Consume alcohol in moderation.
- Avoid Tobacco: Do not smoke.
- Manage Chronic Conditions: Address and manage conditions like inflammatory bowel disease, which increase the risk of colon cancer.

Stage 3 Colon Cancer Definition
Stage 3 colon cancer is when a mass of cells called a tumor spreads (metastasizes) beyond the lining of the colon to nearby lymph nodes—small structures that are part of the immune system. Although the lymph nodes will contain cancer cells, the disease will not yet have spread to distant organs in the body, such as the liver or lungs.

Stage 3 Colon Cancer Survival Rate
According to SEER data, Stage 3 Colon Cancer has a survival rate of 72.8%. For example, if the 5-year relative survival rate for a specific stage of colon cancer is 72.8%, it means that patients who have that cancer are, on average, about 72.8% as likely as patients who don’t have that cancer to live for at least 5 years after being diagnosed.

Stage 3 Colon Cancer Symptoms
Colon cancer symptoms are more noticeable in stages 3 and 4. These includes:
- changes in stool color
- changes in stool shape, such as narrowed stool
- blood in the stool
- excessive fatigue
- vomiting
- constipation/diarrhea
- abdominal cramps

Stage 3 Colon Cancer Recurrence Rate
The overall prognosis for stage 3 colorectal cancer shows an excellent outcome of 72.8% for the 5-year survival rate, and 31% of the patients still experience recurrence.

Stage 3 Colon Cancer Treatment
Stage 3 colon cancers have spread to nearby lymph nodes, but they have not yet spread to other parts of the body.
Surgery to remove the section of the colon with cancer (partial colectomy) along with nearby lymph nodes, followed by adjuvant chemo is the standard treatment for this stage.
