Colorectal cancer is a cancer that forms in the gastrointestinal tract. The colon makes up the first six feet of the large intestine. The rectum makes up the last six inches and ends in the anus. Cancers of the colon and rectum are often grouped together as colorectal cancer.
The large intestine is the last part of the digestive tract. It has two components: the colon, which makes up the first six feet of the large intestine, and the rectum, which makes up the last six inches and ends in the anus. Cancers of the colon and rectum are often grouped together as colorectal cancer.
What is Colorectal (Colon) Cancer? How does it occur?
Colorectal cancers occur when the cells of the colon or rectum divide uncontrollably. The majority of colorectal cancers start as polyps, small overgrowths of tissue in the lining of the colon. Most polyps are benign (non-cancerous), but some may grow out of control and become cancerous.
How severe is Colorectal (Colon) Cancer?
More specifically, most cases of colorectal cancer are adenocarcinomas. Adenocarcinoma refers to cancers that begin in the mucus-producing gland cells that line the intestine. These gland cells can be found within polyps. While there are a few other types of colon cancers, they are rare and treated differently.
Most precancerous polyps produce few if any symptoms, so it is important to get screened regularly for colon cancer. Colorectal cancer screenings allow your doctor to find ad remove polyps before they turn into cancer.
The majority of colorectal cancers are adenocarcinomas that began as adenomas, which are a type of polyp that may become cancer.
How does Colorectal cancer starts?
Colorectal cancer usually starts off in small polyps (overgrowth of tissue) in the colon or rectum. These polyps may not produce any symptoms, especially in the early stages. As the disease progresses, more symptoms may appear.
Symptoms of colorectal cancer includes
Diarrhea or constipation that does not go away
Change in normal bowel habits, such as size, shape, and frequency
Discomfort or urge to have a bowel movement when there is no need
Abdominal pain or cramping pain in your lower stomach
Bloating or full feeling
Change in appetite
Rectal bleeding
Blood in the stool or toilet after a bowel movement
Excessive fatigue
Weight loss without dieting
In the later stages of colon cancer, the polyp may metastasize (spread) to other parts of the body. This can cause other symptoms, depending on where cancer has spread.
These symptoms usually do not mean you have colorectal cancer. But, any time you notice unexplained changes and they persist for more than two weeks, don’t assume they will just go away. See your doctor.

Risk factors
Anything that increases your chance of getting colorectal cancer is a risk factor. Below is a list of Colorectal cancer risk factors:
- Age: Colorectal cancer is most frequently diagnosed in people aged 65-74.
The median age at diagnosis is 67 years old
- Race: African Americans have the highest rate of colon cancer among all racial groups in the United States.
- Family history of colon cancer, rectal cancer, or polyps
- Inflammatory bowel disease (Crohn’s disease or chronic ulcerative colitis)
- Prior history of colorectal cancer or polyps.
- Hereditary cancer syndromes: Some genetic mutations can be inherited and increase your risk for certain types of cancer. Inherited syndromes including hereditary nonpolyposis colorectal cancer (HNPCC or Lynch syndrome and familial adenomatous polyposis (FAP) may put you at higher risk for developing colon cancer
For patients concerned about inherited family syndromes that cause colorectal cancer, we offer advanced genetic testing and counselling to help understand your risk.
Diet: If you eat a lot of red meat, processed meats, or meats cooked at very high heat, you may be at higher risk for colon cancer
