What is Colorectal Cancer

In the United States, colorectal cancer is the third leading cause of cancer-related deaths in men and women, causing more than 50,000 deaths in 2021. Learn more about this cancer and how you can prevent it below!

What is colorectal cancer

Colorectal cancer is cancer that originates in the colon or the rectum. The colon is also called the large intestine or the large bowel, and the rectum is the passageway that connects the large intestine to the anus. Most colorectal cancers begin as growths in the inner lining of the colon or rectum called polyps. While not all polyps are cancerous, if they are larger than 1 cm, there are more than three polyps, or there is a group of abnormal cells left after a polyp is removed.

Risk factors for colorectal cancer

The most significant risk factor for colorectal cancer is age; as you get older, you are significantly more likely to develop various cancers, including colorectal cancer. However, some other factors can increase your risk. These include:

  • Inflammatory Bowel Diseases, including Chron's disease and ulcerative colitis
  • Family history of colorectal cancer or colorectal polyps
  • Genetic syndromes such as familial adenomatous polyposis (FAP)
  • Lack of regular physical activity
  • A low-fibber and high-fat diet
  • Being overweight or obese
  • Alcohol consumption
  • Tobacco usage

Symptoms of Colorectal cancer

The main sign of developing colorectal cancer is the development of polyps in the rectum or colon. However, many people with these polyps might go years without noticing them.  This is why getting screened for colorectal cancer regularly is essential.  If you have any of the following symptoms, reach out to your provider about colorectal cancer screening, even if you have already had one in the past.

  • A change in bowel habits
  • Blood in or on your stool (bowel movements)
  • Diarrhea, constipation, or the feeling that the bowel is not emptying all the way
  • Abdominal pain, aches, or cramps that don't go away.
  • Unexplained weight loss

How to reduce your risk of colorectal cancer

healthy choices

A diet high in whole grains, fruits, and vegetables and low in fat lowers your risk of colorectal cancer. Other lifestyle changes that reduce your risk of colorectal cancer include: keeping a healthy weight, regular physical activity, limiting alcohol consumption, and avoiding tobacco.

Aspirin

Some studies have shown that low doses of aspirin may be effective in reducing the risk of developing colorectal cancers in some individuals. Talk to your provider to learn more about if aspirin can help you reduce your risk of colorectal cancer.

regular screenings

The number one way to prevent colorectal cancer is to get regular screenings after age 45. Almost all colorectal cancers begin as precancerous growths in the colon or rectum called polyps. These polyps can exist for years in the colorectal lining without causing symptoms. Regular screenings allow your provider to catch these polyps early and remove them before they can develop into colon cancer. If you need a screening, schedule one today by calling 406.454.6973.
