The Benefits of a Colonoscopy
10/14/2022
When we think of cancer prevention, we typically think of those we hear the most about, such as breast cancer or lung cancer. One of the most common cancers is actually colon cancer: cancer of the large intestine and lower part of the digestive system. The American Cancer Society’s estimates for the number of colorectal cancer cases in the United States for 2022 are:
- 106,180 new cases of colon cancer
- 44,850 new cases of rectal cancer
In the United States, colorectal cancer is the third leading cause of cancer-related deaths in men and in women, and the second most common cause of cancer deaths when numbers for men and women are combined. It's expected to cause about 52,580 deaths during 2022.
The exact causes of colon cancer are unknown. One of the most important preventive steps is to get a colonoscopy, a screening test to detect any signs of cancer. A colonoscopy is a procedure to see inside the colon and rectum. Used as either a screening test or a diagnostic tool, it can help your doctor investigate unusual symptoms such as unexplained changes in bowel habits, abdominal pain, rectal bleeding, and weight loss.
A colonoscopy is performed using a long, thin, flexible tube, which is inserted through the rectum into the lower digestive tract, while the patient is sedated or asleep. The tube is equipped with a light and a tiny camera that transmits images of the patient’s intestinal lining to a computer screen located at the bedside. This enhanced view allows the doctor to see inflamed tissue and any abnormal growths.
If polyps (growths) are found during the exam, they are quickly and painlessly removed at that time, and later tested in a laboratory for signs of cancer. Polyps are common in adults, and usually harmless. However, most colorectal cancer begins as a polyp, so removing polyps early is an effective prevention method. Your doctor can also take samples from abnormal-looking tissues – a biopsy – during the colonoscopy, so that any suspicious areas can be examined for signs of disease and treated, if necessary.
The American Cancer Society (ACS) has guidelines for colorectal cancer screening and recommends people at average risk for colorectal cancer begin screening at age 45. In the most recent guideline update, ACS lowered the age to start screening because studies show rates of colorectal cancer among people younger than 50 are on the rise. ACS experts have determined that screening starting at 45 could help save more lives.
Your risk level for colon cancer varies according to your age, gender and ethnic background, as well as your overall health and lifestyle. Factors that affect your risk level include:
- Advancing age (over age 45)
- Male gender
- African American ethnic status
- A family or personal history of polyps(growths inside the rectum or colon), or colorectal cancer
- A high-fat diet
- Certain digestive diseases, diabetes, Crohn’s disease, ulcerative colitis
Depending on your age, a colonoscopy screening may be a covered “wellness” test under your insurance plan – and most plans cover a colonoscopy completely as a follow-up test or diagnostic tool. Check with your insurance provider and your doctor’s office for help in scheduling a screening exam.
