Scheduling a colonoscopy may seem like a daunting task to some, but this test is the most treatable and often curable test for colorectal cancer. It is a lifesaver for many people because it can be detected early. Thanks to cancer screening and removal of precancerous polyps, the diagnosis rate for colon cancer today is half what it was in 1970. According to data, 90% of patients are cured if colon cancer is diagnosed early.
In our area, a significant number of residents are scheduling colonoscopies.In Tompkins, nearly 80% of residents are between 50 and 64 years old. Current New York State health data shows that most of the surrounding counties are screened for colorectal cancer. This far exceeds the 65% testing rate for all state residents in that age group. Screening rates for people 65 and older tend to be similar to or higher than younger patients.. Colon cancer screening plays an important role in this medical success story. If more people are screened, more people could avoid this leading cause of death from cancer.
What types of colon examinations are there?
There are two types of screening:
colonoscopy. This test can identify 98% of colorectal cancers. A colonoscope is a long, lighted tube with a small camera at the end. It is placed inside the rectum and colon and uses a camera to send images to a video monitor for review by your doctor. If polyps or suspicious areas are found, they can be removed and examined.
stool base. These non-invasive tests can be performed at home and require less preparation than tests done in the hospital. Colonoscopy.
Alternative screening options such as flexible sigmoidoscopy and virtual colonoscopy are also available and can be discussed with your gastroenterologist.
How often are screenings held?
A patient’s risk for colorectal cancer is used to determine the optimal type of screening and its frequency. For people at normal risk, we recommend repeat colonoscopies every 10 years and follow-up tests every 1 to 3 years, depending on the type of test. If polyps are identified, the interval between colonoscopies may be changed.
How does a patient prepare for a colonoscopy?
Preparation before a colonoscopy usually begins with a low-fiber diet for several days, followed by a clear liquid diet the day before the procedure. Bowel preparation begins in the afternoon before the colonoscopy. Bowel preparation involves emptying the colon using laxatives. There are various options for this preparation and should be discussed with your gastroenterologist.
What are the pros and cons of each type of colorectal screening?
Colonoscopy.
- A colonoscopy takes 15 to 60 minutes.
- Patients usually require sedation and recovery may take several hours.
- This screening detects smaller polyps than other tests.
- Suspicious tissue or polyps can be removed and examined.
Stool-based testing.
- The test does not require sedation or laxatives and can be performed at home.
- Fecal immunochemical tests (FIT) detect blood in the stool, but are less sensitive for detecting cancer than DNA tests.
- Stool DNA testing can detect approximately 90% of colorectal cancers and 40% of polyps.
- Stool-based tests detect fewer cancers and polyps than colonoscopies. If the test is positive, a colonoscopy will be required to see if polyps or cancer are present.
Who is at highest risk for colorectal cancer?
Colorectal cancer is one of the most diagnosed and preventable cancers, but it does not affect everyone equally. Age and race play a role in this disparity. Although overall colorectal cancer cases and deaths have decreased over the past few decades, the proportion among people younger than 50 years has increased. African Americans, American Indians, and Alaska Natives have the highest incidence of colorectal cancer and are more likely to die from colorectal cancer. than others. The reasons are complex.
When should I start testing for colorectal cancer?
For people at average risk, it is recommended that people get their first test at age 45 and get tested regularly thereafter. Testing at an earlier age and more frequent screening may be done for patients with certain diseases or a personal or family history of colorectal cancer or colorectal polyps.
All patients should tell their health care provider if they experience symptoms such as changes in bowel habits, changes in stool diameter, blood in or on the stool, abdominal pain, or unintentional weight loss.
How can I lower my risk of colon cancer?
- If you have a family history of colon cancer or large polyps, start getting screened for colon cancer starting at age 45. Or it could be sooner.
- Eat a healthy diet that includes lots of vegetables, fruits, and whole grains. Limit processed and red meat.
- Do regular exercise.
- Maintain a healthy weight.
- Please don’t smoke. Limit alcohol intake.
