Colorectal cancer (CRC) is one of the most common and deadly cancers worldwide. According to the World Health Organization (WHO), it is the third leading cause of cancer-related deaths globally. However, with early detection and removal of precancerous polyps, CRC is largely preventable. In recent years, there have been significant updates to CRC screening guidelines, and it's essential for individuals to stay informed about the latest recommendations to protect their health.
The American Cancer Society (ACS) and other major health organizations have been working to improve CRC screening rates and reduce the number of deaths from this disease. One of the primary goals of these efforts is to encourage people to get screened at a younger age and more frequently, as the risk of CRC increases with age. By understanding the updated guidelines and taking proactive steps, individuals can significantly reduce their risk of developing CRC and improve their chances of survival if the disease is detected.
Updated CRC Screening Guidelines: What You Need to Know
The ACS has updated its CRC screening guidelines to recommend that adults with an average risk of CRC start regular screening at age 45. This is a significant change from previous guidelines, which recommended starting at age 50. The new guidelines also suggest that adults between 45 and 75 years old get screened every 10 years with a colonoscopy or every 5 years with a flexible sigmoidoscopy or CT colonography.
For individuals between 76 and 85 years old, the guidelines recommend that they discuss the risks and benefits of screening with their healthcare provider and make an informed decision about whether to continue screening. Adults over 85 years old are generally not recommended for CRC screening, as the benefits of screening may be outweighed by the risks at this age.
Types of CRC Screening Tests: Which One is Right for You?
There are several types of CRC screening tests available, each with its own advantages and disadvantages. The most common tests include:
- Colonoscopy: This is considered the gold standard for CRC screening. During a colonoscopy, a flexible tube with a camera and light is inserted into the colon to visualize the inside of the colon and rectum.
- Flexible Sigmoidoscopy: This test is similar to a colonoscopy but only examines the lower part of the colon.
- CT Colonography: This test uses a CT scan to visualize the colon and rectum.
- Stool Tests: These tests check for blood or DNA in the stool, which can indicate the presence of CRC.
It's essential to discuss the risks and benefits of each test with your healthcare provider to determine which one is right for you.
| Screening Test | Frequency | Age Range |
|---|---|---|
| Colonoscopy | Every 10 years | 45-75 |
| Flexible Sigmoidoscopy | Every 5 years | 45-75 |
| CT Colonography | Every 5 years | 45-75 |
Key Points
- Adults with an average risk of CRC should start regular screening at age 45.
- The recommended screening interval is every 10 years with a colonoscopy or every 5 years with a flexible sigmoidoscopy or CT colonography.
- Adults between 76 and 85 years old should discuss the risks and benefits of screening with their healthcare provider.
- There are several types of CRC screening tests available, each with its own advantages and disadvantages.
- Early detection and prevention are key to reducing the risk of CRC.
Why Are CRC Screening Guidelines Changing?
The CRC screening guidelines are changing due to new evidence and research. Studies have shown that:
1. The incidence of CRC is increasing in younger adults.
2. CRC is often diagnosed at more advanced stages in younger adults.
3. Screening can detect and remove precancerous polyps, reducing the risk of CRC.
By starting screening at a younger age, individuals can reduce their risk of developing CRC and improve their chances of survival if the disease is detected.
What Can You Do to Stay Ahead of CRC?
To stay ahead of CRC, follow these steps:
- Know your risk: Understand your family history and risk factors for CRC.
- Get screened: Start screening at the recommended age and follow the recommended screening interval.
- Maintain a healthy lifestyle: Eat a balanced diet, exercise regularly, and don't smoke.
- Discuss your risk with your healthcare provider: If you have a family history of CRC or other risk factors, discuss your risk with your healthcare provider.
