What are the items for colorectal cancer screening

Colorectal cancer screening programs include routine stool examination, stool DNA testing and colonoscopy.

1. Routine stool examination

Routine stool examination is a basic item for colorectal cancer screening. It detects occult blood in the stool to preliminarily determine whether there is any abnormality. Although this method is simple and easy, its accuracy is relatively low. If an abnormal result is found, further examination is usually required for confirmation.

2. Stool DNA testing

This test analyzes DNA in stool to look for signs of cancer or precancerous lesions. It is a relatively new technology with high sensitivity and specificity. It can detect potential problems earlier than routine stool tests, helping doctors intervene at an early stage.

3. Colonoscopy

Colonoscopy is the "gold standard" for screening colorectal cancer. Through colonoscopy, doctors can directly observe the inside of the intestine and find and remove polyps or other suspicious lesions. Although this process may be uncomfortable, its accuracy and comprehensiveness are unmatched by other methods.

4. Screening age recommendations

If you have a family history of tumors or tumor polyps, it is recommended to start screening at the age of 40. This is because these people have a higher risk of colorectal cancer. For people without a family history, it is also very important to have a colonoscopy around the age of 50. This helps to detect problems in the early stages without symptoms and improve the cure rate.

5. Influence of lifestyle

In addition to regular screening, a healthy lifestyle can also reduce the risk of colorectal cancer. Eating more fiber in the diet, reducing the intake of red meat and processed meat, and maintaining proper exercise can all play a preventive role.

6. Psychological preparation and support

Many people are afraid or embarrassed about colonoscopy, so psychological preparation and the support of family and friends are very important. Understanding the examination process, consulting, or even attending related health seminars can help relieve anxiety.

7. The importance of regular review

Even if the initial screening result is normal, you should not take it lightly. Only by following the doctor's advice and regularly checking and paying attention to your own health can you truly prevent problems before they occur.

By understanding these screening items and recommendations, we can better protect the health of ourselves and our families. Regular screening, healthy diet and a positive attitude towards life are the key to preventing colorectal cancer. I hope everyone can pay attention to screening and early detection and early treatment.
