How to correctly diagnose that you have colorectal cancer?

Colorectal cancer is also rectal cancer. Some adverse factors in life can lead to the occurrence of colorectal cancer. Understanding the diagnosis of colorectal cancer is of great help to the treatment of patients. So, what are the diagnostic bases for colorectal cancer ? Let's take a look at how experts answer the diagnosis of colorectal cancer.

Diagnosis of Colorectal Cancer:

1. X-ray barium enema. Through this method, we can accurately locate cancer. It can be used in conjunction with colonoscopy to make up for the inability to detect small lesions on its own.

2. Fecal occult blood test, but it lacks specificity and needs to be considered comprehensively based on multiple test results. Its advantage is that it is simple and easy to perform and the cost is relatively low.

3. Rectal examination is an effective method for rectal examination, and it is simple and easy to operate. The incidence of rectal cancer in my country is also relatively high. Rectal examination can confirm the diagnosis of a considerable number of patients. Rectal examination has also become a routine diagnostic method for colorectal cancer that cannot be ignored. However, it is difficult to detect small tumors by rectal examination.

4. Colonoscopy is the best way to diagnose colorectal cancer. We can use colonoscopy to observe changes in the intestinal wall and intestinal cavity of the entire colon, and determine the location, size and infiltration range of the cancer. Biopsy can be taken for diagnosis. Through the results of colonoscopy, we can have a clearer understanding of the cancer, which is also crucial to determine the treatment method. However, due to the relatively complex operation and relatively high price, it is not easy to use for large-scale screening.

The above is the diagnosis of colorectal cancer. Through the expert's introduction, I believe you have a certain understanding of the diagnosis of colorectal cancer. If you have any questions about the diagnosis of colorectal cancer, please consult our online experts.
