Several specific methods for examining rectal cancer

Among intestinal diseases, rectal lesions are relatively common, and the most serious of them is of course rectal cancer. It is necessary to check for rectal cancer as soon as possible so that you can receive treatment for rectal cancer more promptly and prolong the patient's life. So what are the specific methods for checking rectal cancer ? The following will tell you about the specific methods for checking rectal cancer.

In general, specific examination methods for rectal cancer include:

1. Tumor marker examination: This method of colorectal cancer examination mainly targets two markers for colorectal cancer: CEA and CA-199. If these two markers are elevated before surgery, attention should be paid to the presence of liver and lung metastasis. The positive rate of CEA before surgery is about 30%, and the positive rate is about 70% in case of recurrence after surgery.

2. Stool routine + occult blood: can be used as a simple screening indicator. If the occult blood is positive, it should be taken seriously and further examination should be conducted to understand the digestive tract (stomach, small intestine, large intestine and rectum). This is one of the common examination methods for rectal cancer.

3. Patients with no problems in rectal digital examination should not relax their vigilance. They can undergo further colonoscopy to understand the condition of the rectum and large intestine that cannot be touched by digital examination. This is very important for the examination of rectal cancer. If you do not want to undergo colonoscopy, you can undergo barium enema examination (note that before undergoing colonoscopy or barium enema examination, you must rule out intestinal obstruction. If there is intestinal obstruction, it is forbidden to take laxatives to prepare the intestine).

The above is an introduction to the specific examination methods for rectal cancer. I believe everyone has some understanding of this. These examination methods for rectal cancer can correctly detect rectal cancer. If diagnosed with rectal cancer, you must actively receive treatment. A good attitude can help patients achieve better results.
