Coloretal cancer is a common digestive tract tumor with high malignancy. If it is not detected timely, the patient's condition is usually already in the middle or late stages. There are three main methods for coloretal cancer diagnosis: rectal digital examination, fecal occult blood test, and rectal endoscopy. Rectal endoscopy has the highest accuracy, while rectal digital examination has the highest usage rate.
Rectal cancer and coloretal cancer are collectively referred to as coloretal cancer, which is a common malignant tumor of the digestive system. The incidence of coloretal cancer is only second to lung cancer and gastric cancer. If not diagnosed timely, the patient's life expectancy is very short. Therefore, early coloretal cancer diagnosis is particularly important. There are several methods for diagnosing coloretal cancer, which can be confirmed from three aspects. Now we will explain this issue in detail for you, hoping to be helpful. Currently, there are many methods for diagnosing coloretal cancer, but the following three are commonly used in clinical practice.
Coloretal cancer diagnosis: rectal digital examination
Rectal digital examination is a simple and quick operation, and is the preferred diagnostic method. Doctors only need one finger to predict whether there is tumor growth in the patient's intestine, and can also preliminarily determine the location of the tumor growth. If the patient has a recent change in bowel habits, he or she should go to the hospital for rectal digital examination as soon as possible.
Coloretal cancer diagnosis: fecal occult blood test
The fecal occult blood test, also known as the Guaiac test or the Hemoccult test, can detect small amounts of blood in the stool, and is currently the most common detection method in coloretal cancer screening. As long as the blood in the stool exceeds 10 microliters, it can be accurately detected.
Coloretal cancer diagnosis: rectal endoscopy
Rectal endoscopy is the gold standard for diagnosing coloretal cancer. The endoscope can directly observe the overall situation of the human intestinal tract, and can clearly see the lesions in the rectum, sigmoid colon, and splenic flexure under visualized field. If suspected tumor tissue is found through rectal endoscopy, a pathological biopsy can be taken to clarify whether coloretal cancer is present, with an accuracy rate of up to 95%.
In summary, there are the above-mentioned methods of coloretal cancer diagnosis. We have provided a detailed introduction for you. coloretal cancer is a common malignant tumor of the digestive tract with high malignancy. If not detected timely, it can lead to poor prognosis. There are three main methods for diagnosing coloretal cancer: rectal digital examination, fecal occult blood test, and rectal endoscopy. Among them, rectal endoscopy has the highest accuracy, while rectal digital examination has the highest usage rate.
