Experts explain the specific diagnostic steps for colorectal cancer

In medicine, the diagnosis of colorectal cancer needs to be done step by step, so that it can be diagnosed more accurately. So what are the specific steps for diagnosing colorectal cancer ? Let's ask the experts to tell you about the specific steps for diagnosing colorectal cancer.

Generally, the specific steps for diagnosing colorectal cancer are:

1. Medical history

When examining each disease, the doctor first needs to ask about the medical history in detail, which is of great significance for the diagnosis of colorectal cancer. For example, if a middle-aged or older person has unexplained weight loss, anemia, changes in bowel habits, mucus in the stool, blood in the stool, intestinal obstruction, etc., the possibility of this disease should be considered. This is the first step in the diagnosis of colorectal cancer.

2. Physical examination

Usually, after inquiring about the patient's medical history, the diagnosis of colorectal cancer also requires a comprehensive physical examination, which not only helps in the diagnosis of colorectal cancer, but also can estimate the severity of the disease, the invasion and metastasis of cancer, and serve as a reference for formulating a reasonable treatment plan.

3. Professional diagnosis

There are various methods for diagnosing colorectal cancer, such as: 1. Fecal occult blood test This test is usually based on the lesion of the disease, such as bleeding of varying degrees due to mucosal erosion and ulceration. Therefore, a simple and easy fecal occult blood test can be used to monitor colorectal cancer. The early fecal occult blood test was a chemical colorimetric method, and the commonly used reagents were benzidine or guaiac. 2. Serum CEA detection In clinical practice, the serum CEA level of most patients is often elevated, but the specificity of this test is not strong. In some non-digestive tract tumors and benign lesions, the serum level can also be elevated. This is an important step in the diagnosis of colorectal cancer.

The above is an introduction to the specific steps of colorectal cancer diagnosis, I hope it will be helpful to everyone. Once you have colorectal cancer, you must go to the hospital for treatment immediately to avoid delaying the disease.
