What are the common methods for diagnosing rectal cancer

Generally speaking, the symptoms of early rectal cancer are not obvious, which also causes many patients to fail to detect the disease in time and induce malignant cancer, which poses a huge danger to the patient's body and may even lead to the loss of life. It is necessary to actively diagnose Tulaoshi.com treatment. Next, let's look at the diagnosis method of rectal cancer.

Oncologists told us that with the continuous development of medical technology, there are many more clinical diagnostic methods for rectal cancer, the most common of which are:
1. Medical history. Usually, doctors should first ask about the medical history in detail, which can often reveal the diagnosis of the disease. Usually, if there are unexplained weight loss, anemia, changes in bowel habits, mucus stool, bloody stool, intestinal obstruction and other symptoms, the possibility of this disease should be considered. In order to detect the disease early, some people who have no obvious symptoms but have a family history of the disease, those who have suffered from multiple colon polyposis, ulcerative colitis, or have received pelvic radiotherapy or cholecystectomy, should be followed up and re-examined regularly.
Second: Physical examination. In clinical practice, a comprehensive physical examination of the patient not only helps to make a correct diagnosis, but also can estimate the severity of the disease and the invasion and metastasis of the cancer. Local signs should pay special attention to intestinal obstruction, abdominal mass and abdominal tenderness. Since the vast majority of rectal cancers occur in the rectum and sigmoid colon, a rectal digital examination is essential. Whenever a patient has symptoms such as blood in the stool, changes in bowel habits, and deformed stools, a rectal digital examination should be performed.
3. Population survey. After years of clinical observation, it was found that the incidence of the disease is increasing year by year, the mortality rate is high, and the five-year survival rate is closely related to the Dukes stage. Since the cause of the disease is unknown, the improvement of the survival rate depends on secondary prevention, that is, early diagnosis of the disease. Early diagnosis includes two meanings: one is early detection, and the other is early diagnosis.
