    1What are the changes in bowel movements for colorectal cancer?

    Everyone has their own bowel habits, once a day or once every 2 to 3 days, occasionally diarrhea or constipation, but as long as they conform to their daily routines, they will have normal bowel movements. When colorectal cancer appears, bowel habits change.

The blood in the stool of colorectal cancer is mainly a mixture of mucus, blood, and stool. The blood is usually dark red, accompanied by changes in stool characteristics, as well as symptoms such as abdominal pain and abdominal masses. However, in the early stage of colorectal cancer, blood in the stool is not visible to the naked eye, and a stool occult blood test is required (through laboratory tests to find whether there are blood cells in the stool). Therefore, if there is blood in the stool, the patient should not panic or underestimate it, and go to the hospital for examination in time.

As the intestinal obstruction gets worse, the symptoms of abdominal pain will also get worse. After the intestinal obstruction is relieved, the abdominal pain will also be relieved.

    In addition to the above-mentioned common manifestations, as the disease progresses, the tumor grows to a certain extent, and the patient will have systemic symptoms such as anemia and weight loss.

    Colorectal cancer is one of the most common malignant tumors of the digestive tract, and its incidence ranks third in the world. In 2011, the incidence rate in China was about 23/100,000, and the mortality rate was about 11/100,000, and it is increasing year by year. the trend of. However, early colorectal symptoms are not obvious, and most patients are already at an advanced stage when they are diagnosed. The 5-year survival rate of such patients is less than 10%.
