are hemorrhoids dangerous,Who must have colonoscopy?

    Recently, my grandfather discovered the advanced stage of bowel cancer, which shocked the endoscopist of my family! In fact, he paid special attention to the physical examination every year. Only stool bleeding was treated as hemorrhoids, and he had the first colonoscopy last month. . .

    Sure enough, gastrointestinal cancers in China are as common as a cold, and they are often found in the middle and late stages. According to statistics, our early detection rate of colorectal cancer is less than 20%. What is more frightening is that the trend of younger colorectal cancer in China is obvious. The average age of onset is 48 years old, which is 20 years younger than the average age of onset in the United States (69 years). .

    If detected early and treated in time, colorectal cancer may be cured.

    Risk factors for colorectal cancer

    obesity

    Smoking

    Excessive drinking

    Excessive intake of red meat and processed meat products

    Lack of physical activity

    Family history

    Genetic factors (such as cancer susceptibility syndromes such as gene mutations)

    Intestinal diseases (such as colorectal adenoma, ulcerative colitis, Crohn's disease, schistosomiasis, etc.)

    Other high-risk factors, such as paraneoplastic syndrome.

    According to the expert consensus on early diagnosis and screening strategies for colorectal cancer in China in 2018,

    Those who meet any one or more of the following are classified as high-risk groups

    1. First-degree relatives have a history of colorectal cancer

    2. I have a history of cancer or any malignant tumor

    3. I have a history of intestinal polyps

    4. Those who have two or more of the following:

    1. Chronic constipation (constipation has been more than 2 months per year in the past 2 years);

    2. Chronic diarrhea (diarrhea has lasted more than 3 months cumulatively in the past 2 years, and the duration of each episode is more than 1 week);

    3. Mucus and blood in the stool;

    4. History of adverse life events (occurring in the past 20 years and causing greater mental trauma or pain to the investigator after the event);

    5. History of chronic appendicitis or appendectomy;

    6. History of chronic biliary disease or history of cholecystectomy.

    Recommended screening target: the general population between 40 and 74 years old, with urban population as the priority target.
