what does a hemorrhoids look like,More and more young people get bowel cancer, what should I do? Meet the following 6 conditions, it is necessary to quickly do colonoscopy

    According to the "2018 China Cancer Registry Annual Report" issued by the National Cancer Center, as of August 30, 2017, colorectal cancer ranks fourth among Chinese men, accounting for 10.13%, and third among Chinese women. , Accounting for 9.25%. In comparison with the world, new cases of colorectal cancer in China are ranked 3rd and 2nd among global men and women respectively, while death cases are ranked 4th and 3rd respectively. In the past 10 years, the overall incidence of colorectal cancer in China has also shown a significant upward trend. It can be seen that the health threat of colorectal cancer to the Chinese people cannot be underestimated.

    Early screening can reduce colon cancer mortality

    In terms of the difficulty of treatment, the later the stage of colon cancer, the more complicated the treatment and the more methods required.

    Stages of colon cancer in stage I, stage II, and stage III are colon cancers that have not yet metastasized. As long as there are no contraindications, patients with stage I and stage II colon cancer can be treated directly with surgery. Chemotherapy is not required after stage I, and chemotherapy depends on the situation after stage II. Stage III colon cancer may invade surrounding tissues and organs, and generally requires a combination of surgery and adjuvant chemotherapy. Stage IV colon cancer belongs to colon cancer with distant metastasis. It is necessary to comprehensively consider various methods such as surgery, radiotherapy, chemotherapy, ablation, and drugs according to the condition. In terms of prognostic effects, the later the stage of colon cancer, the worse the prognosis. According to the results of comparative statistics by Liao Chuanwen, O'Connell and others of the General Surgery Department of Jiangxi Provincial People’s Hospital on the survival rates of nearly 120,000 colon cancer patients in the US NIH-NCI surveillance, epidemiology and SEER databases, I, II, III, The 5-year survival rates of patients with stage IV colon cancer were 93.2%, 82.5%, 59.5%, and 8.1%, respectively.

    This shows the importance of early screening for colon cancer to the prevention and treatment effect.

    Who needs to be screened for bowel cancer?

    People at high risk of colorectal cancer need to pay more attention to early screening. To judge whether you are a high-risk group of colon cancer, you can use the following criteria.

    Over the age of 40, two weeks of anorectal symptoms, including bowel habits, changes in traits, and pain in a fixed part of the abdomen, combined with any of the following conditions:

    a There is a colon cancer patient among the immediate family members;

    b Patients with a history of colorectal adenoma;

    c Patients with chronic ulcerative colitis;

    d Patients after colon cancer surgery;

    e People with family history of familial adenomatous polyposis and hereditary non-polyposis colorectal cancer;

    f Asymptomatic people over 50 years old.

    What are the inspection methods for early colorectal cancer screening?

    At present, there are four main methods for early screening for colorectal cancer.

    One is digital rectal examination, which is the fastest and most convenient way. Experienced doctors can detect most rectal cancers through digital rectal examination, and can also roughly determine the size, location, shape, and depth of invasion of the tumor.

    The second is the detection of fecal occult blood. This is a relatively primitive early screening method, which is also relatively fast and simple, but with average accuracy, and the results of three consecutive tests are relatively reliable.

    The third is blood and stool genetic testing. This is a relatively new technology. By detecting colorectal cancer markers in blood and stool, it can quickly and effectively detect colorectal abnormalities.

    The fourth is colonoscopy. The gold standard for early colorectal cancer screening is still colonoscopy, including colonoscopy, anoscopy and sigmoidoscopy.

    Colonoscopy can directly observe the condition of the patient's colorectal, and can accurately find the abnormal location of cancer or possible cancer. It can also use biopsy forceps to remove suspicious tissue for pathological examination. It is currently the most effective way to screen for colorectal cancer.
