Updated Guidelines for Screening and Prevention of 20 Malignant Tumors including colorectal cancer, lung cancer, breast cancer, liver cancer, stomach cancer, and thyroid cancer……..
Since the World Health Organization clearly proposed the “three early” strategy of early detection, early diagnosis, and early treatment of cancer, cancer screening, early diagnosis and early treatment have been recognized as the most effective way to prevent and control cancer.
According to the World Cancer Report issued by the World Health Organization, it is predicted that by 2025, the number of new cancer cases worldwide will increase to 19 million annually, to 22 million by 2030, and to 24 million by 2035.
The three most common cancers in the world in 2018 were lung cancer (2.1 million), breast cancer (2.1 million), and colorectal cancer (1.8 million). The top three cancers with fatality rates were lung cancer, colorectal cancer, and gastric cancer. Approximately 9.6 million people worldwide die of cancer each year.
1. Colorectal cancer
1. Asymptomatic people over 45 years old;
2. Two weeks of anorectal symptoms over the age of 40 (refers to any of the following symptoms lasting more than two weeks: changes in stool habits (constipation, diarrhea, etc.); changes in stool shape (feces become thinner); changes in stool properties (hematochezia, mucous stools, etc.) ; People with pain in a fixed part of abdomen);
3. Patients with long-term ulcerative colitis;
4. People after colorectal cancer surgery;
5. People after colorectal adenoma treatment;
6. Immediate relatives with family history of colorectal cancer;
7. An immediate family member of a patient diagnosed with hereditary colorectal cancer (referring to familial adenomatous polyposis (FAP) and hereditary non-polyposis colorectal cancer (HNPCC)) who is over 20 years old.
1. “General population” screening that meets 1~5:
(1) Colorectal cancer screening starts at the age of 45, regardless of men and women, fecal occult blood (FOBT) testing is performed once a year, and colonoscopy is performed once every 10 years until the age of 75;
(2) Those who are 76 to 85 years old, who are physically fit and whose life expectancy is more than 10 years, can continue to be screened;
(3) If you are over 85 years old, it is not recommended to continue screening.
2. Screening of immediate family members with “family history of colorectal cancer”:
(1) 1 first-degree relative has clear high-grade adenoma or cancer (onset age less than 60 years old), 2 or more first-degree relatives have clear high-grade adenoma or cancer (any age of onset), starting at 40 years old (Or start 10 years younger than the age of onset of the youngest person in the family) screening, FOBT examination once a year, colonoscopy once every 5 years;
(2) High-risk subjects with a family history of first-degree relatives (only one, and the age of onset is older than 60 years): Start screening at the age of 40, FOBT test once a year, and colonoscopy once every ten years.
3. Screening for family members of “hereditary colorectal cancer” that meets 7: For family members of FAP and HNPCC patients, when the first case gene mutation in the family is clear, gene mutation test is recommended.
(1) Those who have a positive gene mutation test, after the age of 20, undergo colonoscopy once every 1 to 2 years;
(2) Those who have a negative gene mutation test shall be screened according to the general population.
4. Recommendations on screening methods:
(1) FOBT testing + questionnaire survey is the main screening method, with sufficient evidence;

2. Healthy diet, increase the intake of crude fiber and fresh fruits, and avoid high-fat and high-protein diets;

1. It is not recommended to screen for ovarian cancer in asymptomatic, non-high-risk women.
2. It is recommended that the above-mentioned high-risk women who have not undergone preventive fallopian tube-oophorectomy surgery should be regularly screened for early detection of ovarian cancer. However, there is currently no evidence that ovarian cancer screening can bring clinical benefits to high-risk women.
(1) According to the judgment of clinicians, high-risk women from 30 to 35 years old can consider receiving regular ovarian cancer screening;

(3) Pain and joint dysfunction may appear, and gradually worsen;
(4) The local skin temperature of the tumor is often higher than that of the surrounding normal tissues, which may be accompanied by inflammatory manifestations such as redness and swelling.
Pay attention to the four early signs of soft tissue sarcoma, and go to the soft tissue tumor specialist in time for medical treatment if abnormalities occur.
1. Physical examination: The tumor is generally qualitatively preliminarily qualitative based on 7 aspects including the location, size, boundary, mobility, tenderness, skin temperature and accompanying symptoms of the tumor.
2. Imaging: B-ultrasound, X-ray, CT, MRI, etc. For extremity soft tissue sarcomas, MRI is preferred over CT. High-risk patients should undergo chest CT to rule out lung metastases. At the same time, the regional lymph nodes should be checked.
3. Biopsy: soft tissue sarcoma biopsy, including needle biopsy and incision biopsy. Fine needle or thick needle puncture, if necessary, CT or B-ultrasound guidance. Difficulty or failure of puncture can be performed by surgical incision biopsy.
1. Avoid radiation and strong ultraviolet radiation, and increase the intake of β-carotene, carotenoids, vitamin C and E; 2. Reduce exposure to chemical materials, screen for virus infection, and treat the infection in a timely manner;
3. Eat a reasonable diet, enhance physical exercise, and improve immunity.
1. Those with a family history of leukemia;
2. Patients with blood diseases;
3. People who have had a history of exposure to benzene and organic solvents containing benzene;
4. People who have ever been exposed to X-rays, γ-rays and other ionizing radiation environments;
5. People with abnormal autoimmune function;
6. People with bad habits such as smoking, alcohol abuse, drug abuse, irregular work and rest;
7. Those who have no incentive for chronic bleeding, such as skin bruises, nose bleeding, bleeding gums, menorrhagia, etc.;
8. People who are physically exerted, tired and accompanied by bone and joint pain.
High-risk population: clinical physical examination, once a year.
The clinical physical examination includes the following items:
(1) Surgical physical examination: palpation of superficial lymph nodes and liver and spleen;
(2) B-ultrasound examination: superficial lymph nodes, liver and spleen and abdominal lymph nodes;
(3) Blood routine.
1. Avoid environmental contact with benzene and related chemicals and chemical products;
2. Avoid or reduce ionizing radiation such as X-rays and gamma rays, and quit smoking;
3. Regular physical examinations.
