What is the anti-cancer physical examination?
Anti-cancer physical examination, the professional name is Opportunistic Screening. There are two requirements for screening. The first requirement is to be able to detect relatively early tumors, and the second is to minimize missed diagnosis. It is to discover three situations: early tumors, precancerous state of tumors, and prone to tumor diseases.
What is the difference between a physical examination for cancer prevention and ordinary physical examinations?
physical examination methods are different
ordinary physical examinations, and the method taken may be random screening, which is useful for some tumors that grow very slowly, such as renal cancer . However, there are shortcomings in the detection of early tumors.
Anti-cancer physical examination, many measures are taken to make it easier to detect early tumors. Only when early tumors are found can the mortality rate be reduced.
Example:
1. Breast examination
① Ultrasound of ordinary physical examination can also be found in breast cancer
② Anti-cancer physical examination is a combination of ultrasound and molybdenum targets, making it easier to detect early cancer
2. Colorectal examination
① Ordinary physical examination is to do stool occult blood, that is, test stool, and it depends on many items. For example, looking at parasites, internal medicine diseases, etc., it is not centralized for tumor screening, so it is found that the early tumor benefits are very low
② Gold standard colorectaloscope for anti-cancer physical examination, suitable technology: stool occult blood FIT immunity method, DNA
3. Liver examination
① Ordinary physical examination is to do ordinary ultrasound examination
② Anti-cancer physical examination includes ultrasound and DNA testing and serology markers
③The high-risk population of liver is hepatitis B or hepatitis C , mainly hepatitis B carrying, hepatitis B positive, cirrhosis , and severe fatty liver. It is best for these high-risk populations to have physical examination once every six months
4. Gastric and esophageal examination
①General physical examination generally does not have this
②The main method of anti-cancer physical examination is gastroscopy
0 Upper gastrointestinal tumor is a characteristic of our country Tumors, the incidence of gastric cancer and esophageal cancer in my country are relatively high, so we must check regularly gastroscopy
7 Seven major cancer screening methods
1. Lung cancer: Chest low-dose CT examination
2. liver cancer : B ultrasound + alpha-fetoprotein
3. Breast cancer: Breast B ultrasound + mammography
4. Straightening Intestinal cancer: colonoscopy /sequential screening
5. Gastroenterology cancer: gastroscopy/sequential screening
6. prostate cancer : color ultrasound + PSA
7. cervical cancer : HPV + TCT
Tips
Anti-cancer physical examination is not the more expensive the better. The key is to be targeted and choose the anti-cancer physical examination items and examination methods that suit you.
1. Choose a special anti-cancer physical examination
Many regular hospitals have anti-cancer physical examination packages. You should undergo lung CT when screening for lung cancer, and you should undergo breast color ultrasound and mammography when screening for breast cancer.
2. According to your symptoms and medical history, choose the right plan and everyone's family history, eating habits, and living and working environment are different. In other words, everyone has different high-risk factors and different risks of cancer.
For example, a person who smokes for a long time or smokes second-hand smoke has a high probability of lung cancer; if the mother has breast cancer, the chance of the daughter has breast cancer increased; obese patients are prone to colorectal cancer, pancreatic cancer, , breast cancer and other tumors.
