Tumor
Physical examination is an important way to detect cancer and precancerous lesions early. Various blood test indicators in physical examination, B-ultrasound, X-ray, digital anorectal examination, Pap smear in gynecological physical examination, breast molybdenum palladium film, etc. are all commonly used methods for tumor screening.
blood test
Blood test is an important means to detect early cancer in physical examination. By detecting whether various tumor markers in the blood are elevated, various malignant tumors can be found and differentiated. Such as: alpha-fetoprotein AFP can detect primary hepatocellular carcinoma, gonad embryonic tumors. When carcinoembryonic antigen CEA is significantly elevated, colon cancer, gastric cancer, lung cancer, and cholangiocarcinoma are common; when there is liver cancer, breast cancer, ovarian cancer, and pancreatic cancer, it also rises.
Digital anorectal examination
It can be roughly determined whether there are lesions and the nature of the anus and rectum 7 cm-10 cm from the anal margin. Pap smear in gynecological examination
The Pap staining method can detect early cervical cancer with a detection rate of about 60%-70%.
Ultrasound
Using color Doppler imaging technology, you can clearly find out whether there are masses and lesions in most organs throughout the body.
Chest X-ray
After X-rays pass through the human body, images are presented due to the density of organs and tissues, which can directly show lung tumors, or find chest tumors through indirect changes such as emphysema, obstructive pneumonia, and pleural fluid.
Gastroscope and colonoscopy
Directly observe the color of the stomach and intestinal mucosa, the texture of blood vessels, and the shape of the gland opening to identify the presence or absence of lesions. Suspicious lesions can be diagnosed by biopsy.
