Tumor
The diagnosis of cancer is mainly through the following ways:
①A detailed medical history, a comprehensive physical examination, various routine tests and specific laboratory tests. Such as alpha-fetoprotein, carcinoembryonic antigen and so on.
②Physical examination: Because about 75% of cancers occur in parts of the body that are easy to find. Therefore, a comprehensive physical examination, including inspection, palpation, percussion, auscultation, etc. is very important. A considerable part of the tumor can often be found and a preliminary judgment can be made on its nature.
③Imaging examinations: including routine X-ray fluoroscopy, filming, various angiography, various tomographic examinations; CT, ECT, MRI examinations; B-mode ultrasound examinations, nuclear medicine examinations, etc.
④ Pathological examination: Exfoliated cytology and biopsy.
⑤ Endoscopy: esophagoscope, fiber gastroscope, fiber colonoscope, bronchoscope, cystoscope, etc.
⑥Radioimmunological examination: such as fetal alpha protein determination, carcinoembryonic antigen test, EB virus antibody test, etc.
⑦Medical laser diagnosis. In addition, carrying out regional cancer prevention surveys is also a valuable early detection approach. Through census, it is very important to be able to find early cancer patients, which is very important to improve the survival rate of cancer patients.
