Why didn't physical examination come out?

The general physical examination contents include height, weight, blood pressure, cardiopulmonary auscultation, blood routine, urine routine, liver and kidney function, blood sugar, nail function, blood fat, make an electrocardiogram, take a chest film, add a tumor marker a little bit more, aiming at the complex body structure, the project is a little less. There are several kinds of cancer screening. This kind of routine physical examination can't screen cancer at all. Unless the cancer is in advanced stage, some people can judge that they are very close to each other without examination.

There are also some cancers with lower incidence rate than in the physical examination. Some common cancers, such as lung CT, liver AFP and ultrasound, breast ultrasound and mammography, thyroid ultrasound and liver function, prostate ultrasound and PSA, are also included in some physical examination items. Lymphoma, nasopharyngeal carcinoma, laryngeal cancer and renal cancer are not included in the examination.

Some malignant tumors progress too fast is also one of the reasons that physical examination can not come out. Gallbladder cancer, pancreatic cancer, small cell lung cancer these cancers are really "rapid progress", when the examination is not, or very small, in a short period of time, grow out. So some people say these cancer checkups are useless. At present, there is no perfect screening method for these cancers.

matters needing attention

There are many physical examination items, and the cost is also very large. Some physical examination institutions have 100 yuan package, 1000 yuan package, and even 10000 yuan package.

Hepatitis patients, focus on liver examination, half a year to do AFP and ultrasound; Gastritis, gastric ulcer, HP infection, 1 year to do gastroscopy; Smoking, a family history of lung cancer is not every year to do a chest CT or more appropriate.
