The answer is: no!
Gastrointestinal endoscopy found that the cure rate of early cancer was 90-97%! The 5-year survival rate of gastrointestinal tumors seen by CT is less than 30%!

An embarrassing story.
The following is a sad story. Mr. Wang, 53, has had a stomachache for more than a month. Besides loss of appetite, he often has abdominal distension. After self-treatment, it still doesn't improve intermittently.
After arriving at the hospital, the doctor prescribed blood routine, C 14 examination and gastroscopy, but Mr. Wang was very resistant to gastroscopy, saying, "I am not afraid of pain or spending money. I was afraid of hurting my stomach, so I put a thick tube in my stomach ... and I just had a comprehensive physical examination before the Spring Festival. CT and cancer screening are fine. I just have indigestion. "
After repeated communication by doctors, she still insisted on doing only the first two tests, and the final result was moderate anemia and helicobacter pylori infection.
The doctor told her: "Miss Wang, you are Helicobacter pylori positive and have digestive tract symptoms." What matters is the risk of anemia and digestive tract cancer. You have to do a gastroscope first! "
"Isn't it helicobacter pylori infection? Please help yourself to some medicine. Nature is not anemia after digestion. "
"I suspect that your anemia is not caused by indigestion."
"It must be, I can't eat much during this period."
"Gastroscope is an irreplaceable examination for checking stomach diseases, and it must be done!"
"Let's talk about it after taking the medicine .."
Although he advised for a long time, Mr. Wang refused gastroscopy. Finally, only four kinds of anti-Helicobacter pylori drugs were prescribed, and some Chinese patent medicines for regulating qi and relieving pain were added.
Before leaving, she yelled at her: "If this symptom still exists after 2 weeks, you must have a gastroscope!"
It has been three months since Miss Wang came to the hospital again. At this time, her stool was black, emaciation, abdominal pain aggravated, and the results of gastroscopy were even more embarrassing: advanced gastric cancer.
CT showed that gastric wall thickening and multiple lymph node metastasis brought great difficulties to radical operation.
Although Mr. Wang later chose surgery, he died unfortunately six months later.
Can other tests find early gastrointestinal cancer?
Almost nothing!
a.
Image inspection
Abdominal organs can be divided into two categories: solid organs (liver, spleen, kidney, pancreas) and hollow organs (gastrointestinal tract).
Our intestines and stomach belong to hollow organs, one is like a bag and the other is like a tube.
CT, B-ultrasound, magnetic resonance imaging and other imaging methods have good detection rate of solid organ lesions, but most of them are difficult to be used for hollow organ examination.
Especially in early digestive tract tumors, the lesions are mostly confined to the innermost mucosa and submucosa, so it is necessary to observe the lesions in the digestive tract cavity with the help of endoscope.
So by the time CT and MRI find the problem, the tumor has grown up, and most of it belongs to the middle and late stage!
Barium meal in digestive tract can not be used to screen early cancer, but can only diagnose some special diseases, such as esophageal achalasia and gastroptosis.
b.
blood test
General gastrointestinal screening will recommend fecal occult blood, four stomach functions, five cancer screening (tumor markers), genetic screening and so on.
Tumor rupture can cause bleeding, and fecal occult blood test is to check whether there is occult bleeding in gastrointestinal tract. Early tumors, especially small cancers, do not bleed at the early stage;
Gastric function test is mainly to check gastrin and pepsinogen to determine whether the secretion is normal, but to screen whether it is a high-risk group of gastric cancer. If there is any abnormality, gastroscopy must be done immediately;
Tumor markers can only be said to have certain value, but they can never be used as the only reference for screening tumors!
Because some inflammation can also lead to the increase of tumor markers, some tumors are normal in the middle and late stages. If they are tall, don't be afraid. Normal is not a gold medal for avoiding death!
Genetic testing is more suitable for screening patients with family history of cancer. Even so, it only gives you a reference that you may get cancer, but it doesn't say what your body is like or whether you have early cancer.
How important is gastrointestinal endoscopy?
The digestive tract of human body can be divided into upper digestive tract, middle digestive tract and lower digestive tract from oral cavity to anus. Generally speaking, 90% of diseases are concentrated in the upper and lower digestive tract. Gastroscope and colonoscopy are the most direct and effective methods to check the lesions in these parts.
However, such an important inspection was rejected by many people. Fear of gastroscope is very common in clinic, mainly because of trouble and pain.
Refusing endoscopy is a challenge to one's life. Among the top five tumors in China, there are four kinds of digestive system tumors, namely gastric cancer, esophageal cancer, colorectal cancer and liver cancer. However, most people will not take the initiative to go to the hospital for screening because they are afraid of gastroscopy and colonoscopy.
There are 23 million cases of gastroscopy and only 5 million cases of enteroscopy in China every year.
0 1 gastroscope
Gastroscopy uses a slender hose (optical fiber+high-definition camera) to enter the gastric cavity and duodenal cavity, observe the mucosa, take photos or treat.
Gastroenteroscopy is the first choice to diagnose esophageal, gastric and intestinal diseases, and it is also the best method to screen early esophageal, gastric and intestinal cancers.
At present, the 5-year survival rate of early gastric cancer is as high as 90%, and if it develops into advanced gastric cancer, the 5-year survival rate is lower than 30%. Unfortunately, China accounts for more than 40% of the new cases of gastric cancer in the world every year, and the early detection rate is less than 10%, far lower than 70% in Japan and 50% in South Korea.
02 colonoscopy
Colonoscopy, also known as electronic fiber colonoscopy, is a slender flexible fiber hose with a diameter of about 1 cm. The front end is equipped with a high-definition camera and a cold light source, so the doctor can directly see the inside of the intestine.
At present, colonoscopy is the first choice for screening colorectal cancer, and it is also the "gold standard" for diagnosing colorectal cancer. It can not only diagnose lesions, but also remove cancerous prostate polyps.
According to the Analysis of the Prevalence of Malignant Tumors in China published by the National Cancer Center in 20 19, there were 388,000 new cases of colorectal cancer in China in 20 18, ranking third among all malignant tumors. Our population is 65.438+0.4 billion. According to the annual demand of 654.38+00% people, there are more than 65.438+0 billion people.
Please consciously check the high-risk groups.
People in the following situations need to go to the hospital for gastrointestinal endoscopy.
1. Upper abdominal pain with nausea and vomiting;
2. Unexplained weight loss, anemia, black stool or oily stool;
3. When X-ray barium meal examination or CT and B-ultrasound examination suspect that the stomach, esophagus and duodenum have morphological changes or local thickening;
4. Patients with previous diseases such as ulcers, gastric polyps and atrophic gastritis;
5. Patients with colorectal cancer after operation, colorectal adenoma and adenomatous hyperplasia should be reexamined every 1-2 years after treatment;
6. People with a family history of colorectal cancer and polyps;
7.45-50 years old healthy population regular screening.
Some people are not suitable for gastrointestinal endoscopy.
1. Severe liver, kidney and lung dysfunction;
2. Severe coronary heart disease and myocardial injury with severe cardiac insufficiency (ventricular fibrillation, etc.). );
3. Menstrual women;
4. Patients with severe nervous system diseases (convulsions, uncontrolled epilepsy, psychosis);
5. Patients with aortic aneurysm;
6. Pregnant women;
7. People with pneumonia or other infections with high fever.
