Ye Chen knew that Xiao Yang told him like that, and he was kind enough to remind him when he was familiar with him. However, Ye Chen didn't think so, even if he really didn't cure the old woman at that time, the old woman's family wanted to trouble him, he was not afraid.

Of course, Ye Chen knew that with his own medical skills, in the case of treating patients with his heart, he would compare his heart to his heart, and the family members of ordinary patients would really not trouble him, but would be grateful to him.

Judging from the fact that he studied medicine with his grandfather and the patients he came into contact with, this is all the case, that is, after he came to Shanghai from his hometown, he only encountered or heard about the medical troubles.

Ye Chen followed Xiao Yang to his office, and when Xiao Yang sat down and talked to Ye Chen about stomach cancer, Ye Chen didn't expect that the incidence of stomach cancer would be so high in China.

According to the relevant survey, gastric cancer ranks first among all kinds of malignant tumors in China, and there are obvious regional differences in the incidence of gastric cancer, and the incidence of gastric cancer in the northwest and eastern coastal areas of China is significantly higher than that in the southern region.

The incidence is high in people over 50 years of age, and the ratio of male to female incidence is 2:1. The prognosis of gastric cancer is related to the pathological stage, location, tissue type, biological behavior, and treatment measures of gastric cancer.

From the perspective of Western medicine, the causes of gastric cancer can be roughly divided into several categories. First, the regional environment and dietary factors.

There are obvious regional differences in the incidence of gastric cancer, and the incidence of gastric cancer in the northwest and eastern coastal areas of China is significantly higher than that in the southern regions.

The high incidence of distal gastric cancer in people who consume smoked and salted foods for a long time is related to the high content of carcinogens such as nitrites, mycotoxins, polycyclic aromatic hydrocarbon compounds and other carcinogens in food, and the risk of gastric cancer in smokers is 50% higher than that in non-smokers.

Second, it is related to Helicobacter pylori infection, and the Hp infection rate of adults in areas with a high incidence of gastric cancer in China is more than 60%.

Helicobacter pylori can promote the conversion of nitrate into nitrite and nitrosamine and cause cancer; Hp infection causes chronic inflammation of gastric mucosa, coupled with environmental pathogenic factors to accelerate the excessive proliferation of mucosal epithelial cells, leading to aberrations and carcinogenesis; the toxic products of Helicobacter pylori CagA and VacA may have pro-cancer effects, and the detection rate of anti-CagA anti-detection in gastric cancer patients is significantly higher than that of the general population.

Third, precancerous lesions. Fourth, heredity is related to genes.

Gastric diseases include gastric polyps, chronic atrophic gastritis, and gastric remnants after partial gastrectomy, all of which may be accompanied by chronic inflammatory processes of different pathologies, gastric mucosa, intestinal metaplasia, or atypical hyperplasia, which may turn into cancer.

Precancerous lesions refer to the histopathological changes of the gastric mucosa that are prone to cancer, and are borderline pathological changes in the process of transforming from benign epithelial tissue to cancer.

Dysplasia of the gastric mucosal epithelium is a precancerous lesion, which can be divided into mild, moderate and severe according to the deformity of the cells.

Genetic and molecular biology studies have shown that the incidence of gastric cancer is 4 times higher than that of the control group in the blood relatives of gastric cancer patients.

Carcinogenesis of gastric cancer is a multifactorial, multi-step and multi-stage development process, involving changes in oncogenes, tumor suppressor genes, apoptosis-related genes and metastasis-related genes, and the forms of genetic changes are also diverse.

The clinical symptoms of gastric cancer are that most patients with early gastric cancer have no obvious symptoms, and a few people have nausea, vomiting or upper gastrointestinal symptoms similar to ulcer disease.

Pain and weight loss are the most common clinical symptoms of advanced gastric cancer. Patients often have more definite upper gastrointestinal symptoms, such as epigastric discomfort, fullness after eating, and worsening epigastric pain as the disease progresses, decreased appetite, and fatigue.

Depending on the location of the tumor, it also has its own special table. Cardia fundus carcinoma may have retrosternal pain and progressive dysphagia, gastric cancer near the pylorus may have pyloric obstruction, and gastrointestinal bleeding symptoms such as hematemesis and melena may occur after the tumor destroys blood vessels.

Persistent abdominal pain often indicates tumor expansion beyond the stomach wall, such as supraclavicular lymphadenopathy, ascites, jaundice, abdominal mass, anterior rectal rectal palpation, and mass. Patients with advanced gastric cancer often have anemia, emaciation, malnutrition and even cachexia.

In Western medicine, the main tests for stomach cancer are X-ray barium swallow examination, fiber gastroscopy, abdominal ultrasound, spiral CT and positron emission imaging.

These are all checked by modern medical devices and can be clearly detected in general. In traditional Chinese medicine, a powerful Chinese medicine practitioner can basically confirm the symptoms of the patient, such as the sudden discomfort in the stomach, becoming emaciated, and then looking at the patient's symptoms.

However, a large number of TCM doctors now also pass guò modern medical device examinations. On the one hand, it can generate income, and the cost of a check-up is not low, and on the other hand, those doctors are not skilled in traditional Chinese medicine, and it is impossible to confirm whether a patient has cancer through dialectic.

Therefore, there is no doubt that the inspection of modern medical devices can not only be quickly confirmed, but also can make more money for the hospital, so why not?

As for the treatment of gastric cancer in Western medicine, one is surgical treatment, including radical surgery, in which the principle is to remove part or all of the stomach including the cancer and the stomach wall that may be infiltrated, and remove the lymph nodes around the stomach as a whole according to the clinical stage standard to reconstruct the digestive tract.

One is palliative surgery, in which the primary lesion cannot be removed, and surgery is performed to alleviate symptoms caused by complications such as obstruction, perforation, bleeding, etc., such as gastrojejunostomy, jejunostomy, perforation repair, etc.

This is the basic surgical treatment for gastric cancer in Western medicine, and other treatments include chemotherapy, radiotherapy, hyperthermia, immunotherapy, etc.

If the patient is lucky enough to be detected at an early stage and cured by surgery, the patient needs to cut part of the stomach and cut off the part where the cancer cells appear to prevent the cancer from spreading, and this part of the patient survives.

However, the most important thing is to prevent the spread of cancer cells after surgery. Therefore, there is an element of luck inside and outside, and there is also a certain amount of time in it, maybe two years, maybe four years, maybe longer, if the cancer cells do not reappear, or do not spread, then it is enough to show that after the surgical incision and cure, the patient's condition is considered stable.

However, the reason why cancer is said to be a terminal disease, which makes people hear that cancer is discolored, is naturally that this cancer is not so easy to treat, and even the cure rate is very low, and it can be said that the mortality rate is very high, so it can be said that it is a terminal disease.

This is also a lot of stomach cancer patients, after the successful operation, but not long after, cancer cells recurrence and spread, patients can only go through chemotherapy, radiotherapy, and other multi-stage treatment, fortunately, can suppress the cancer cells continue to spread, unfortunate like the old man, cancer cells spread wildly, into the advanced stage of stomach cancer, then it is already untreatable.

As for traditional Chinese medicine, Ye Chen said that the word gastric cancer is also a proper noun of foreign Western medicine, and in traditional Chinese medicine, there was no such thing as before, however, the occurrence of gastric cancer is classified into gastric pain, hiccups, fuliang, agglomeration and other categories according to different symptoms in traditional Chinese medicine.

For those who have not studied Chinese medicine, it is naturally difficult to understand why stomach cancer belongs to so many types of diseases in Chinese medicine.

This is similar to the situation in Chinese medicine, where leukemia is classified as a situation of fatigue.
