How long does it take for stomach cancer to form from scratch? How can it be prevented?

It may take up to half a year.

You need to keep your eating habits.

In addition, if we have stomach cancer, it is very likely that there will be lymphatic metastasis, which is very dangerous. It may threaten our own lives and cause some functional disorders, so at this time, once we find out that we have early stomach cancer, we must go to the hospital for treatment, so as to ensure that we will not have any problems. So we're going to be in the early days.

To be able to understand our own body, then we need to go to regular physical examinations, this phenomenon is also very good for us, we can only find the occurrence of such diseases at the first time, so that we will not have more serious dangers.

It takes about 10 years, because stomach cancer is a long-term process, and you need to pay attention to a light diet, quit smoking and alcohol.

Many people are very afraid of stomach cancer, in fact, early stomach cancer is not terrible, in the early stage of the patient with a positive attitude to accept** is a high probability of can**, chemotherapy can be used, because the effect of chemotherapy is better, but chemotherapy for some weak patients will leave some ***, and palliative resection surgery can also be taken, but at this time to consider the patient's physical condition, but if the symptoms of stomach cancer are relatively mild, you can temporarily not consider surgery.

The formation of stomach cancer is a lengthy process that usually takes 6 to 10 years. It develops from chronic superficial gastritis to atrophic gastritis, then to intestinal metaplasia, and then to dysplasia and then to gastric cancer. To prevent cancer, it is necessary to develop good eating habits and avoid irregular diets.

It generally takes more than ten years for stomach cancer to develop, so if we want to effectively prevent cancer, we must eat less pickled, fried and other bad foods, and at the same time go to bed early and stay up late.

It takes a long time for stomach cancer to form from scratch, so you can eat a reasonable diet to prevent it.

If you want to have a healthy body, you must have a good lifestyle. If you often stay up late, smoke or drink, it will also have a great impact on your body, and even cause stomach cancer. Therefore, everyone must have a good living habit, and if you feel that your stomach is not very comfortable, you must go to the hospital for examination in time.

Because in the process of examination, you can also know the specific condition of the body.

Stomach cancer starts from scratch, but it takes about a year to two years, staying up late for a long time, eating irregularly, and often overeating, which will cause stomach cancer.

Regarding the natural development time of gastric cancer, that is, the time from the occurrence of carcinoma in situ to the time of death. Because it is difficult to determine the exact time of the initial onset of gastric cancer, there is little data on the natural history of gastric cancer, Chen Guoxi et al. reported the time from the initial appearance of symptoms to death, in the statistics of 3 cases of gastric cancer: the longest life expectancy year, the shortest life expectancy year, and the average year.

Henan reported the natural development time of esophageal cancer. The mean time from positive esophageal exfoliated cells to X-ray confirmation of early esophageal cancer is months, and the average time from dysphagia to death in advanced stages is months. The 19 patients had a total course of illness, with a maximum of 78 months and a minimum of 23 months, with an average of 43 months.

It is believed that the average survival of esophageal cancer from diagnosis to death is 9 months to 1 year according to the literature in the past. Only one of esophageal cancers is reflected.

The process is not the whole process of esophageal cancer. The natural history of gastric cancer, according to the statistics of the Institute of Oncology of China Medical University, 40 cases of gastric cancer without effective ** were observed: the median survival of the average life expectancy was months, and the average survival time was months from the date of hospitalization to the date of death (the average survival time from onset to death was months.

is relative. course of the disease.

50% die within a year. These data are.

It does not represent the natural development of carcinoma in situ without **. In particular, if the site of gastric cancer is not as prone to obstruction as esophageal cancer, which affects dietary intake, the natural course of the disease may be longer than that of esophageal cancer, but unfortunately no information is available in this regard. However, according to the analysis of the relationship between the transformation and exposure time of different gastric mucosal lesions in the population with high incidence of gastric cancer in China, starting from the age of 30, the age span of the intersection of the two curves from chronic atrophic gastritis to dysplasia in the horizontal coordinates is years, indicating the average time required from chronic atrophic gastritis to dysplasia at the age of 30, and the evolution of gastric mucosal dysplasia has been observed in 125 cases in China, and the average time from the initial diagnosis of mucosal dysplasia to the discovery of gastric cancer is months (2 13 months).

It has also been reported that most gastric cancers occur within 3 years after the initial diagnosis of precancerous lesions of the gastric mucosa, and the average time of carcinogenesis is years. By analogy, the natural course of transformation from severe dysplasia to in situ gastric cancer to death is estimated to be longer than that of esophageal cancer. A group of 56 cases of early-stage gastric cancer were reported in Japan, and 50% of the patients who were not operated on developed advanced gastric cancer after 37 months, 80% and 90% after 4 to 5 years, respectively. The average duration of early gastric cancer lesions diagnosed by gastroscopy is about 5 years; The 5-year survival rate of unoperated early gastric cancer is 77 months.
