Esophageal cancer is a common malignant tumor of digestive system. After esophageal cancer, the body is obvious. If we can't find it in time and take treatment measures, it will threaten human health in the process of continuous development of esophageal cancer. It is understood that nearly 300,000 people in China have died of esophageal cancer, which shows that diseases can also affect health. Therefore, the signal of esophageal cancer must be treated immediately to prevent local cancer from seriously threatening health. So, what is the early stage of esophageal cancer?

1, food swallowing stagnation

In the early stage of esophageal cancer, the variation degree of local cancer is not high and the symptoms are not obvious. However, some people think that there is a difference, especially when food passes through the esophagus, which may be a signal of esophageal cancer, and the development of local tumors is prone to this bad symptom. Therefore, there is always stagnation in the process of swallowing food, which can be a signal issued during the emission of esophageal cancer.

2, burning behind the sternum

After the abnormal sternum, I feel inexplicably irritable. When you are healthy, you are relaxed and there is no discomfort behind your sternum. Many people have local cancer in the pathogenesis of esophageal cancer, which may lead to burning sensation behind the sternum. If this situation already exists, it is best to check whether there is any lesion in the esophagus. If the esophagus causes cancer, it may cause obvious sternal burning sensation. Therefore, this situation cannot be ignored, and it is necessary to check and treat it immediately to avoid the seriousness of the situation.

3, swallowing food has a sense of infarction

Normal people eat food, as long as they don't wolf down their food, they are generally eaten. Some people have esophageal cancer. When esophageal cancer has become a large tumor volume, it may gradually increase, leading to esophageal compression and esophageal stenosis. Many people will feel a sense of infarction when swallowing food. If this is obvious, it can be an early signal of esophageal cancer. It is necessary to clarify the reasons. If it is esophageal cancer, it will be treated in time.

4. Sore throat

As far as the incidence of esophageal cancer is concerned, the influence of cancer has bad symptoms. There may be rubbing pain when swallowing food. Early patients may feel a sore throat, which is a mild pain. Pain is released, which is a possible signal from early esophageal cancer.

Prevention habit of esophageal cancer

The food is moldy. Mold food contains all kinds of carcinogenic toxins, so it is very important to actively digest food, especially household clothes. Usually, the water content of food can be 13% to meet the requirements of mold 13%. Once the grain becomes soft, it is necessary to select, add and add alkali frequently to reduce the intake of mycotoxins.

Strengthen the sanitary management of drinking water. It was found that the nitro content in the high incidence area of esophageal cancer was significantly higher than that in the low incidence area. Therefore, it is necessary to prevent environmental sanitation and water pollution, gradually reduce the drinking area of Dulang water and promote soil moisture. The water in the digital pond should also be disinfected, which can significantly reduce the content of nitrite anhydride in water and kill other infectious bacteria.

Beware of carcinogenic food. As the saying goes: nausea comes from the mouth. Esophageal cancer is a malignant tumor disease, which is related to people's daily eating habits. Because people eat overheated, excessive or coarse food for a long time, it is easy to damage the food tube, leading to diseases and greatly affecting the lives of patients. Through medical experiments, it is found that cancer-causing foods contain a large number of molds, which may increase the risk of cancer.

At the same time, we should avoid eating food, pickled food, rotten fruit and frying, frying, baking, frying, smoking, drinking and eating less. Cook fish and meat at low temperature. Also pay attention to how alcohol and tobacco can easily induce carcinogens, so it is best not to smoke if you don't drink. If you have a hobby of drinking, you should limit it.

Prevention of genetic factors leading to diseases. Esophageal cancer has a common family aggregation, which suggests that there is a possibility of canceration in the history of esophageal cancer, and the monitoring work in the same generation should be strengthened. Men's monitoring of patients has been strengthened, especially for 49-year-old patients who are women. Strengthen the guardianship of women, especially women aged 50-69. There should be three or two generations of cancer patients, which is a dangerous family. As a risk group, these dangerous families aged 40-69 have certain positive significance in providing regular physical examination, providing preventive drugs or vitamins and persuading them to change their habits.

Strengthen exercise. If you have little work at ordinary times, you should take part in physical activities for 3 hours every day, with at least 1 hour of exercise every week. Usually avoid weight or overweight, and the weight gain from youth to middle age should be limited to about 5 kilograms per year.
