Nowadays, esophageal cancer has become a kind of malignant tumor that has to be concerned, because more and more people suffer from this kind of malignant tumor. The esophagus is the throat of the human body. When the body is uncomfortable and wants to spit out food, it must pass through the esophagus; When we eat and swallow, we also pass through the esophagus, which is enough to show that the esophagus is one of the most important parts of the human body.

What are the manifestations of esophageal cancer

There are no obvious symptoms in the early stage of esophageal cancer. Some people will feel choking and foreign body sensation when swallowing food, and pain like burning, acupuncture or traction friction behind the sternum.

The typical symptom of esophageal cancer is progressive and aggravated dysphagia. First, it is difficult to swallow dry food, then it is semi liquid food, and finally water and saliva cannot be swallowed.

Causes of esophageal cancer

1、 Hot food: Eating hot food and drinking hot tea often is not conducive to the health of the esophagus. According to research, eating hot food for a long time will promote the occurrence of cancer, which will give cancer cells a very good development environment.

2、 Nitrosamines: Nitrosamines are highly carcinogenic compounds, and more than 10 of more than 100 nitrosamines can cause esophageal cancer. This kind of material is not uncommon and is within reach in daily life.
For example, hair dyes, bacon, cigarettes, stale fruits, overnight meals and rotten vegetables contain nitrosamines.

3、 Genetic factors: the relationship between heredity and esophageal cancer cannot be excluded from the pathogenic factors of esophageal cancer, and esophageal cancer patients have obvious family aggregation.

Be careful when these situations occur

Early esophageal cancer will send signals to the body. Once your body has such a situation, you must pay attention to it! Grasp the best opportunity to treat the disease, and try to find, diagnose and treat it as early as possible.

• Slight choking sensation when swallowing food: It is very common in daily life, such as tonsil inflammation or bronchial inflammation when the patient has a cold. But if this happens suddenly, it may be the signal of precancerous lesions.

• Discomfort near the posterior sternal fossa when eating: When eating, there is a sense of friction, tingling, and foreign body near the posterior sternal fossa. The signal of esophageal cancer usually appears during eating or when the patient swallows.

• There will be a sense of stagnation when food enters the esophagus: during eating, there will be a sense of stagnation when food enters the esophagus. If the patient's esophagus has precancerous lesions, there will be tumors in the esophagus, which will make the space in the esophagus smaller, and the patient will be blocked by these tumors when swallowing food, resulting in a sense of stagnation.

• Strong discomfort in the back of the sternum: the signal of esophageal cancer is also very strong when the patient does not eat. If you feel the tightness in the back of the sternum and it is difficult to sit and stand, you must not simply deal with it or take some medicine at will. You must go to the hospital in time to find out the cause and actively curb the deterioration of the disease.

How to prevent esophageal cancer

1. Develop good eating habits and avoid eating too hot food. Eat less, eat more, chew slowly, avoid moldy rice, noodles, peanuts and other foods and overnight meals, and reduce the intake of strong tea, coffee, liquor and other stimulating foods.

2. Reduce the intake of pickled and smoked foods.

3. Quit smoking and drinking. The content of nitrosamines in tobacco is very high, which is closely related to esophageal cancer. Tobacco contains not only nicotine, a toxic substance, but also more than 50 kinds of harmful substances. The harm to the human body is very extensive. The human mouth, esophagus, stomach, pancreas and heart will be damaged by the habit of smoking for a long time. This kind of damage is irreversible.

4. Check your body regularly. Cancer is closely related to heredity, which requires friends with family history to keep the good habit of checking your body regularly, predict disease earlier than cancer, and protect your health and that of your family.
