What harm does gastric cancer bring

What harm does gastric cancer bring? Gastric cancer is a common disease in the oncology department. It is more common in people over 50 years old, and the male-female incidence ratio is 2:1. Its occurrence brings great harm to the patient's body and mind. Therefore, once it is discovered, it must be actively treated. The following is an introduction to the harm caused by gastric cancer.

There are obvious regional differences in the incidence of gastric cancer. The incidence of gastric cancer in the northwest and eastern coastal areas of my country is significantly higher than that in the southern region. The incidence of distal gastric cancer is high among people who have long consumed smoked, roasted, and salted foods, which is related to the high content of carcinogens or pro-carcinogens such as nitrites, fungal toxins, and polycyclic aromatic hydrocarbons in food. The risk of gastric cancer in smokers is 50% higher than that in non-smokers.

1. After gastric cancer patients become ill, their condition deteriorates very quickly, their lesions metastasize early, and their prognosis is poor. The younger the patient is, the shorter the course of the disease is. Many patients have already experienced lesion metastasis when they are diagnosed, and the metastasis range is very wide, and cachexia soon occurs.

2. Gastric cancer patients are prone to bleeding. Due to insufficient blood supply around gastric cancer tissue, ulcers are easily formed, leading to upper gastrointestinal bleeding or even perforation, and pernicious anemia is also very likely to occur.

3. Gastric cancer patients, especially young patients, have very hidden symptoms in the early stages of the disease. Their symptoms are mostly manifested as loss of appetite, indigestion, and upper abdominal pain and discomfort. These symptoms are often considered to be diseases such as peptic ulcers and gastroenteritis. Some women develop gastric cancer during pregnancy, which is often mistaken for pregnancy reactions.

4. The proliferation of gastric cancer tissue near the pylorus can cause pyloric infarction, and when the gastric cancer lesions located at the bottom of the stomach metastasize to the cardia or esophagus, it will cause infarction of the lower esophagus. These problems will in turn affect the patient's diet and other functions.

Experts have estimated that 90% of patients with advanced gastric cancer experience weight loss before dying. They usually lose more than 3 kg before they are taken seriously. Then, the weight loss becomes more obvious, and some patients lose more than 5 kg. Experts have also found that about half of the patients have symptoms such as anemia and weakness in the limbs. Therefore, if a stomach disease occurs, it is important to treat it as soon as possible to avoid it becoming a serious illness.
