What are the causes of gastric cancer?

Gastric cancer is approaching young people under 30 years old. Recent oncology statistics show that in recent years, the proportion of young people suffering from gastric cancer in my country has increased from 1.7% in the 1970s to 3.3% of the total number of gastric cancers, showing an increasing trend year by year. Let's learn about the causes of gastric cancer.

The main reason why young people suffer from gastric cancer is bad living habits.

With the increase of work pressure and the acceleration of life pace, many young people have irregular lifestyles. Especially those career-oriented young people, they either stay up too late or eat too much without knowing how to eat, which will lead to nutritional imbalance, weaken the body's resistance, and easily induce stomach problems. Irregular diet has become the primary cause of stomach cancer in young people.

Many young people like to eat pickled and smoked foods. The former has a high nitrite content, which may turn into highly carcinogenic nitrosamines when entering the stomach. The latter, due to the high temperature, will form carcinogenic substances. Hot pot and spicy hot pot are very popular among young people; and the incidence of gastric cancer in people who like to eat hot food is more than 4 times higher than that of those who do not have this habit.

At the same time, excessive smoking and drinking are also contributing to the prevalence of gastric cancer among young people.

The thiocyanate contained in tobacco can increase the synthesis of carcinogenic nitrosamines in the stomach. Excessive drinking can easily cause chronic stomach inflammation and induce gastric and duodenal ulcers. If you continue to drink too much, it will cause severe hyperplasia of the gastric mucosa and eventually lead to cancer. Many young smokers are also alcoholics; their chances of developing stomach cancer are greatly increased. Because alcoholics are twice as likely to develop stomach cancer as the general population, smokers are 2.4 times more likely, and those who are both alcoholics and smokers have a chance as high as 15.5 times!

What needs to be noted is that gastric cancer in young people is often missed or misdiagnosed. More than 70% of early gastric cancer patients do not feel any discomfort, and the symptoms of young people are even less obvious due to their stronger constitution and tolerance. Therefore, some inexperienced medical staff often label their symptoms as gastritis, ulcers, and indigestion. The missed diagnosis and misdiagnosis rate of gastric cancer in young people is as high as 27%. In other words, 1 in every 4 people is missed or misdiagnosed. Early gastric cancer is usually just a change in the mucosa. Warning signs of early gastric cancer

Gastric cancer is the most common malignant tumor in my country, and the number of deaths from gastric cancer in my country ranks first in the world each year.

When domestic patients are diagnosed, the disease is usually diagnosed at a late stage, which is an important feature of Chinese patients. How to improve the level of doctors who conduct surveys to the point where they can identify early gastric cancer is a very important issue.

Most patients with early-stage gastric cancer only experience dull pain or discomfort in the upper abdomen. The pain is not regular and worsens after meals. Some patients also experience pain similar to ulcers, which can be relieved by antacids. Early-stage patients also experience symptoms such as upper abdominal fullness and discomfort, loss of appetite, and aversion to meat and greasy food.

In my country, the current status of gastric cancer prevention and treatment is "one high and three lows": high incidence and mortality rate, low early diagnosis rate, low surgical cure rate, and low five-year survival rate.

In Japan, due to extensive screening, early gastric cancer accounts for approximately 50%-60% of newly discovered cases, 30%-40% in South Korea, and no more than 10% in China.
