Eat more fresh vegetables can help prevent stomach cancer. (Gettyimages) the global annual new cases of gastric cancer, 42% from the number of new cases in China, the number of nearly 400 thousand people; an average of about 2 to 3 minutes, 1 Chinese died of stomach cancer, but the detection rate of early gastric cancer in China is only about 10% above is in the hope of a reporter from the Ministry of health with the China anticancer association organized the "special informed: Gastric Cancer Awareness Month" conference data, these data again shows that China's grim situation of gastric cancer.
In the treatment of gastric cancer, at present, the medical profession has a new discovery - about 22% of gastric cancer patients with HER2 (human epidermal growth factor receptor 2) positive. HER2 is a dangerous signal, indicating a shorter survival time, cancer is more likely to relapse. To this end, experts recommend that patients with gastric cancer should be HER2 testing in order to develop more targeted treatment.

Every 2 to 3 minutes, there are 1 Chinese people died of stomach cancer
Gastric cancer is one of the most common cancers in the world, and is the second most common cancer in china. According to statistics from the WHO cancer control program, the number of patients who die of cancer every year in the world is as high as 7 million, of which the number of patients with gastric cancer accounts for about 700 thousand. Chinese Anticancer Association Committee, director of the Specialized Committee and gastric cancer of gastrointestinal tumor, Tianjin Cancer Hospital professor Liang Han introduced: "934000 new cases every year, 42% (400 thousand) of the number of new cases in our country, the morbidity and mortality of gastric cancer in China is more than 2 times the world average, about every 2 ~ 3 minutes, 1 Chinese died of stomach cancer. Compared with other countries, China's stomach cancer situation is more severe."
The incidence of gastric cancer in men is 1.5 to 2.5 times that of women. In recent years, the incidence and mortality of gastric cancer in our country have a slight decline. But it is worth noting that this decline is caused by men, on the contrary, women's stomach cancer incidence and mortality rates are on the rise.
The early detection rate of gastric cancer in China is very low
The same as the high incidence of gastric cancer in China, the early detection rate of gastric cancer is far worse than Japan and South korea." Liang Han said, the Japanese government has invested in over 40 years old population census of gastric cancer from 1963 onwards, the detection rate of early gastric cancer in Japan more than 60%; screening in the Korean population over the age of 40, the detection rate of early gastric cancer is about 40%; while in China more than 90% people hospitalized gastric cancer cases is advanced to only medical treatment.
Positive out of the clutches of young patients with gastric cancer"
In addition to improve the early diagnosis rate, the younger trend of gastric cancer is also very worthy of attention.
The peak age of gastric cancer is 50 to 80 years old, but this does not mean that gastric cancer is far away from young people. From the clinical point of view, the incidence of gastric cancer in young people increased rapidly. In the past 5 years, 19 to 35 year olds the incidence of gastric cancer doubled that of 30 years.
The removal of gastric cancer the most common high-risk factor, serious lack of sleep, diet, work and psychological pressure, and stomach discomfort or Helicobacter pylori infection of the stomach is more and more not to regard it as right, the main factors of young people suffering from stomach cancer." Professor Xu Ruihua, vice president, deputy director of Zhongshan University Guangzhou cancer prevention center stressed that young people suffering from gastric cancer are often more malignant, more rapid development, coupled with the diagnosis of gastric cancer often has come in late, poor treatment effect.
Gastric cancer is also divided into "Yin" and "Yang""
In gastric cancer, there are yin and yang. The study found that about 22% of patients with gastric cancer were positive for HER2 (human epidermal growth factor receptor 2) and the rest were negative.
If the HER2 is positive, this is a dangerous signal, which indicates that the patient's survival time is shorter and the cancer is more likely to recur. In other words, HER2 positive cancer patients whose cancer is more difficult and require more powerful "ammunition" storm on the.
In order to seize the best opportunity for treatment, Liang suggested that patients with gastric cancer were detected by HER2, in order to investigate the deterioration of faster cancer.
At present, HER2 detection has been widely used in many hospitals, the most common immunohistochemical method (IHC) in hospitals above two can be carried out, as long as 80 ~ 100 yuan / times, and has entered the health insurance directory.
Special symptoms should be treated as soon as possible
Early gastric cancer without typical symptoms, even bloating, loss of appetite, nausea and vomiting and other symptoms, but also easy to be neglected as a general stomach, this is an important reason for patients to early detection. Due to the huge population in China, it is not realistic to carry out the screening and screening of gastric cancer in the population. To this end, Liang suggested that high-risk groups should be regularly screened consciousness, every two years to do a gastroscopy.
The expert reminds, once appear, abdominal discomfort, chest pain, postprandial fullness, loss of appetite, weight loss, weakness, indigestion and vomiting often overnight without bile juice, or black stool tarry and other symptoms, should as soon as possible, do not delay.
Garlic can prevent gastric cancer?
The cause of gastric cancer is still unclear. It is generally believed that it is related to the age, sex and heredity of the patients, and some chronic benign gastric diseases, such as gastric polyps, gastric ulcer, chronic atrophic gastritis and pernicious anemia, also have the possibility of developing into gastric cancer. In addition, the deterioration of food or cooking, geographical conditions, air, water, environmental pollution, dust and toxicant exposure is also associated with the incidence of gastric cancer.
Liang said in particular, a variety of studies suggest that gastric cancer and eating habits have a direct relationship. He explained that the high incidence of gastric cancer in Japan, but the third generation of Japanese immigrants to the United States to reduce the incidence of gastric cancer in the United States and the United States, which shows that gastric cancer and diet and living environment. Salted food, pickled food, moldy food are considered to be a risk factor for gastric cancer.
Have a preventive effect of raw garlic
What kind of food to eat to prevent gastric cancer? Garlic! Liang Han said that eating garlic is likely to be a protective factor against gastric cancer. One of the areas of high incidence of gastric cancer in Shandong County, Linqu Province, but not far away from the county, the death rate of gastric cancer is only 1/10 of Linqu county. After investigation, the residents of the county often eat garlic, garlic intake per capita in Linqu 6 times. The main effective component in garlic is allicin, but Liang Han stressed that it must be eaten raw garlic have a preventive effect, eat cooked or pickled food effect.
In addition, eat more fresh vegetables, strengthen carotene and vitamin C intake, also help to prevent stomach cancer.
Who is a high-risk population of gastric cancer?
The infection of Helicobacter pylori
The male, especially more than normal weight 20 ~ 25 kg men
- between the ages of 50 to 80 years old
- eat salted pickled vegetables or smoked meat and fish and other foods
The gastric surgery, gastric polyp
The family history of gastric cancer, tumor disease
The malignant anemia
The blood type A
The work with large amounts of dust, asbestos and nickel environment for a long time
