1. There are four major symptoms in the early stage of gastric cancer
The causes of gastric cancer are complicated. So far, it can only be said that some reasons are important factors, such as Helicobacter pylori infection and bad eating habits, which have a great relationship with our eating habits, so we must pay attention to maintaining good eating habits and understanding the early symptoms of gastric cancer.
more than 1.8% patients have epigastric pain.
2. About 1/3 patients have stomach bloating, epigastric discomfort, loss of appetite, dyspepsia and pantothenic acid.
3.1/3 patients have no obvious symptoms of digestive system, but they may have unexplained weight loss, emaciation and fatigue.
4. Some patients showed symptoms such as pantothenic acid, heartburn, nausea, vomiting, belching or black stool.
In addition, it should be emphasized that men over 4 years old (alcoholics should relax to 35 years old) have slight epigastric discomfort and should be screened to achieve the purpose of early detection and early diagnosis. In the middle and late stage of the disease, the symptoms such as epigastric pain, gastrointestinal bleeding, perforation, pyloric obstruction, emaciation, fatigue, metabolic disorder and cancer spread and metastasis are more common.
2. What food is good for gastric cancer?
(1) Tomatoes
Tomatoes are rich in vitamin C, which is an important source of vitamin C, and it is not easy to be damaged during storage and cooking. Tomatoes are also rich in carotene, lycopene and vitamin B family, and lycopene is the carotenoid with the strongest oxidation resistance.
(2) Broccoli is rich
The side of broccoli is also rich in nutrients necessary for various patients, including vitamin C, carotene, calcium and potassium, etc., and it has the advantages of low fat and low calorie.
(3) Carrots
Studies have proved that if we can eat carrots every day, it can help prevent and fight cancer. Clinical research has found that if cancer patients can eat more carrots when they are undergoing chemotherapy, some side effects caused by chemotherapy can be alleviated.
3. Causes of gastric cancer
(1) Having undergone gastric surgery
Generally speaking, about 2 years after the first gastric surgery is the highest risk period of gastric cancer.
(2) Gastric polyp
Polyps are small masses growing in the gastric mucosa, most of which are benign, but adenomatous polyp, especially about 1 cm in diameter, is often a precancerous lesion.
(3) Family tumor diseases
These genetic diseases, including hereditary nonpolyposis intestinal cancer and familial adenomatous polyp, can slightly increase the risk of gastric cancer.
(4) Family history of gastric cancer
If parents or siblings have gastric cancer, the possibility of gastric cancer will increase. Therefore, if you have a family history of gastric cancer, you should consult your doctor about DNA testing.
(5) pernicious anemia
pernicious anemia is often associated with atrophic gastritis, which will slightly increase the risk of gastric cancer.
(6) Environmental factors
People who work in an environment containing a lot of smoke, asbestos and nickel for a long time will increase the risk of developing gastric cancer.
(7) Obesity
Men who are 2-25 kg above normal weight have a higher risk of gastric cancer.
(8) Living area
Gastric cancer is more common in some parts of the world, especially in Japan, China, South Korea, Latin America and parts of Eastern Europe.
(9) Economic situation
In economically poor areas, the incidence of gastric cancer is higher. This may be related to the poor hygiene habits in economically underdeveloped areas, the fact that Helicobacter pylori is more susceptible to infection, and the fact that refrigerators have not been popularized and pickled and smoked foods are often eaten.
(1) Helicobacter pylori infection
5% of gastric cancer is related to Helicobacter pylori infection, and about 6% of people in China are infected with Helicobacter pylori. People infected with Helicobacter pylori are more likely to develop gastric cancer. Of course, most infected people do not develop gastric cancer. Researchers believe that personal genetic factors also make some people more likely to develop gastric cancer.
