Q: The current incidence of gastric cancer in the world?
Answer: East Asia has the highest incidence and mortality of gastric cancer. The world’s highest incidence of gastric cancer is South Korea, Japan is third, and Mainland China is also at the forefront. Therefore, in South Korea, the gastroscope was started at the age of 40 to check for gastric cancer; in Japan, the gastroscope was started at the age of 50. But there is no such arrangement in Taiwan, the mainland, Hong Kong and the United States. In case of anomalous phenomena, it is recommended that everyone consult their gastroenterologist for a check-up.
Ask:gastritisWhat are the symptoms?
Answer:gastritisThere are two types, one is acute gastritis and the other is chronic gastritis.
Acute gastritis often manifests as stomach pain, symptoms of peritonitis, and fever, usually caused by bacterial or viral infections. Chronic gastritis often presents with symptoms such as indigestion, nausea, bloating, and gas. But many chronic gastritis also have acute phenomena, and acute gastritis also has chronic phenomena.
Q: Will long-term gastritis evolve into gastric cancer?
A: Gastritis does not turn into stomach cancer. However, if there are abnormal cells in the stomach, such as intestinal metaplasia or intestinal metaplasia cells in the stomach, or there is a long-term bacterial infection of Helicobacter pylori, which can cause gastric cancer. So it’s not that gastritis causes gastric cancer and gastritis itself won’t become gastric cancer.
Q: What are the specific symptoms of gastric cancer?
Answer: The first is weight loss, there is no reason, and the weight begins to gradually decrease; secondly, the stomach suddenly starts to ache, after a period of pain, the appetite will also decrease and the food is relatively I feel full easily, or I want to vomit; third, I see that the stools suddenly have a slightly different color, which is black. Because when the stomach bleeds, it passes through the small and large intestines and the blood turns black. So, if you see black stools, you should pay attention and think about whether this is the possibility of stomach cancer. Especially if you don’t take iron tablets, don’t take pink medicine, don’t drink alcohol and your stools turn black, you should consult your gastroenterologist to see if you need a gastroscope to check stomach any problems.
D: It is very commonSwellingIs it a sign of stomach cancer?
Answer: Flatulence can be a warning sign of stomach cancer.Sometimes the first symptom of stomach cancer is a feeling of bloating, especially the following 7 types of people should pay attention:
Helicobacter pylori infection
atrophic gastritis
familial adenoma
intestinal metaplasia
more polyps
Partial resection of the stomach
A close relative of the family has stomach cancer
Q: Many people have some flatulence, under what circumstances is it necessary to see a doctor?
A: If you suddenly feel fuller after eating, lose weight and have an upset stomach, you should pay attention to that situation.If you want to see a gastroenterologist, you should undergo a gastroscopic examination.
D: commonGastric Cancer ScreeningWhat are the tools?
A: Now to check for stomach cancer, you need to use a gastroscope. The doctor will use a thin tube called an endoscope. It has its own lens and light source, and the doctor can view the image on a video monitor. Doctors can use gastroscopy to obtain a biopsy sample. A biopsy helps the doctor distinguish between benign (non-cancerous) and malignant (cancerous) tissue. Gastroscopes are more accurate than X-rays at finding inflammation, ulcers, and tumors in the esophagus, stomach, and duodenum.
Q: What are the risk factors for gastric cancer?
A: Risk factors for stomach cancer include:
1. There is some abnormal bacterial infection, such as bacillus pylori in the stomach, which bacteria can cause gastric cancer.
2. Smoking and drinking are also more likely to cause stomach cancer
3. If you are obese and don’t exercise enough, you are more likely to cause stomach cancer
4. In terms of diet, eating foods with more salt and more preservatives is also more likely to cause stomach cancer.
5. Eating processed meat is also more likely to cause stomach cancer.
Therefore, especially in terms of diet, processed meat containing many preservatives, preserved food, and smoking and alcohol consumption are more likely to cause stomach cancer.
Q: 90% of gastric cancer patients are infected with Helicobacter pylori. How is Helicobacter pylori infected?
Answer: Helicobacter pylori is a bacterium that is transmitted through saliva. For example, sharing meals without male chopsticks and female spoons or giving chewed food to babies are all ways of infection with H. pylori.
Q: How is Helicobacter pylori detected?
A: If one of the family members is infected with pylori, the whole family should go and check, your GP and gastroenterologist can do it for you. There are usually three ways to check:
1. Blowing, that is, you need to fast for two hours, you must first blow into a gas bag, then drink half a cup of coal 13 Helicobacter pylori blowing test solvent, about 15 minutes, then blow to another gas collection bag , the two gas collection bags are tested and analyzed to see if pylori is present.
2. Check the stool, you can find out if there is pylori.
3. For the gastroscope, the doctor will use a thin tube called an endoscope, which has its own lens and light source, and the doctor can view the images on a video monitor. You can also test the cells to see if there are any abnormal bacteria or abnormal cells. In about 10 minutes you can check for pylori.
Q: can stomach cancer be prevented? How to prevent?
Answer: Gastric cancer is preventable There are 5 main steps to prevent gastric cancer:
1. Eat less cured meat, processed meat or meat with a lot of salt, more preservatives and less smoked food.
2. Eat more fresh fruits and vegetables, not to say they have been stored for two or three nights, but those with more fiber are better.
3. Avoid sharing tools.
4. Exercise more and don’t be obese, because obesity can cause stomach cancer. If you are obese, your weight will drop.
5. It is better not to smoke, if you drink alcohol, it is better to drink less or not to drink and not to drink on an empty stomach.
Q: Can gastric cancer be detected and treated early and what is the prognosis?
A: General cancer, not just stomach cancer, no matter what type of cancer, if it can be detected early, surgery can be done and it can be cured. However, the more advanced it is, the more complicated it is and may not be cured. Therefore, if you have an abnormal sensation, such as swelling, pain, loss of appetite, weight loss, feeling full right after eating something, etc., you should have a gastroscope.
If it is relatively advanced, only radiotherapy and chemotherapy can be done before surgery, or surgery cannot be done at all. Too late and you have no effect, you can only have chemotherapy. The more advanced ones can only help you extend the time, but they cannot be cured.
Q: What is the latest treatment for gastric cancer?
A: For patients with stage 1 and 2 cancer, doctors usually recommend surgery, which usually results in good results, no more chemotherapy and no targeted therapy is needed.
For patients with stage 3 cancer, it is usually treated with a combination of chemotherapy and surgery.
For stage IV patients, the cancer has spread beyond the stomach and requires chemotherapy and sometimes targeted immunotherapy, a combination of several treatments.
Many people don’t like chemotherapy, but chemotherapy for gastric cancer is still the primary treatment method. Only 3% to 4% of gastric cancer patients do not need chemotherapy and only immunotherapy is effective. A little bit of chemotherapy is needed and now chemotherapy is no longer what people thought it was before. side effects have been reduced Many nausea, fatigue, gastrointestinal disturbances, which in the past were a common phenomenon in chemotherapy, are still present, but are not as severe as they once were.
In addition, we also encourage cancer patients to participate in clinical trials. Most clinical trials add new drugs, new technologies, and new methods of cancer research that can improve the treatments cancer patients receive from their doctors and increase the chances of a cure for cancer.
