What are the clinical manifestations of gastric cancer?
Gastric cancer is mainly divided into: early gastric cancer and progressive gastric cancer
With the development of the disease, non-specific symptoms similar to gastritis or gastric ulcer may gradually appear, including discomfort or hidden pain in upper abdomen, acidity, belching, nausea, occasional vomiting, loss of appetite, indigestion, black stool, etc.
2.Progressive gastric cancer (i.e. middle and advanced gastric cancer) symptoms are seen as pain in the stomach area, often biting, not obviously related to eating, or similar to peptic ulcer pain, which can be relieved after eating. There is a feeling of fullness and heaviness in the upper abdomen, anorexia, abdominal pain, nausea, vomiting, diarrhea, emaciation, anemia, edema, fever and so on. Among them, pancreatic cancer mainly manifests as discomfort under the saber, pain or pain behind the sternum, accompanied by the feeling of obstruction in eating or difficulty in swallowing; cancers of fundus and subcardia often have no obvious symptoms until the tumor is huge and necrotic ulceration causes upper gastrointestinal bleeding, or the tumor infiltration extends to the pancreatic orifice causing difficulty in swallowing; cancers of gastric body are more common in the distended type, and the pain and discomfort appear later; cancers of gastric sinus less curved side are most common in the ulcerated type. When the tumor extends to the pylorus, it can cause nausea, vomiting and other symptoms of pylorus obstruction. If the cancer spreads and metastasizes, it may cause ascites, liver enlargement, jaundice and metastasis of lung, brain, heart, prostate, ovary and bone marrow, etc., and the corresponding symptoms may appear.
Supplementary: Stomach cancer usually has some other common complications, such as
1) When complicated with gastrointestinal bleeding, dizziness, palpitation, tarry stools and vomiting coffee-colored material may occur.
2) When abdominal metastasis of gastric cancer compresses the common bile duct, jaundice and clay-colored stools may occur.
(3) Combined with pyloric obstruction, vomiting, dilated gastric pattern in the upper abdomen, and vibroscopic sound can be seen.
(4) Diffuse peritonitis due to cancer perforation may result in peritoneal irritation such as abdominal muscle stiffness and abdominal pain.
5) Formation of gastrointestinal fistula, see the discharge of indigestible food.
How can prevention be carried out in daily life?
(1) Diet: The people concerned should pay attention to the usual diet, which should be based on fresh fruits and vegetables, coarse grains and less meat, so as to prevent the body fluid from being acidic and to make the body fluid alkaline by consuming “eight bases of dietary acid”. Many foods have inhibitory effects on cancer cells, such as calcium ions in food and garlic, onion and green tea containing hydrophobic base have clear protective effects, among which the protective effect of garlic is highly valued. Change the structure of diet: eat more vegetables and fruits. Increase soy foods and milk as appropriate. Reduce salt intake. Eat less or no smoked and cured foods to reduce the intake of the predecessor substances of nitrosamines. Food preservation is preferable to refrigerator refrigeration. Promote the consumption of garlic and green tea.
Change bad eating habits: avoid overeating and irregular meals; do not eat too fast, too hot, too hard.
(2) Bad habits: smoking, drinking alcohol and other bad habits should be changed.
(3) Psychological factors: nowadays, people are under too much pressure in daily life, and when this pressure is too much and not released, it will cause harm to the body.
(4) Other attention.
A. Do a good job in preventing mold and mildew removal of food and protecting the hygiene of edible water.
B. Actively treat precancerous lesions, patients with chronic stomach disease should be treated in a timely manner and regularly observed.
C. Actively protect the environment and reduce environmental pollution.
D.Census and general treatment of gastric cancer and precancerous lesions for high-incidence areas and high-risk groups.
Recently, some foreign nutrition experts found through research that eating more garlic, onions, mushrooms, cauliflower and other foods can prevent or reduce the occurrence of gastric cancer.
