Early symptoms of gastric cancer that may be overlooked
Early symptoms of gastric cancer that may be overlooked. Gastric cancer is one of the main malignant diseases threatening human health. The cause of gastric cancer is not yet clear, and experts have different opinions on its influencing factors.
What caused the occurrence of gastric cancer?
The cause of gastric cancer is not yet clear, and experts have different opinions on its influencing factors. From the current clinical research, the following are the factors that affect gastric cancer:
Smoking: It may be one of the causes of cancer, but the mechanism is still unclear.
Like to eat pickled foods: Salt itself does not cause cancer, but high concentrations of salt will destroy the mucous layer of the gastric mucosa, accelerate the damage of gastric acid to cells, and increase the carcinogenic effect. A large number of nitroso groups in pickled foods are destroyed, especially pickled vegetables, not only high salt, nitroso groups are destroyed, but also low in vitamin C, so it is closely related to gastric cancer.
Irregular diet: Overeating, eating fast, often eating hard and hard food, and eating irregularly will increase the burden on the stomach and cause chronic gastritis, thereby increasing the risk of gastric cancer. In addition, long-term drinking, spicy, hot food will increase the risk of gastric cancer.
Fried and smoked food: Food will lose a lot of nutrients when it passes through high temperature, and it will produce a kind of “polycyclic aromatic hydrocarbon compound”, which has a serious carcinogenic effect.
Helicobacter pylori infection: Helicobacter pylori can induce gastric mucosal inflammation, leading to the regeneration of gastric mucosal epithelial cells and promoting the occurrence of gastric cancer.
Family history of tumor: The incidence of gastric cancer has obvious family clustering.
What are the early symptoms of gastric cancer?
There can be no symptoms at all in the early stage of gastric cancer, most of which are some relatively vague feelings.
Fullness and discomfort: Inexplicable swelling, without obvious incentives, it mostly appears when it is quiet, and disappears when activities and spirits are dispersed.
Pain: It is mainly intermittent pain, which will gradually increase and continue. Although the pain is tolerable, it is not easy to relieve or reappears after relief.
Anorexia acid reflux: No interest in the foods they like, especially meat and greasy foods, accompanied by acid reflux or indigestion.
Occult blood is positive: clinical laboratory stool results suggest that it is positive for occult blood or melena.
Fatigue and weight loss: Unexplained fatigue, weight loss or anemia: The weight loss is obvious, and it can lose 3~5 kg within 2~3 months.
Pain changes: The original pain pattern has changed: In the past, patients may suffer from fasting pain or pain after eating, but they have changed recently.
