If there is a kind of cancer that makes people “uncomfortable”, stomach cancer is the most popular. In today’s society, with the high pace of life, many people have changed their diets and most of them are used to skipping breakfast, which leads to some stomach pains, but because “stomach pains” are too common, people often jokingly say “stomach problems? You’ve been working pretty hard lately”. But do you think that all stomach diseases are “stomach pain”? In fact, it is very wrong. As a kind of cancer, the horror of stomach cancer should be predicted even if you don’t understand it, although it is also considered as a stomach disease, but patients may not have any symptoms in the early stage, let alone the “stomach pain” that people think must exist. When you have “stomach pain”, you may have already reached the advanced stage, and this is the scary part. So what are the symptoms of early stage? 1. No matter what kind of tumor, in the early stage of cancer cell growth process, it needs a lot of nutrients and energy, so it will cause the normal tissues of the body to be unable to get nutrition, which will manifest as obvious weight loss. If the patient himself suffers from stomach disease and loses 10 kg in a month without deliberate weight loss, it should be considered whether it is caused by cancer. 2.Some patients with early stage of stomach cancer can feel a fixed mass in the right side of their upper abdomen, which is usually hard in texture and not smooth, and painful when pressed. 3.When there are certain digestive tract diseases, these symptoms will also appear, and they are more obvious in patients with gastric cancer. If the stomach tumor is in the pylorus, nausea will appear frequently, and if the tumor grows in the gastric outlet, it will emit a sour or rotten egg smell, and vomiting will also appear, and it is mostly persistent food and gastric juice. 4.More than 80% of gastric cancer patients will gradually develop epigastric pain and discomfort. In the early stage, it is similar to the symptoms of indigestion, the abdominal pain is mild and not regular, and it cannot be relieved even after eating, and as the disease progresses, the abdominal pain starts to increase frequently. Besides, if it is a tumor on the gastric sinus, the pain is regular and can be relieved obviously after eating or taking medicine. 5. As the tumor grows, it will destroy the small blood vessels in the stomach, so there will be the symptom of occult blood in the stool, but if the invaded blood vessels are larger, it will trigger vomiting blood upward and tarry black stool downward. Like other cancers, the key to prevent and treat gastric cancer is “early”, that is, early detection, early diagnosis and early treatment. According to observation and research, it is a slow process from the beginning of cancer in a certain part of stomach tissue to the appearance of certain clinical symptoms and signs, which is a gradual process from quantitative to qualitative changes. This process is called “pre-cancer” in medical science. This period is also the stage with the best treatment effect. Therefore, if patients can be detected at the early stage, it is of great significance for the subsequent treatment and there is a great hope for recovery. Instead of waiting for the miracle to happen, it is better to take the initiative to eliminate the disease at the early stage.
