Can stomach ulcers also become cancerous? Yes, stomach ulcers can be cancerous. So, what are the signs of cancerous stomach ulcers? Let’s find out. When gastric ulcer patients over 40 years of age, the symptoms of ulcer disease suddenly change under unknown factors, the drugs with good therapeutic effect suddenly have poor therapeutic effect, and the patients have unexplained low-grade fever, generally the body temperature is below 38 degrees Celsius, which may be an early warning signal of cancer. Signal of cancerous gastric ulcer: Signal I. Change of pain nature Gastric ulcer is a satiety pain, which occurs half an hour to two hours after meal and disappears before the next meal. Once the nature of pain changes and becomes persistent and irregular abdominal pain or decreases, one should be alert to the possibility of cancer. Signal 2: Obvious emaciation Gastric ulcer patients may be easily tired, fatigue, lack of energy, loss of appetite in a short period of time, as well as indigestive diarrhea, especially diarrhea aggravated after eating meat food, nausea, vomiting, vomiting of food or dark-red food, and obstacles in digesting and absorbing nutrients in the food, and the whole body state will undergo a drastic change in a short period of time, and nutritional status will become poor, and emaciation will become obvious, and weight will drop rapidly. Rapid weight loss, anemia and persistent vomiting which is not effective in treatment and the effect of medication becomes worse, which may be the sign of cancer. Signal 3: Appearance of epigastric fullness, swelling, and palpable lumps Gastric ulcer usually does not form abdominal lumps. If a mass is felt in the fossa of the heart, it is hard, with non-smooth surface, rapidly increasing in size, painful when pressed, radiating to the back, left waist, navel, chest, precordial area, and even the back of the sternum. With the increase of mass, vomiting will be aggravated, and most of such cases are cancerous. Signal 4: Unexplainable black stool If ulcer patients have unexplainable black stool, or the result of fecal occult blood test is persistently positive, and serious anemia occurs, these phenomena indicate that gastric ulcers may be malignant into cancer. How to prevent stomach ulcer from turning into stomach cancer? First, it is better to adopt meal sharing system in the patient’s family: the infection rate and incidence of gastric ulcer are higher in people who share dishes with their family members. This is because when people share dishes and chopsticks, the Helicobacter pylori bacteria in saliva can be cross-infected and spread through dishes such as rice bowls and chopsticks. In this regard, experts suggest that patients should adopt a separate meal system when eating with family members, do not share tableware, personal bowls and chopsticks, which can effectively prevent and control H. pylori cross-infection of gastric ulcers. Second, gastric ulcer patients need to adhere to the treatment: many gastric ulcer patients do not pay attention to their own disease, do not treat or haphazardly stopping the drug, change the drug, often consume antipyretic and analgesic drugs as well as smoking and so on, these behaviors are very easy to lead to gastric ulcers recurring attacks. Experts point out that a course of treatment for gastric ulcer requires 4-6 weeks of medication, and after the pain is relieved, it still needs to be consolidated for 1-3 months, or even longer. Patients must adhere to long-term medication under the guidance of the doctor, do not stop, change drugs. Third, gastric ulcer patients should pay attention to dietary health care: patients should also do a good job of self-care, regular eating; pay attention to dietary hygiene; eating regularly, chewing and swallowing, hunger and satiety; avoid raw, cold, too spicy, too hot or strong tea, coffee and other stimulating food. Fourth, patients should pay attention to rest: gastric ulcer patients should not be overly fatigued, excessive exertion not only affects the digestion of food, but also is not conducive to the healing of ulcers. It is better for patients to adopt meal-sharing system in their families, adhere to treatment, pay attention to dietary health care, avoid over-fatigue and over-exertion, etc. These are the aspects that should be paid attention to in order to prevent gastric ulcer from becoming gastric cancer.
