Can stomach cancer cause ulcers?

Can gastric cancer cause ulcers? Gastric ulcers are benign lesions, while gastric cancer is a malignant tumor. How to correctly distinguish between the two is not only related to the choice of treatment, but also to the patient's life safety. Let's take a closer look:

Age and course of disease Gastric ulcer is more common in young and middle-aged people. 90% of patients have upper abdominal pain and it attacks periodically. Each pain can last for several days, weeks or even months, and then it will be relieved for a certain period of time, and then it will reoccur, and it will last for many years. Gastric cancer is more common in middle-aged and elderly people over 40 years old. Early gastric cancer generally does not cause obvious discomfort. But once symptoms such as upper abdominal pain appear, they will progressively worsen, the disease will develop rapidly, and the course of the disease is short.
Generally speaking, patients with gastric ulcers are in good condition, have a good appetite, respond to drug treatment, rarely have anemia, and have no swollen lymph nodes throughout the body. However, patients with gastric cancer have a poor appetite, may have no appetite in the late stage, progressively lose weight, and often have anemia. In the late stage, swollen lymph nodes can be felt above the left clavicle, and sometimes a mass can be felt in the upper abdomen.
Pain regularity: The pain of gastric ulcer is closely related to diet, that is, it starts half an hour after a meal, lasts for several hours, has a burning sensation, and then gradually disappears until the next meal. The pain can be relieved by taking alkaline drugs; the pain of gastric cancer is irregular and has nothing to do with eating. The pain can be aggravated or relieved after eating; the nature of the pain is uncertain, it can be dull or severe, and there is often a feeling of fullness; the pain in the late stage is aggravated and mostly persistent, and alkaline drugs cannot relieve it.
