Gastric Tumor Symptoms and Insights

Gastric tumors can present a variety of symptoms depending on whether they are benign or malignant. Common symptoms associated with malignant gastric tumors, especially in advanced stages, include bloating, abdominal pain, loss of appetite, black tarry stools, weight loss, early satiety, and the presence of an abdominal mass. Among these, black stools are considered the most specific indicator of malignancy.

Benign gastric tumors such as submucosal tumors — including gastric leiomyomas, gastrointestinal stromal tumors (GISTs), gastric neuroendocrine tumors, ectopic pancreas, and gastric lipomas — typically do not cause noticeable symptoms. These types of tumors are often discovered incidentally during endoscopic examinations.

On the other hand, malignant gastric tumors mainly consist of gastric cancer, gastric malignant lymphoma, and malignant neuroendocrine tumors. In the early stages, these cancers may not produce clear or severe symptoms. Patients might experience mild discomfort such as bloating, stomach pain, or heartburn.

Understanding the differences between benign and malignant tumors is essential for early detection and appropriate treatment. While benign tumors are generally asymptomatic, malignant growths can lead to serious health complications if not diagnosed early. Therefore, it is important to consult a healthcare professional if persistent digestive symptoms occur.
