Gastric Tumor and the Causes of Bleeding

When a gastric tumor develops, it can lead to internal bleeding depending on its location and depth of invasion. Tumor cells are known for their aggressive and invasive nature. If the tumor is primarily located in the gastric mucosa, it can cause mucosal damage and result in minor bleeding. This type of bleeding often presents clinically as black, tarry stools, also known as melena.

In more severe cases, if the tumor extends into the muscular layers of the stomach wall, it can invade nearby blood vessels, including veins and arteries. This invasion can lead to significant gastrointestinal bleeding, which may manifest as hematemesis (vomiting blood) or hematochezia (passing fresh blood through the rectum).

Such symptoms should not be ignored, as they can indicate advanced tumor progression. Chronic or acute blood loss can lead to complications such as anemia or even hypovolemic shock in extreme cases.

Early diagnosis and treatment are crucial in managing gastric tumors and preventing life-threatening complications like severe bleeding. Once a diagnosis of gastric cancer is confirmed, surgical resection is often recommended. The extent of the surgery depends on how far the cancer has spread. For instance, if the cancer is localized and classified as an in situ carcinoma, a partial gastrectomy may be sufficient.

Timely medical intervention significantly improves prognosis and reduces the risk of complications. Patients are advised to follow up with a specialist and undergo appropriate diagnostic tests, including endoscopy and imaging studies, to determine the best course of treatment.
