Gastric Cancer and Bowel Bleeding: What You Need to Know

Gastric cancer can indeed cause bowel bleeding, although this is not a common or defining symptom of the disease. In advanced stages, when a tumor has grown significantly and invaded nearby blood vessels, bleeding may occur. Additionally, if the tumor ulcerates or breaks open, it can lead to slow, persistent internal bleeding, which might result in blood appearing in the stool.

One of the key signs of minor bleeding is black, tarry stools, also known as melena. Some individuals may not notice these changes unless a fecal occult blood test is performed, which can detect hidden blood in the stool. Minor bleeding can often be managed with medications designed to stop bleeding and protect the stomach lining.

However, in more severe cases where bleeding is rapid and substantial, blood may accumulate in the stomach, leading to the passage of bright red blood in the stool or even vomiting blood. This type of bleeding requires immediate medical attention. In such situations, consultation with a surgeon or interventional specialist is crucial to determine the best course of action for stopping the bleed.

Treatment options vary depending on the severity and source of the bleeding. For minor cases, medication and endoscopic procedures may be sufficient. In more critical cases, surgical removal of the tumor or affected area may be necessary to control the bleeding effectively.

It's important to understand that any sign of gastrointestinal bleeding should be taken seriously. Early diagnosis and treatment can significantly improve outcomes for patients with gastric cancer. If you or someone you know experiences unexplained changes in bowel habits or signs of bleeding, seeking prompt medical evaluation is essential.
