Gastric Cancer Symptoms You Should Not Ignore

Gastric cancer often presents with subtle symptoms in its early stages, which can easily be mistaken for common digestive issues. However, recognizing the warning signs early can significantly improve treatment outcomes. Below are some of the most common symptoms associated with gastric cancer.

1. Persistent Abdominal Discomfort
One of the earliest and most frequent symptoms is a persistent feeling of fullness or bloating after eating, often accompanied by upper abdominal pain. This discomfort may worsen over time and can be a sign that a tumor is affecting normal stomach function. In more advanced stages, especially when cancer has spread to the abdominal cavity, fluid buildup (ascites) can cause significant swelling and discomfort in the belly.

2. Unexplained Weight Loss and Fatigue
Many gastric cancer patients experience unintentional weight loss and a general sense of weakness or fatigue. These symptoms are often linked to chronic internal bleeding caused by the tumor, which can lead to anemia. Anemia may cause dizziness, shortness of breath, and pale skin. If you're losing weight without changes to your diet or activity level, it's important to consult a healthcare professional.

3. Gastrointestinal Bleeding
Chronic bleeding in the stomach or upper digestive tract can result in black, tarry stools—often described as resembling tar or dark red matter. This condition, known as melena, is a red flag for internal bleeding and may indicate the presence of a gastrointestinal tumor. While bleeding can also be caused by less serious conditions like ulcers, it should never be ignored.

4. Difficulty Swallowing
When gastric cancer affects the lower part of the esophagus or the upper part of the stomach (cardia), it can cause a narrowing of the passage, leading to difficulty swallowing solid foods. This symptom, known as dysphagia, often signals that the cancer has progressed enough to interfere with normal digestion.

If you or someone you know is experiencing any of these symptoms for more than a few weeks, it's essential to seek medical evaluation. Early detection plays a crucial role in improving the prognosis for gastric cancer patients.
