Gastric Cancer Symptoms and Warning Signs

Gastric cancer, also known as stomach cancer, originates from the epithelial lining of the stomach. In its early stages, it often presents with no clear or specific symptoms, which makes it difficult to detect. Some individuals may experience mild symptoms such as nausea, vomiting, or discomfort similar to peptic ulcer disease. These signs are often mistaken for common gastrointestinal issues like chronic gastritis, leading many to overlook the possibility of something more serious.

As the cancer progresses and the tumor grows, more noticeable symptoms may appear. These symptoms typically arise when the tumor begins to interfere with normal digestive functions or spreads to other parts of the body. Below are some of the most common indicators of advanced gastric cancer:

Loss of appetite and unexplained fatigue are often among the first noticeable signs. Patients may feel unusually tired and lose interest in food, leading to unintentional weight loss.

Swollen lymph nodes in the left clavicle area can be a sign of lymph node metastasis. This symptom may be detected through physical examination and should be evaluated by a medical professional.

Pain in the upper abdomen and significant weight loss are the most frequent symptoms in more advanced stages of stomach cancer. The pain may be persistent and worsen over time.

Bleeding in the digestive tract can occur, which may result in vomiting blood or passing black, tarry stools. Blood in the stool or vomit is a serious symptom and requires immediate medical attention.

In cases of cancer located near the gastroesophageal junction, difficulty swallowing and chest pain behind the breastbone may develop. This can lead to progressive dysphagia, making it increasingly hard to eat solid foods.

Tumors near the pylorus can cause obstruction of the digestive tract, leading to bloating, nausea, and vomiting after meals.

Finally, in more advanced cases where the cancer has spread beyond the stomach, symptoms such as jaundice, ascites (fluid buildup in the abdomen), and widespread organ dysfunction may appear. These are signs of metastatic disease and require comprehensive evaluation and treatment planning.

If you or someone you know experiences any of these symptoms persistently, especially unexplained weight loss, difficulty eating, or signs of internal bleeding, it is important to consult a healthcare provider for proper diagnosis and care. Early detection significantly improves the prognosis for gastric cancer patients.
