Can Stomach Cancer Cause Abdominal Masses?

Stomach cancer, particularly in its advanced stages, can potentially lead to the formation of abdominal masses. When a tumor grows significantly in size, it may become palpable in the abdominal region. During a physical examination, a doctor may detect a mass in the upper abdomen, typically beneath the xiphoid process. These masses are often large, firm, and fixed in place, making them difficult to move during palpation.

If a mass is detectable on the body's surface, it usually indicates an advanced stage of cancer with considerable tumor growth. This is a critical sign that warrants further diagnostic evaluation. Comprehensive imaging tests, such as an abdominal and pelvic contrast-enhanced CT scan, are essential to determine the cancer's stage, assess the presence of metastatic lymph nodes, and check for any spread to the retroperitoneal area or liver.

Early detection and diagnosis are crucial for improving outcomes, as late-stage tumors are more challenging to treat and may require more aggressive interventions. Patients who notice any unusual abdominal swelling or lumps should seek medical attention promptly to rule out or confirm serious conditions like stomach cancer.
