A cancerous tumor that forms in tissues lining the stomach. Tumors in the stomach can be benign (not cancerous) or malignant (cancerous). Benign tumors are not as harmful as malignant tumors and typically do not grow back once removed from the body.
Stomach cancer usually begins in cells in the inner layer of the stomach. Over time, the cancer may invade more deeply into the stomach wall. Eventually, a stomach tumor can grow through the stomach’s outer layer into nearby organs, such as the liver, pancreas, esophagus, or intestine.
As cancerous tumors in the stomach grow, an individual will start to experience certain symptoms associated with the disease. Such symptoms may include pain in the stomach area, nausea, difficulty swallowing and weight loss.
Treatment procedures for gastric carcinoma depend heavily on the size and location of the tumor. In general, the procedures your doctor will likely suggest are surgery, radiation therapy or chemotherapy.
