Stomach cancer�is a disease in which malignant (cancer) cells form in the lining of the stomach.
The wall of the stomach is made up of 3 layers of tissue: the mucosal (innermost) layer, the muscularis (middle) layer, and the serosal (outermost) layer. Stomach cancer begins in the cells lining the mucosal layer and spreads through the outer layers as it grows.

Causes

No one knows the exact causes of stomach cancer. Doctors often cannot explain why one person develops this disease and another does not. Studies suggest that people who eat a diet high in foods that are smoked, salted, or pickled may be at increased risk for stomach cancer. On the other hand, eating fresh fruits and vegetables may protect against this disease. People who smoke are more likely to develop stomach cancer than people who do not smoke.

Symptoms

Early stomach cancer often does not cause clear symptoms. As the cancer grows, the most common symptoms are:

• Discomfort in the stomach area
• Feeling full or bloated after a small meal
• Nausea and vomiting
• Weight loss

Most often, these symptoms are not due to cancer. Other health problems, such as an ulcer or infection, can cause the same symptoms. Anyone with these symptoms should tell the doctor so that problems can be found and treated as early as possible.

Diagnosis�
If you have a symptom that suggests stomach cancer, your doctor must find out whether it is really due to cancer or to some other cause. Your doctor may refer you to a�gastroenterologist, a doctor whose specialty is diagnosing and treating digestive problems.

The doctor asks about your personal and family health history. You may have blood or other lab tests. You also may have:

• Physical exam: The doctor checks your abdomen for fluid, swelling, or other changes. The doctor also feels for swollen lymph nodes. Your skin and eyes are checked to see if they seem yellow.
• Upper GI series: The doctor orders x-rays of your esophagus and stomach. The x-rays are taken after you drink a barium solution. The solution makes your stomach show up more clearly on the x-rays.
• Endoscopy: The doctor uses a thin, lighted tube (endoscope) to look into your stomach. The doctor first numbs your throat with an anesthetic spray. You also may receive medicine to help you relax. The tube is passed through your mouth and esophagus to the stomach.
• Biopsy: The doctor uses an endoscope to remove tissue from the stomach. A pathologist checks the tissue under a microscope for cancer cells. A biopsy is the only sure way to know if cancer cells are present.

Treatment

The choice of treatment depends mainly on the size and place of the tumor, the stage of disease, and your general health. Treatment for stomach cancer may involve surgery, chemotherapy, or radiation therapy. Many people have more than one type of treatment.

Your doctor can describe your treatment choices and the expected results. You and your doctor can work together to develop a treatment plan that meets your needs.

Cancer treatment is either local therapy or systemic therapy:

• Local therapy: Surgery and radiation therapy are local therapies. They remove or destroy cancer in or near the stomach. When stomach cancer has spread to other parts of the body, local therapy may be used to control the disease in those specific areas.
• Systemic therapy: Chemotherapy is systemic therapy. The drug enters the bloodstream and destroys or controls cancer throughout the body.
