What Is Stomach (Gastric) Cancer?

Stomach cancer, also called gastric cancer, begins in the lining of the stomach. It typically starts in the inner layer and can grow through the stomach wall, sometimes spreading to other parts of the body.

What Causes It?

Stomach cancer develops from changes in the DNA of stomach cells. While the exact cause isn’t always known, risk factors may include:

• Chronic stomach inflammation or infection (like H. pylori)

• Family history

• Smoking

• Diet high in salty or processed foods

• Obesity and low intake of fruits and vegetables

How Is It Diagnosed?

Diagnosis may include:

• Imaging (CT, PET, MRI, ultrasound)

• Endoscopy (a small camera to view the stomach)

• Blood tests

• Biopsy to confirm cancer

These tests help guide your care plan.

Signs and Symptoms

Symptoms may include:

• Abdominal pain or discomfort

• Bloating or feeling full quickly

• Nausea or vomiting

• Unexplained weight loss

• Fatigue or anemia

• Blood in stool or vomit

If you notice any of these, it’s important to speak with your doctor.

Treatment Options

Treatment depends on the stage and may include:

• Surgery

• Chemotherapy

• Radiation therapy
