Gastric cancer, also known as stomach cancer, is a type of cancer that develops in the lining of the stomach. Symptoms of gastric cancer can include persistent indigestion, abdominal pain, heartburn, nausea, vomiting, difficulty swallowing, and weight loss. Diagnosis is usually made through a combination of imaging tests, such as X-rays and CT scans, and biopsies, which involve taking a small sample of tissue from the stomach for examination. Treatment for gastric cancer typically involves surgery, chemotherapy, and radiation therapy. Surgery involves removing the tumor, while chemotherapy and radiation are used to destroy any remaining cancer cells.

Esophageal cancer is a type of cancer that affects the lining of the esophagus. Symptoms may include difficulty swallowing, weight loss, chest pain, and coughing up blood. Diagnosis is typically made by performing an endoscopy and biopsy. Treatment may include surgery, radiation therapy, and chemotherapy. Early diagnosis and treatment can improve the prognosis for those affected by esophageal cancer.
