Description
The majority of stomach cancers are adenocarcinomas, which originate from glandular cells in the stomach lining. Other less common types include gastrointestinal stromal tumors (GISTs), lymphomas, and carcinoid tumors. Each subtype behaves differently and requires distinct diagnostic and treatment approaches.
Risk factors for stomach cancer include chronic infection with Helicobacter pylori, long-term inflammation of the stomach (gastritis), smoking, heavy alcohol use, a diet high in salted, smoked, or processed foods, and a family history of gastric cancer. Certain genetic conditions and previous stomach surgery can also increase risk.
Early symptoms are often subtle and may resemble common digestive issues. These can include persistent indigestion, bloating, loss of appetite, mild nausea, early satiety (feeling full quickly), and vague upper abdominal discomfort. In more advanced stages, symptoms may include weight loss, vomiting, difficulty swallowing, or gastrointestinal bleeding.
Diagnosis typically involves endoscopy, where a flexible tube with a camera is used to examine the stomach lining and obtain biopsy samples. Imaging tests such as CT scans, PET scans, and endoscopic ultrasound help determine the depth of tumor invasion and whether the cancer has spread to nearby lymph nodes or distant organs.
Treatment depends on the stage and type of stomach cancer and may include surgery, chemotherapy, radiation therapy, targeted therapy, or immunotherapy. Surgical removal of part or all of the stomach (partial or total gastrectomy) is often required for localized disease, while advanced cases typically require systemic therapies.
Advances in molecular profiling have improved treatment personalization, allowing clinicians to identify biomarkers such as HER2 status and PD-L1 expression that guide targeted and immunotherapy options. These developments have expanded treatment possibilities for patients with advanced or metastatic disease.
Living with stomach cancer often involves significant dietary adjustments, nutritional support, and careful symptom management, especially after surgery. Patients may need long-term follow-up to monitor for recurrence and manage complications such as weight loss or vitamin deficiencies. With early detection and comprehensive care, many individuals experience improved survival and quality of life.
