Gastric adenocarcinoma is a type of stomach cancer that begins in the inner lining of the stomach. Abnormal cells multiply rapidly to form a tumor. Early stages often have no symptoms, so prompt detection improves treatment options and outcomes. The ICD-10 code for this condition is C16.
He reviews your symptoms, personal and family history of stomach issues, lifestyle factors (like smoking or alcohol use), and any prior H. pylori infections.
Routine blood work evaluates overall health, checks for anemia, and rules out other causes of digestive symptoms.
An endoscope is used to inspect the stomach lining directly; small tissue samples are taken (biopsy) to confirm the presence and type of cancer cells.
CT scans of the abdomen and pelvis determine if the tumor has spread beyond the stomach to lymph nodes or other organs.
