Adenocarcinoma of the stomach is a type of cancer that begins in the cells lining the stomach. It is caused by a combination of genetic and environmental factors, such as smoking, alcohol, diet, and certain bacterial or viral infections.
Diagnosis of adenocarcinoma of the stomach may involve physical examination, endoscopy, imaging tests, and biopsy. Endoscopy is a procedure used to look inside the stomach to detect abnormal areas, while imaging tests can provide more detailed images of the stomach. A biopsy is the most definitive diagnostic tool to detect adenocarcinoma.
Differential diagnoses may include other types of stomach cancer, such as lymphoma or sarcoma, as well as benign conditions such as peptic ulcers or gastritis.
Treatment for adenocarcinoma of the stomach may involve surgery to remove the cancerous tumor, chemotherapy, and radiation therapy.
The prognosis for adenocarcinoma of the stomach depends on the stage of the cancer and other factors such as the patient’s overall health. Early-stage adenocarcinoma is more likely to be cured, while advanced-stage adenocarcinoma is more difficult to treat.
