Stomach Cancer
Introduction
A Helicobacter pylori Infection is a major risk factor for stomach cancer. Vague abdominal discomfort, weight loss, and weakness are some typical symptoms. Diagnosis includes endoscopy and biopsy. Surgery is done to eliminate the cancer or relieve symptoms. The survival rate is low because the cancer tends to spread early to other sites. About 95% of Stomach cancers are adenocarcinomas. Adenocarcinomas of the stomach originate from the glandular cells of the stomach lining. Worldwide, stomach cancer is the second most common cancer. It is far more common in Japan, China, Chile, and Iceland. In these nations, screening programs are an important means of early detection. For unknown reasons, adenocarcinoma of the stomach is becoming less common in the United States. In 2023, stomach cancer will occur in an estimated 26,500 people and will cause an estimated 11,130 deaths, making stomach cancer the 16th most commonly diagnosed cancer and the 17th leading cause of cancer-related death in the United States. In the United States, stomach cancer is most common among Black, Hispanic, and American Indian people. As people age, the risk of developing stomach cancer increases—more than 75% of people are over age 50.
