[单项选择]People from large families have an increased risk of stomach cancer, suggests a study that followed more than 7,000 Japanese-American men for 28 years.
The study concluded that family size had a major influence on the development of stomach cancer linked to the bacterium Helicobacter pylori (幽门螺杆菌), and that younger siblings (兄弟，姐妹，同胞，同属) from large families were especially prone to the most common form of stomach cancer.
