Yes, liver metastases are indeed common. The liver is a large organ responsible for filtering blood. Consequently, cancer cells circulating in the bloodstream often become trapped within the liver, where they can continue to proliferate. This phenomenon is particularly prevalent with cancers originating in the digestive system, such as the colon, stomach, pancreas, bile ducts, and small intestine, as blood from these organs flows directly to the liver. Furthermore, the liver is also a frequent site for metastases from other primary cancers, including breast cancer, lung cancer, and lymphomas.
