Which cancer type is known for spreading to the peritoneum, liver, and lungs?

Pancreatic cancer is known for its aggressive behavior and propensity to spread or metastasize to various organs, including the peritoneum, liver, and lungs. One reason for this is the anatomical positioning of the pancreas and its proximity to other vital structures and organs. When pancreatic cancer develops, it can invade local tissues or spread hematogenously (via the bloodstream) to distant sites. Peritoneal spread can occur early in the disease process due to the pancreatic cancer's close association with the peritoneal cavity, which houses various organs such as the intestines and liver, facilitating metastasis to these areas. Additionally, the liver serves as a common metastatic site for many abdominal cancers, including pancreatic cancer, because of its rich blood supply and direct venous drainage from the gastrointestinal tract. Furthermore, the lungs are frequently involved in advanced stages of cancer, as they are another primary site for the spread of cancerous cells through circulation.

Understanding these patterns helps in recognizing the aggressive nature of pancreatic cancer and the importance of early detection and treatment.
