Causes
The exact cause of Hodgkin's disease is unknown, as is true for most types of cancer. Studies have found an increased risk of Hodgkin's disease in people who have had the Epstein-Barr virus. This has led researchers to think that viral factors may play a role in causing this type of cancer. However, this is still not proven.
Other risk factors may include an HIV infection, a family history of Hodgkin's lymphoma, and previous chemotherapy or radiation exposure. People who have suppressed immune systems due to certain medications or medical conditions may also be at risk.
