Hodgkin disease is a type of lymphoma and accounts for approximately 1% of all cancers. HD spreads contiguously and predictably along lymphatic pathways and is curable in 85 to 95% of cases, depending on its stage and sub-type.

The disease is characterized by the presence of Reed-Sternberg cells (considered to be a type of B cell).

Hodgkin's disease is usually almost entirely confined to the lymph nodes.
