<unk>  is the<unk>  system for lymphomas, both in Hodgkin's lymphoma (previously called Hodgkin's Disease) and Non-Hodgkin lymphoma (abbreviated NHL). It was initially developed for Hodgkin's, but has some use in NHL. It has roughly the same function as TNM<unk>  in solid tumors.
The stage depends on both the place where the malignant tissue is located (as located with biopsy, CT scanning and increasingly positron emission tomography) and on systemic symptoms due to the lymphoma ("B symptoms": night sweats, weight loss of >10% or fevers).
