Non-Hodgkin lymphomas (NHLs), also known as non-Hodgkin disease are diverse group of blood cancers that include any kind of lymphoma except Hodgkin's lymphomas. Non-Hodgkin’s lymphoma (NHL) consists of a group of more than 20 different malignant lymphoproliferative diseases that originate from lymphocytes. NHL was the fifth most common cancer in Ireland, accounting for 3.4% of all malignant neoplasms, excluding non-melanoma skin cancer, in women and 3.6% in men (Table 8.1).The average number of new cases diagnosed each year was approximately 354 in women and 392 in men. During 1995-2007, the number of new cases diagnosed increased by approximately 3% per annum overall.
While some patients with non-Hodgkin's lymphoma can be successfully treated, for many the most-effective course is to keep knocking back the disease over a period of many years. In these cases, personalized long-term care is especially important.. When non Hodgkin lymphoma is diagnosed a team of doctors and other professionals work together to decide on the best treatment for each person. The main types of treatment for NHL are chemotherapy, radiotherapy, and biological therapy. Some people may have surgery. Sometimes high dose chemotherapy with a stem cell transplant may be used to try to increase the chance of curing NHL.
