5. Epidemiology of Non-Hodgkin Lymphoma
The American Cancer Society estimated that in 2019, there were about 74,200 new cases of non-Hodgkin lymphoma (NHL). Since the early 1970s, it has been observed that the incidence rates of NHL have almost doubled. However, some of these increased rates can be attributed to improved diagnostic techniques and better medical care.
NHL is the most common hematopoietic neoplasm where it represents about 4.2% out of all cancer diagnoses and is 7th in ranking in terms of frequency among all cancers. Generally, NHL is diagnosed around ages 65 to 74, except small noncleaved lymphomas and high-grade lymphoblastic lymphomas, which are more often observed in young adults and children.
