There are over 70 different types of lymphoma that are organized into two groups:
- Hodgkin’s disease. This type of lymphoma is not common and mostly affects young adults. It involves large cancer cells called Hodgkin Reed-Sternberg cells. There are two main subtypes of Hodgkin’s disease: classical Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma. Classical Hodgkin lymphoma is further broken down into four sub-subtypes: nodular sclerosis, mixed cellularity, lymphocyte-rich and lymphocyte-depleted.
- Non-Hodgkin lymphoma. This type of lymphoma is more common and mostly affects older adults. It is organized into two groups: B-cell lymphomas and T-cell lymphomas. Types of Non-Hodgkin lymphoma include:
- Diffuse large B-cell lymphoma (DLBCL)
- Primary mediastinal B-cell lymphoma
- Burkitt’s lymphoma
- Follicular lymphoma
- Marginal zone lymphoma
- Mantle cell lymphoma
- Small lymphocytic lymphoma and chronic lymphocytic leukemia (SLL/CLL)
- Anaplastic large cell lymphoma
- Angioimmunoblastic lymphoma
- Peripheral T-cell lymphoma
- Cutaneous T-cell lymphoma
Lymphoma types also differ by their rate of development – some types progress slowly while others grow quickly.
