Non-Hodgkin lymphoma

Non-Hodgkin lymphoma (NHL) is one of the most common hematologic malignancies worldwide. NHL includes malignant tumors of the lymphoid tissues variously resulting from the clonal growth of B cells, T cells and natural killer cells. NHL can be broadly classified based on the type of lymphocyte involved: B lymphocyte (B cell) or T lymphocyte (T cell) and is further classified by other factors, including whether it is aggressive or indolent. Aggressive NHL is fast-growing disease. It mainly includes mantle cell lymphoma, diffuse large B-cell lymphoma, Burkitt's lymphoma, lymphoblastic lymphoma and peripheral T-cell lymphoma. On the other hand, indolent NHL is slow-growing disease. It mainly includes follicular lymphoma, cutaneous T-cell lymphoma, lymphoplasmacytic lymphoma and MALT lymphoma.
