T-cell acute lymphoblastic leukemia (T-ALL) is a type of blood cancer that starts from immature T cells, a type of white blood cell that normally helps control the immune response and fight viruses. These immature, abnormal cells are called lymphoblasts. In T-ALL, the lymphoblasts accumulate in the bone marrow and blood, crowding out normal blood …

Classic follicular lymphoma is a type of blood cancer that starts in B cells — specialized white blood cells that normally help the body fight infection. It is the second most common lymphoma in adults and is considered an indolent, or slow-growing, cancer. Most people are diagnosed when they notice a painless lump or swelling, …

EBV-positive diffuse large B cell lymphoma (EBV-positive DLBCL) is an aggressive blood cancer that starts in B cells — the white blood cells that help the body fight infections by producing antibodies. It is a specific subtype of diffuse large B cell lymphoma defined by the presence of Epstein-Barr virus (EBV) inside the lymphoma cells. …

What is plasmablastic lymphoma? Plasmablastic lymphoma (PBL) is a rare and aggressive type of immune system cancer and a type of non-Hodgkin lymphoma (NHL). The tumour is made up of plasma cells that arose from B cells. What are the symptoms of plasmablastic lymphoma? The symptoms of PBL depend on where in the body the …

Aggressive B cell lymphoma is a term used to describe a group of immune system cancers made up of cells called B cells. Although this is considered enough to establish a formal diagnosis, additional tests might be needed to refine how best to group or subclassify the disease. What types of B cell lymphoma are …

Extranodal NK/T cell lymphoma is a rare, fast-growing cancer of the immune system. It starts in either natural killer (NK) cells or T cells, two closely related types of white blood cells that normally identify and destroy infected or abnormal cells. The word “extranodal” means that the lymphoma typically begins outside the lymph nodes, most …

ALK-negative anaplastic large cell lymphoma (ALCL) is a type of cancer that starts in T cells, which are specialized white blood cells that help the body fight infections. Because it begins in immune system cells, it is classified as a non-Hodgkin lymphoma (NHL). This disease can start in many different parts of the body. Common …

ALK-positive anaplastic large cell lymphoma (ALCL) is a type of cancer that starts in T cells, which are specialized white blood cells that normally help the body fight infections. Because it develops from immune cells, it is classified as a non-Hodgkin lymphoma (NHL). This disease most often involves lymph nodes, but it can also appear …

Extranodal marginal zone lymphoma of mucosal-associated lymphoid tissue — also called MALT lymphoma, or EMZL — is a slow-growing (indolent) blood cancer that starts in B cells, the white blood cells that help the body fight infections. The word “extranodal” means that the lymphoma arises outside the lymph nodes, in the tissues of various organs. …

Small lymphocytic lymphoma (SLL) is a slow-growing (indolent) blood cancer that starts in B cells — the white blood cells that help the body fight infections. It is defined by the accumulation of abnormal small B cells in the lymph nodes, spleen, bone marrow, and other tissues. SLL is biologically identical to chronic lymphocytic leukemia …
