What is (are) Mantle cell lymphoma ?
Mantle cell lymphoma (MCL) belongs to a group of diseases known as  non-Hodgkins lymphomas (NHL), which are cancers that affect the the lymphatic system (part of the immune system). MCL accounts for 6% of all non-Hodgkin lymphomas and is mostly found in males during their early 60s. Lymphocytes, which are white blood cells that make up the lymphatic system. There are two main types: B-lymphocytes (B-cells) and T-lymphocytes (T-cells). Mantel cell lymphoma is a B-cell lymphoma that develops from cancerous B-cells within a region of the lymph node known as the mantle zone. Although mantle cell lymphomas are slow-growing cancers, at the time of diagnosis, they are usually widespread in the lymph nodes and require intensive treatment because they can become lethal within a short period of time.
