<unk> , referred to as<unk> , is a rare blood cancer. It is a more aggressive, but still treatable, form of<unk> . Specifically,<unk>  is a prolymphocytic<unk>  <unk>  that affects prolymphocytes – immature forms of B-lymphocytes and T-lymphocytes – in the peripheral blood, bone marrow, and spleen. It is an aggressive cancer that presents poor response to treatment. Mature lymphocytes are infection-fighting immune system<unk> s. B-lymphocytes have two responsibilities: # Production of antibodies – In response to antigens, B-lymphocytes produce and release antibodies specific to foreign substances in order to aid in their identification and elimination phagocytes # Generation of memory<unk> s – Interactions between antibodies and antigens allow B-lymphocytes to establish<unk> ular memories, otherwise known as immunities that allow the body to respond more rapidly and efficiently to previously encountered species
