Overview
B-cell prolymphocytic leukemia (B-PLL) is a very rare and aggressive type of chronic leukemia. It is characterized by the overproduction of B cells, which are a type of white blood cell that produces antibodies to help fight infections. In B-PLL, the B cells are abnormal and do not function properly, leading to a weakened immune system and an increased risk of infections.
B-PLL typically affects older adults and is more common in men than in women. The exact cause of B-PLL is unknown, but it is not believed to be hereditary. Symptoms of B-PLL can include fatigue, weight loss, and swollen lymph nodes.
Treatment for B-PLL typically involves chemotherapy, immunotherapy, or a combination of both. In some cases, a stem cell transplant may be considered.
