Plasma Cell Neoplasm is a type of cancer that originates from plasma cells, which are a kind of white blood cell responsible for producing antibodies. This condition can lead to the overproduction of abnormal antibodies, resulting in various health issues. The most common form of plasma cell neoplasm is multiple myeloma, which affects the bone marrow and can cause bone pain, anemia, and kidney problems. Diagnosis typically involves blood tests, imaging studies, and bone marrow biopsies to assess the presence of abnormal plasma cells. Treatment options may include chemotherapy, radiation therapy, and targeted therapies to manage symptoms and control the disease. Early detection and intervention are crucial for improving outcomes.
