Myeloma, also known as multiple myeloma, is a type of cancer that affects the plasma cells in the bone marrow. These plasma cells are responsible for producing antibodies that help fight infections. When myeloma develops, it causes an overproduction of abnormal plasma cells, which can lead to various health issues, including weakened bones, kidney problems, and a compromised immune system. Symptoms of myeloma can include bone pain, fatigue, and frequent infections. Diagnosis typically involves blood tests, imaging studies, and sometimes a bone marrow biopsy. Treatment options may include chemotherapy, targeted therapy, and stem cell transplants, aiming to manage the disease and improve the patient's quality of life.
