C90.0

Clinical Causes: Genetic mutations in plasma cells Age-related genetic changes Exposure to certain chemicals or radiation Chronic immune system stimulation Family history of blood cancers

Key Symptoms: Bone pain, especially in the back or ribs Fragile bones that break easily Fatigue and weakness Unexplained weight loss Recurrent infections due to immune suppression High levels of calcium in the blood (hypercalcemia) Anemia symptoms like pale skin and shortness of breath Nausea and confusion (in severe cases of hypercalcemia)

Diagnosis Path: Diagnosing multiple myeloma involves a combination of medical evaluations and laboratory tests. These include blood tests to detect abnormal antibodies and calcium levels, urine tests for Bence Jones proteins, and bone marrow biopsies to examine plasma cell density. Imaging studies such as X-rays, MRI, or CT scans are utilized to identify areas of bone damage or lesions. Doctors also assess symptoms and medical history to reach an accurate diagnosis.

Treatment Protocols: While there is no definitive cure for multiple myeloma, several treatment strategies aim to control symptoms, slow disease progression, and improve quality of life. Common treatments include chemotherapy, targeted therapy, immunotherapy, corticosteroids, and sometimes stem cell transplants. Supportive care like bisphosphonates can help strengthen bones, and managing complications such as infections or kidney issues is essential. Treatment plans are individualized based on factors like patient health, disease stage, and response to therapy.
