When you discover a lump or experience persistent pain in your bones, joints, or surrounding tissues, concerns about musculoskeletal tumors naturally arise. Understanding the difference between benign vs malignant musculoskeletal tumours can help ease anxiety and guide you toward appropriate medical care. While the word "tumor" often causes alarm, many musculoskeletal tumors are benign and pose no serious threat to your health. Musculoskeletal tumors affect the bones, muscles, tendons, ligaments, and other connective tissues that support your body's structure and movement. These growths can develop in anyone, though certain types are more common in specific age groups. The distinction between benign vs malignant musculoskeletal tumours lies primarily in their behavior, growth patterns, and potential to spread throughout the body.
