Bone lesions are abnormal areas of bone tissue that can result from various conditions, including infections, tumors, or trauma. They can be classified as benign (non-cancerous) or malignant (cancerous) and may appear as dark or light spots on imaging studies like X-rays or MRIs. Symptoms can vary, ranging from pain and swelling to no symptoms at all. Diagnosis typically involves imaging techniques and sometimes a biopsy to determine the nature of the lesion. Treatment options depend on the underlying cause and may include monitoring, medication, or surgical intervention. Early detection is crucial for effective management of bone lesions.
