Muscle tumors are abnormal growths that can develop in the muscle tissue of the body. They can be benign (non-cancerous) or malignant (cancerous) and may occur in various types of muscle, including skeletal, smooth, and cardiac muscle. Symptoms can vary depending on the tumor's size and location, often causing pain, swelling, or limited movement. Diagnosis typically involves imaging tests like MRI or CT scans, and a biopsy may be performed to determine the tumor's nature. Treatment options include surgery, radiation therapy, and chemotherapy, depending on whether the tumor is benign or malignant and its overall impact on health.
