4. Loss of appetite
5. Difficulty breathing (if tumor is in the chest)
Diagnosis:
1. Physical examination
2. Imaging studies (e.g., X-rays, CT scans, MRI)
3. Biopsy or fine-needle aspiration
Treatment:
1. Surgery
2. Chemotherapy
3. Radiation therapy
4. Combination therapy
Prognosis:
1. Varies depending on sarcoma type, stage, and location
2. Generally, early detection and treatment improve outcomes
