Treatment Protocols: Treatment options depend on the size, location, stage of the tumor, and overall health of the patient, and may include: - Surgery to remove the tumor or affected tissue - Radiation therapy to destroy cancer cells and shrink tumors - Chemotherapy to target cancer cells systemically - Targeted therapy or immunotherapy in specific cases - Supportive care to manage symptoms and maintain quality of life A multidisciplinary team approach ensures personalized treatment planning.
