Tumor treatment involves various methods aimed at eliminating or controlling the growth of tumors, which are abnormal cell masses. Common approaches include surgery, where the tumor is physically removed, and radiation therapy, which uses high-energy rays to target and kill cancer cells. Another key method is chemotherapy, involving drugs that attack rapidly dividing cells, including cancerous ones. Additionally, immunotherapy helps the body's immune system recognize and fight tumors. The choice of treatment depends on factors like tumor type, location, and the patient's overall health.
