The main types of cancer treatment include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Surgery involves removing the tumor, while radiation therapy uses high-energy particles or waves to destroy cancer cells. Chemotherapy employs drugs to kill rapidly dividing cells, but it can also affect healthy cells, leading to side effects. Targeted therapy involves drugs that specifically target cancer-associated molecules, minimizing damage to normal cells. Immunotherapy boosts the immune system's ability to fight cancer, offering a more personalized approach to treatment.
