Which therapy is listed as a cancer treatment alongside radiotherapy?

• A. Chemotherapy
• B. Immunotherapy
• C. Surgery
• D. Vaccination

Answer: (A)

Cancer treatment usually combines different approaches because one method tackles the tumor in a specific way while another reaches cancer cells elsewhere. Radiotherapy targets and damages the DNA of cancer cells in a particular area, but chemotherapy circulates through the body to kill cancer cells systemically and can also make tumor cells more sensitive to radiation. That combination—chemotherapy alongside radiotherapy—is a common, well-established pairing, which is why it’s the best answer here. Immunotherapy is a newer approach that boosts the immune system to fight cancer and can be used with radiotherapy in some cases, but the classic pairing emphasized in many GCSE contexts is chemotherapy. Vaccination is mainly about prevention rather than treating an existing cancer, and surgery is a separate major modality rather than the therapy listed alongside radiotherapy in this framing.
