Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (B), (D) and (E) only
(A) Vaccination — Incorrect. A vaccine gives immunity against a pathogen before infection, as for polio or hepatitis B. It is not one of the approaches for treating cancer.
(B) Surgery — Correct. The tumour is removed by an operation.
(C) Physiotherapy — Incorrect. Physiotherapy uses exercise and massage to restore movement of muscles and joints. It does not kill cancer cells.
(D) Radiation therapy — Correct. Tumour cells are given a lethal dose of radiation, while the normal tissue around them is protected.
(E) Immunotherapy — Correct. Tumour cells can escape the immune system. The patient is given biological response modifiers such as α-interferon, which activate the immune system to destroy the tumour.
