What new cancer treatment is mentioned as supplementing radiation therapy?

• A. Immunotherapy
• B. Chemotherapy
• C. Gene Therapy
• D. Hormone Therapy

Answer: (B)

Combining treatments to intensify the effect of radiation is the principle being tested. Chemotherapy can act as a radiosensitizer, meaning certain drugs make cancer cells more vulnerable to the DNA-damaging effects of radiation. When used together, radiation and chemotherapy can kill more cancer cells than either would alone, and they can also address cancer cells that have spread beyond the primary tumor. This combination is commonly described as chemoradiation, reflecting how the two therapies work in tandem. The other options play different roles: immunotherapy boosts the body's immune response against cancer, gene therapy aims to modify genetic material within cells, and hormone therapy blocks hormones that some cancers need to grow. In the context of supplementing radiation therapy, chemotherapy is the classic partner, hence the best choice.
