Brachytherapy refers to?

Correct option is B

Sol. Brachytherapy is a form of internal radiation therapy in which a radioactive source is placed inside or near the tumor site. It delivers high doses of radiation to a localized area, minimizing damage to surrounding healthy tissues. It’s commonly used for cancers like cervical, prostate, and breast.
Explanation of each option:
· (a) Giving anti-cancerous drugs through IV – This refers to chemotherapy, not brachytherapy. Chemotherapy uses systemic drug administration, not radiation.
· (b) Placing radioactive material inside the body – Correct. This is the hallmark of brachytherapy, which allows direct tumor irradiation.
· (c) Passing radioactive rays in the body – Describes external beam radiation therapy, where rays are directed from outside the body.
· (d) None of these – Incorrect, because option (b) clearly defines brachytherapy.
