Question

What is the treatment method that involves placing radioactive seeds directly in a tumor?

1) Radiation therapy
2) Chemotherapy
3) Surgery
4) Immunotherapy

Answer 1

The treatment method that involves placing radioactive seeds directly in a tumor is called brachytherapy, which is a type of radiation therapy. In brachytherapy, small radioactive seeds or sources are implanted near or inside the tumor to deliver targeted radiation and destroy cancer cells. So the correct answer is 1) Radiation therapy.

Answer 2

The treatment method where radioactive seeds are placed directly in a tumor is brachytherapy, a form of radiation therapy. It uses isotopes like iodine-135 or palladium-103 to deliver targeted radiation to the cancerous area.

Step-by-step explanation:

The treatment method that involves placing radioactive seeds directly in a tumor is known as brachytherapy, which is a type of radiation therapy. This procedure involves placing ionizing pellets (seeds) or rods directly at the site of the tumor, using isotopes like iodine-135 or palladium-103 which emit radiation to kill cancer cells or prevent them from dividing. It is often used for cancers that are localized, such as prostate cancer, and can be delivered through surgically implanted pellets or temporarily inserted rods.
