The Freezing of a Malignancy with a Liquid Nitrogen Probe

Question

The freezing of a malignancy with a liquid nitrogen probe is:
A) Particle-beam therapy.
B) Cryosurgery.
C) Radiation therapy.
D) Chemotherapy.

Accepted Answer

The freezing of a malignancy with a liquid nitrogen probe is a form of cryosurgery. This technique is used to kill cancer cells by freezing them with a cryoprobe, which is a thin metal rod filled with liquid nitrogen. Once the probe is inserted into the tumor, the extremely low temperature destroys the cancer cells. Particle-beam therapy, radiation therapy, and chemotherapy are all different types of cancer treatment that use different mechanisms to kill cancer cells.
