What method does cryosurgery utilize to destroy cancer tissue?

Cryosurgery utilizes extremely cold temperatures to destroy cancerous tissue. This method involves the application of cryogens, such as liquid nitrogen or argon gas, which can substantially lower the temperature of the targeted tissue. The freezing process causes ice crystals to form within the cells, leading to cell damage and subsequent tissue death. This technique is often used for certain types of tumors, particularly those found on the skin or in accessible areas, as well as in some internal procedures.

The effectiveness of cryosurgery is due to its ability to selectively freeze and kill malignant cells while minimizing damage to the surrounding healthy tissue. By employing cold temperatures, cryosurgery capitalizes on the biological response of cells to extreme cold, making it a valuable treatment option in the arsenal of cancer therapies.
