Thermal ablation

Thermal ablation is a medical procedure that involves the use of heat to destroy or damage tissue. It is often used in the treatment of cancer, particularly in cases where surgery is not an option. The heat used in thermal ablation can be generated in several ways, including through the use of radiofrequency, microwave, laser, and ultrasound energy.

Procedure

The procedure for thermal ablation typically involves the insertion of a thin, needle-like probe into the tissue to be treated. This probe is then heated, either by passing an electric current through it (in the case of radiofrequency ablation) or by focusing a beam of energy on it (in the case of laser or ultrasound ablation). The heat generated by the probe destroys the surrounding tissue, causing it to shrink and eventually disappear.

Uses

Thermal ablation is most commonly used in the treatment of cancer, particularly liver cancer, lung cancer, and kidney cancer. It can also be used to treat benign prostatic hyperplasia, a condition in which the prostate gland becomes enlarged.

Risks and complications

As with any medical procedure, thermal ablation carries some risks. These can include infection, bleeding, and damage to surrounding tissues. In rare cases, the heat generated by the procedure can cause burns to the skin or other tissues.
