The technique for thermal ablation in the lung by using radiofrequency ablation was first described in 1995 for use in animal lung tumor models and then in 2000 in humans. [1-2] Microwave ablation has emerged as a newer ablation modality and an addition to the arsenal of minimally invasive cancer care.

The newer ablation modalities, such as IRE, microwave ablation (MWA), and high-intensity focused ultrasound, may help overcome the challenges in tumor size. [ 92 ] The first human studies have proven the safety of IRE for the ablation of renal masses; however, the effectiveness of IRE through histopathological examination of an ablated renal ...

Transurethral needle ablation (TUNA) operates with a different type of energy, radio frequency (RF) energy, but is designed along the same premise as TUMT devices, that the heat the device generates will cause necrosis of the prostatic tissue and shrink the prostate. The TUNA device is inserted into the urethra using a rigid scope much like a ...
The treatment involves inserting a special microwave urinary catheter into the hyperplastic prostatic urethra. The microwave antenna within the catheter then emits microwaves to heat and destroy the surrounding prostatic tissue. [citation needed] The procedure can take from 30 minutes to one hour and is well tolerated by patients.

Cryoablation has been explored as an alternative to radiofrequency ablation in the treatment of moderate to severe pain in people with metastatic bone disease.The area of tissue destruction created by this technique can be monitored more effectively by CT than RFA, a potential advantage when treating tumors adjacent to critical structures.
