What is cryoablation technology? Can cryoablation really cure cancer?

Cryoablation is an important ablation technique. Its principle is that when the high-pressure argon gas expands rapidly, it absorbs the heat around it, so that the temperature of the surrounding tissues drops rapidly, leading to the formation of ice crystals inside and outside tumor cells, cell rupture, intimal injury, tumor venules and arterioles thrombosis, and tumor cells die due to ischemia and hypoxia. I can't. Cryoablation is a radical treatment and palliative treatment. The biggest advantage of cryoablation is minimally invasive, which can cure local tumors, such as early lung cancer and liver cancer, or relieve patients' symptoms.
