What exactly is interventional therapy is still unfamiliar to many people, because the large scope of traditional medicine is only internal medicine and surgery, therefore, when it ventured into the forest of medicine more than 30 years ago, it was jokingly called “third party”. Of course, this is a medical naming problem, but more important is the content and effect. One of the most basic reasons why it has been able to gain a foothold, survive and develop is that it meets the needs of social development, adapts to and promotes the development and progress of medical science, especially in the anti-tumor treatment, which gradually forms a comprehensive treatment with interventional therapy as the main treatment and plays an increasingly active and important role. The essence of interventional therapy is minimally invasive. What is minimally invasive? It means less invasive, faster recovery and better effect. How is interventional tumor treatment done? Under the monitoring of imaging system (ultrasound, CT, MR), special equipment is used to guide to the target tumor area and treat it through vascular or non-vascular route, and the patient can carry out normal activities the next day. Interventional tumor treatment is a discipline characterized by technology and has a strong dependence on technical equipment. Argon-helium cryotherapy is one of the new technological methods of antitumor treatment.
