A large range of interventional treatments for prostate cancer includes two aspects: 1) putting particles during puncture, or performing ablation therapy, in which the effectiveness is also clinically confirmed; 2) performing embolization and chemotherapy with arterial perfusion, which is a cutting-edge aspect of research, but not used as a universal technique in clinical practice. The ethical issues involved in prostate cancer, for those who cannot be operated, can try to use non-operative or less invasive means, these means are collectively called interventional means, including the use of particles, ablation means. The new technology of ablation is called cryogenic technology, the principle of which is to use argon and helium gas at -130°C to -140°C to produce a therapeutic effect, called argon helium knife, the treatment of the prostate gland has the protection of blood vessels, treatment damage is slight, and is relatively mature technology.
