Interventional lung cancer particle surgery is a locally controlled endoradiotherapy treatment that is only suitable for certain specific groups of lung cancer patients. To briefly introduce, the treatment process is that after percutaneous puncture, radioactive particles are pierced into the tumor tissue and arranged according to the previously formulated plan to kill the tumor through the close irradiation of the particles, which is a kind of minimally invasive treatment of internal radiation. Because it is a local treatment and invasive, it is more suitable for local lung tumor tissues close to the pleura, and the treatment is very insensitive when the patient has distant metastasis or chest and abdominal fluid, but the effect is okay if it is for the limited lung lesions close to the pleura. In conclusion, it is a suitable treatment for localized lung cancer and can be used as a method to control tumor progression for inoperable patients, often needing to be combined with other treatments to achieve the best treatment effect
