Lung cancer particle implantation is mainly one of the means to treat lung cancer. The particles are implanted into the cancerous lesions in the lungs, and the radioactive substances on the particles kill the cancer cells, thus serving the purpose of treating lung cancer. It is also known as a radioactive therapy in the lung tissue. Most of the lung cancer patients have certain clinical efficacy. After implantation, the particles will interfere with the proliferation of lung cancer cells and cause the lung cancer cells to reach apoptosis. With the implantation of the particles, a low dose of radiation will be released, which can kill the localized lung cancer cells and will not have too much effect on the surrounding healthy lung tissues. This is a good treatment for most lung cancer patients.
