Infiltrative lung cancer, also known as invasive lung cancer, cannot be operated with low lung function, and it is possible to be treated with targeted therapy, which can only be known after genetic testing. Targeted therapy is the use of targeted drugs to carry out targeted treatment on the tumor that has been clearly defined, which can make the drugs act directly on the tumor cells. Generally speaking, before carrying out the targeted drug treatment, it is necessary to do genetic test for the patients first, and the targeted drug will be effective only when the genetic mutation is found. Therefore, it depends on the result of genetic test whether or not targeted therapy can be done for infiltrative lung cancer. Invasive lung cancer means that the cancer cells have broken through the epithelial basement membrane. Once the cancer cells break through the basement membrane, there is a possibility that the cancer cells may directly invade the surrounding tissues and organs, or cause aggravation of the disease through lymphatic metastasis or blood line metastasis, in which case, the aim of the treatment is mainly to slow down the progression of the disease and to achieve clinical cure as far as possible. In addition to surgery and targeted therapy, there are other treatments for invasive lung cancer, such as chemotherapy, radiotherapy, interventional therapy and immunotherapy, etc. It is suggested that patients with invasive lung cancer should choose appropriate treatments under the guidance of doctors.
