Yes, use the radiographic knife, which is currently the most advanced stereotactic radiotherapy. The treatment of lung cancer brain metastases is painless and non-invasive, with good effects and small side effects, and it is not necessary to implant a stent in the head of the patient during treatment. The Cyberknife is the world''s newest full-body stereotactic radiosurgery treatment device. It only needs 1 to 5 times of irradiation to kill tumor tissue. It is the only comprehensive "no wound, no pain, no bleeding, no anesthesia, and recovery period. Short" and other advantages of whole body radiation surgery.

        Furthermore, the advantages of the jet knife in the treatment of metastatic small cell lung cancer are very unique. Because the beam knife can treat multiple tumors at the same time, it can also treat metastatic lesions at the same time as the primary tumor. In addition, the treatment of brain metastases without the need for stent implantation reduces the inconvenience and pain for patients.

        The best treatment for brain metastasis is local radiotherapy, but if there is no metastasis elsewhere in the body, and the intracranial metastasis is a single lesion, it can be opened Craniotomy, combined with chemotherapy and radiotherapy, systemic medication for brain metastasis also depends on cell type, but depends on whether the drug can penetrate the blood-brain barrier, such as dichloroethyl nitrosourea, cyclohexyl nitrosourea, etc. Fat-soluble drugs can penetrate the blood-brain barrier and have a therapeutic effect on brain metastasis, but you should refer to the doctor''s recommendations for specifics. At the same time, you must maintain a good attitude and be optimistic. This psychology is very important.

        In general, the body of patients with gastric cancer is already very weak, and chemotherapy itself is also very harmful to the body, so it is best to choose radiotherapy.
