Multiple occupying lesions in bilateral large and small cerebral hemispheres are considered as metastatic tumors, and the specific treatment options mainly include surgical treatment, radiotherapy, chemotherapy, targeted therapy, and treatment for the primary tumor. 1. Surgery: for multiple metastatic tumors, some of the lesions are large in size and oppress the surrounding tissues, so they can be treated by surgery, which mainly relieves the symptoms. 2. Radiotherapy: Radiotherapy can be chosen for brain metastases. 3. Chemotherapy: if there are multiple metastases, you can follow the doctor’s instruction to apply chemotherapy drugs regularly, and the commonly used drugs are cisplatin and so on. 4. Targeted therapy: some primary tumors are accompanied by gene mutation, so they can be treated with targeted drugs as prescribed by doctors, such as sorafenib and so on. 5. Primary tumor treatment: it is necessary to carry out relevant treatment for the primary tumor to prevent continuous aggravation of the condition, which is usually controlled by surgery, radiotherapy and chemotherapy. If multiple brain metastases are found, it is necessary to seek medical treatment in time and be admitted to hospital for treatment, and carry out standardized treatment under the guidance of clinicians, so as to avoid delaying the condition and causing serious consequences.
