How is brain cancer diagnosed clinically

Clinical diagnosis of malignant brain tumors is not only to confirm the characteristics of the tumor, but also to observe the tumor's growth site, metastasis, and the degree of damage to the patient's body, etc. Therefore, brain cancer patients must undergo detailed examinations in all aspects. How is brain cancer diagnosed clinically?

Although there are no specific clinical symptoms that can directly determine the occurrence of malignant brain tumors, local neurological symptoms such as the generation and aggravation of intracranial pressure must be paid close attention to. Patients with no history of epilepsy who have sudden epileptic seizures may be caused by bleeding in the tumor, cerebral edema, or cerebrospinal fluid obstruction, and vigilance should also be increased.
Imaging diagnosis is very important in the interpretation of malignant brain tumors.
Imaging examination: In addition to clinical symptoms, with the advancement of science, imaging examinations can quickly and accurately diagnose malignant brain tumors, and are also very helpful for postoperative follow-up treatment. Currently, imaging examinations include:
(1) Computed tomography (CT)
(2) Magnetic resonance imaging (MRI)
(3) EEG and cerebrovascular imaging.
Biopsy: Although advances in imaging examinations have enabled physicians to often diagnose brain lesions through imaging examinations, in some cases a biopsy is necessary to confirm the pathological diagnosis, especially when a brain tumor is assessed to be inoperable. Biopsy surgery can help with subsequent treatment. Currently, biopsy examinations include stereotactic biopsy and craniotomy biopsy.
