Can ordinary brain CT scan detect brain cancer?

Intracranial malignant tumors mainly include gliomas, malignant meningiomas, germ cell tumors, and metastatic tumors, which can be diagnosed mainly through head CT. A few early and relatively small tumors are easy to be missed. Brain tumor examination MRI should be more accurate. CT brain malignant tumors can usually be preliminarily diagnosed, because in clinical practice, we also make a preliminary diagnosis based on imaging examinations and the patient's clinical symptoms, but brain malignant tumors ultimately need to be diagnosed based on surgical pathology or puncture biopsy to determine whether the intracranial tumor, including benign tumors, is a malignant tumor.

Symptoms of Brain Cancer

Intracranial tumors include benign tumors and malignant tumors. Malignant tumors include gliomas, malignant meningiomas, germ cell tumors, and intracranial metastases. Early tumors are relatively small and generally have no obvious symptoms. As the tumor gradually increases, it can cause headaches, dizziness, nausea, vomiting, impaired consciousness, hemiplegia, aphasia, convulsions, epileptic seizures, and even coma. Brain metastasis cancer, because only metastatic lesions can be called cancer, primary brain lesions are usually not called cancer, such as primary brain tumors, and even malignant gliomas are also considered brain tumors, brain germ cell tumors, pituitary tumors, brain acoustic neuroma, and brain tumors are considered brain tumors. Tumors and cancers are both very malignant physical diseases, especially most cancers cannot be treated in the late stages.

Is early stage brain cancer serious?

The diagnosis of brain malignant tumors is usually a very serious disease. The continued growth of intracranial tumors will compress the surrounding normal brain tissue, causing local edema and increased intracranial pressure, leading to headaches, vomiting, limb movement disorders, drowsiness, coma and even death. Intracranial tumors include benign tumors and malignant tumors. Early brain cancer mainly refers to benign and malignant tumors, including meningiomas and low-grade gliomas. Brain cancer mostly refers to intracranial gliomas.
