Headaches are a frequent complaint, but a new or worsening headache, especially one that wakes a person up in the morning, can signal a serious underlying issue. Medical professionals advise that if a headache pattern changes or is accompanied by vomiting, a doctor should evaluate the patient for a brain tumor. Brain tumors present with varied symptoms depending on their location. Headaches are the most common symptom, and increased pressure inside the skull often leads to nausea and vomiting. Tumors affecting the motor cortex may cause weakness in the arms or legs or difficulty walking. Lesions near language centers can result in slurred speech or impaired comprehension. Pressure on the optic nerve might produce narrowed visual fields or double vision.
Diagnosis and Treatment
Doctors typically use magnetic resonance imaging (MRI) to assess the tumor’s location, size, and its relationship to surrounding nerves and blood vessels. While computed tomography (CT) scans are useful in emergencies to detect bleeding or major lesions, MRI provides the detailed images needed for a full evaluation. Additional tests such as PET-CT, cerebral angiography, functional MRI, and biopsy may follow depending on the findings.
Treatment options depend on the tumor’s type, location, size, growth rate, and the patient’s age and health. The primary approach is surgical removal, which helps relieve pressure and provides a sample for pathology. New techniques like precision navigation surgery, microscopic surgery, endoscopic-assisted procedures, intraoperative neuro-monitoring, and awake brain surgery have reduced damage to healthy tissue. For small or deep-seated tumors, radiosurgery offers a non-invasive alternative. This procedure uses equipment like the Gamma Knife, CyberKnife, or linear accelerator-based systems to deliver a high dose of radiation directly to the tumor.
Why Early Detection Matters
Radiosurgery is a key option for residual or recurrent tumors, as well as for meningiomas, vestibular schwannomas, pituitary adenomas, and brain metastases. It may be used alone or after surgery. However, if a tumor is large, causes significant swelling, or requires a tissue diagnosis, surgery remains the priority.
While brain tumors are not easily preventable, early detection significantly improves the chances of a positive outcome. Patients with a history of cancer should also consider the possibility of metastatic brain tumors. Professor Cho Sung-jin of the Department of Neurosurgery at Soon Chun Hyang University Hospital Seoul noted that depending on the tumor type and timing of detection, these conditions can be sufficiently treatable. With recent advances in microsurgery, navigation-guided surgery, awake procedures, and precision radiosurgery, doctors can now provide safer and more effective personalized treatments. If persistent and new neurological symptoms appear, they should not be dismissed as simple fatigue or stress.
