1.What are the early symptoms of brain cancer?
Common symptoms of brain cancer include persistent headaches (especially those worsening in the morning), nausea and vomiting, seizures, limb weakness or numbness, speech difficulties, and vision loss.
2.What is the difference between brain cancer and brain tumors?
Brain tumors can be benign or malignant; "brain cancer" usually refers to malignant tumors.Benign tumors, such as meningiomas, grow slowly and have well-defined boundaries.Malignant tumors, such as gliomas, exhibit infiltrative growth and are prone to recurrence.
3.What are the surgical treatment options for brain cancer?
The surgical goal is the maximal safe resection of the tumor and the relief of intracranial pressure.Intraoperative neuronavigation, fluorescence guidance, and neurophysiological monitoring are used to enhance precision.
4.What is minimally invasive treatment for brain cancer?
Stereotactic biopsy provides a definitive diagnosis with minimal trauma and rapid recovery.Stereotactic radiotherapy (e.g., Gamma Knife) precisely targets small tumors.Neuroendoscopic transnasal surgery is used to remove skull base tumors.
5.How are radiotherapy and chemotherapy combined for brain cancer?
The standard postoperative treatment for high-grade glioma consists of concurrent chemoradiotherapy followed by adjuvant chemotherapy.Radiotherapy and proton therapy are used to precisely target the tumor.Temozolomide is a commonly used chemotherapy drug.
6.How can patients with brain cancer manage seizures?
Patients with brain cancer often experience seizures and require regular anti-epileptic medication for prevention.Avoid triggering factors such as fatigue and flashing lights.During a seizure, take precautions to prevent injury.
7.Follow-up after brain cancer treatment?
Undergo regular post-operative MRI follow-ups to monitor for recurrence (every 3 months for the first 2 years).Watch for new symptoms such as headaches or seizures.Manage cerebral edema and intracranial pressure.Perform functional exercises to improve limb mobility.
