What is Diagnosis and Treatment of Brain Tumors (Gliomas, Meningiomas)?

Brain tumors can be benign (non-cancerous) or malignant (cancerous). Two common types of brain tumors are gliomas and meningiomas:

  • Gliomas: These tumors arise from glial cells, which support nerve cells in the brain. Gliomas can be low-grade (slow-growing) or high-grade (fast-growing and more aggressive).
  • Meningiomas: These tumors develop from the meninges, the protective membranes covering the brain and spinal cord. Meningiomas are typically benign but can cause significant symptoms depending on their size and location.
How to diagnose Diagnosis Brain Tumors (Gliomas, Meningiomas)? When to consult a doctor for Brain tumors surgery?

Brain tumors are diagnosed through imaging tests such as MRI (Magnetic Resonance Imaging) or CT (Computed Tomography) scans, followed by a biopsy to confirm the tumor type.

You should consult a doctor if:

  • Persistent, worsening headaches that don’t improve with over-the-counter medications.
  • Seizures with no history of epilepsy.
  • Neurological symptoms, such as unexplained weakness, vision or speech difficulties, or confusion.
  • Behavioral or cognitive changes that interfere with daily activities.
  • Nausea and vomiting associated with neurological symptoms.

Causes
  • Inherited conditions like neurofibromatosis or Li-Fraumeni syndrome may increase the risk of gliomas and meningiomas.
  • Previous exposure to radiation, especially to the head, can increase the risk of brain tumors.
  • Gliomas are more common in middle-aged adults, while meningiomas tend to occur more frequently in older adults, especially women.
  • Prolonged exposure to certain chemicals or toxins may increase risk, though more research is needed.
Symptoms
  • Headaches
  • Seizures
  • Nausea and Vomiting
  • Cognitive Changes
  • Weakness or Numbness
  • Vision Problems
  • Hearing Loss or Tinnitus
Frequently Asked Questions

Recovery depends on the tumor’s size and location, and the extent of surgery. Patients may need rehabilitation for physical, occupational, or speech therapy if neurological functions are affected.

Yes, radiation therapy is commonly used for brain tumors, especially when complete surgical removal isn't possible. Techniques like stereotactic radiosurgery allow precise targeting of tumor cells, minimizing damage to surrounding healthy tissue.

Patients may need to avoid activities that increase intracranial pressure, manage stress, follow a balanced diet, and consult their doctor regularly. Support from family, friends, and support groups can also aid recovery.
