A brain tumor is an abnormal growth of cells within the brain or its surrounding structures. Tumors can be benign (non-cancerous) or malignant (cancerous). Both types can disrupt normal brain function by pressing on nearby tissues and nerves.
A brain tumor occurs when abnormal cells multiply uncontrollably inside the brain. Tumors may originate in the brain (primary brain tumors) or spread from other body parts (secondary or metastatic brain tumors). Their severity depends on size, growth rate, and location.
Gliomas: Form in glial cells, includes astrocytomas, glioblastomas, and oligodendrogliomas.
Meningiomas: Develop in the protective membranes covering the brain.
Pituitary tumors: Affect the pituitary gland and hormone production.
Medulloblastomas: Common in children, often begin in the cerebellum.
Metastatic tumors: Spread from cancers in other parts of the body.
Genetic mutations
Family history of brain tumors
Radiation exposure
Weakened immune system
Age, with some tumors more common in children and older adults
Persistent headaches, especially worse in the morning
Seizures
Vision or hearing problems
Nausea and vomiting
Difficulty with balance and coordination
Memory loss and personality changes
Weakness or numbness in limbs
Speech and concentration problems
Neurological exam: Tests reflexes, balance, and coordination.
MRI or CT scans: Detailed imaging to locate and measure tumors.
Biopsy: Collecting tissue for laboratory analysis.
PET scans: Checking for cancer activity.
Radiation therapy: High-energy beams destroy abnormal cells.
Chemotherapy: Medications kill or slow cancer cell growth.
Targeted therapy: Focuses on specific tumor-related genes or proteins.
Immunotherapy: Boosts the immune system to fight cancer cells.
Craniotomy: Surgical removal of the tumor through the skull.
Minimally invasive surgery: Uses advanced tools to reduce recovery time.
Shunt placement: Relieves pressure caused by fluid buildup.
Recovery depends on tumor type, stage, and treatment success. Rehabilitation therapies, such as physical, speech, and occupational therapy, help patients regain lost functions. Supportive care, counseling, and lifestyle adjustments improve quality of life.
While brain tumors cannot always be prevented, reducing radiation exposure, maintaining a healthy lifestyle, and regular health checkups may lower risks.
Early detection and treatment improve survival rates and long-term outcomes.
