Introduction
Brain cancer develops when abnormal brain cells grow uncontrollably and form a tumor. These tumors may appear benign (non-cancerous) or malignant (cancerous). However, malignant brain tumors grow aggressively and can quickly become life-threatening if treatment does not begin on time.
Global Statistics
Worldwide, doctors diagnose over 300,000 new brain tumor cases every year. Although brain cancer accounts for only about 2% of all cancers, its impact remains serious due to complications.
Moreover, medulloblastoma appears most frequently in children. In adults, glioma and meningioma occur more often. Studies also show that men face a slightly higher risk than women.
⚠️ Statistics may vary depending on country and reporting year.
Causes
Researchers have not yet identified a single definite cause. However, several risk factors may increase the chance of developing brain cancer:
High exposure to radiation, especially to the head
Family history and genetic predisposition
Rare genetic disorders such as Neurofibromatosis
Weak immune system
Increasing age
Symptoms
- Symptoms vary depending on the tumor’s size and location. Common warning signs include:
- Persistent or worsening headaches
- Nausea and frequent vomiting
- Blurred or reduced vision
- Seizures without prior history
- Memory loss or personality changes
- Weakness on one side of the body
- Difficulty speaking or understanding language
- Therefore, anyone experiencing long-term neurological symptoms should seek medical attention immediately.
Types of Cancer
Glioma
This tumor originates from glial cells and remains the most common type of brain cancer.
Meningioma
This tumor develops from the meninges, the protective layers of the brain. Most cases remain benign.
Medulloblastoma
Doctors commonly diagnose this tumor in children, and it usually affects the cerebellum.
Pituitary Tumor
This tumor grows in the pituitary gland and often disrupts hormone balance.
Metastatic Brain Tumor
This type spreads to the brain from cancers such as lung, breast, or kidney cancer.
Tests Used to Diagnose
Doctors use several diagnostic tools :
- MRI (Magnetic Resonance Imaging)
- CT Scan
- PET Scan
- Biopsy (tumor tissue analysis)
- Neurological examination
- Blood tests (supportive role only)
Prevention Tips
Although complete prevention remains difficult, certain habits can lower risk:
- Avoid unnecessary radiation exposure
- Use headphones during mobile phone calls
- Follow a balanced and nutritious diet
- Quit smoking and limit alcohol intake
- Schedule regular health check-ups
- Consult a doctor promptly for chronic headaches or seizures
Conclusion
Brain cancer poses a serious health challenge, but early detection and timely treatment can significantly improve outcomes. Awareness plays a vital role in survival and quality of life. Therefore, do not ignore unusual neurological symptoms.
