of Brain Tumors
1. Primary Brain Tumors
o
Originates in the brain. Examples include gliomas and
meningiomas.
2. Secondary (Metastatic) Brain Tumors
o
Originate in other parts of the body and spread to the
brain.
3. Gliomas
o
Arises from glial cells. Types:
§ Astrocytomas
§ Oligodendrogliomas
§ Ependymomas
4. Meningiomas
o
Tumors that develop in the meninges (brain and spinal
cord membranes).
5. Pituitary Tumors
o
Affect the pituitary gland, influencing hormonal
activity.
6. Schwannomas
o
Typically benign tumors that arise from Schwann cells,
e.g., vestibular schwannomas.
7. Medulloblastomas
o
Common in children, arising from the cerebellum.
8. Craniopharyngiomas
o
Benign tumors near the pituitary gland, affecting
growth and hormone regulation.
9. Pineal Region Tumors
o
Tumors located in or around the pineal gland.
10. CNS Lymphomas
11.
Choroid Plexus Tumors
12.
Hemangioblastomas
What is Brain Tumors?
A brain
tumor is an abnormal growth of cells within or around
the brain. These growths can be classified into two main types:
1. Benign Brain Tumors: These are
non-cancerous growths that typically grow slowly and are less likely to invade
surrounding brain tissues. Despite being non-cancerous, they can still cause
significant health issues due to their location and pressure on surrounding
brain structures.
2. Malignant Brain Tumors:
These are cancerous growths that tend to grow more quickly and may invade or
spread to surrounding brain tissues. Malignant brain tumors can originate in
the brain (primary brain tumors) or spread to the brain from other parts of the
body (secondary or metastatic brain tumors).
Symptoms of brain tumors vary depending on their size,
location, and rate of growth. Common symptoms include headaches, seizures,
changes in vision or hearing, difficulty with balance or coordination,
cognitive or memory issues, and personality changes. Diagnosis typically
involves imaging tests like MRI or CT scans, and treatment options may include
surgery, radiation therapy, chemotherapy, or targeted therapies.
