How Do You Get Brain Cancer?
How to get brain cancer – The brain cancer primary originates in the parenchyma of the brain, the spinal cord or nerves. Some tumors that arise from the coverings of the brain or spinal cord (meninges) are also considered primary brain tumors. Metastatic brain tumors have spread from cancer located in other parts of the body, most commonly lung, breast, and colon. The overall risk during the life of having a brain tumor is less than 1%. There are many different types of brain tumors, according to the cells that are affected and its appearance under a microscope. Tumors can be classified into four general categories:
How to Get Brain Cancer: Gliomas
How to get brain cancer – These tumors are formed from glial cells, which help to sustain and protect critical areas of the brain. Gliomas represent the most frequent type of brain tumor in adults so that they are responsible for approximately 42% of brain tumors in them. Gliomas are subclasifican in function of cell types that are affected:
Astrocytoma: star-shaped cells that protect neurons. Tumors of these cells can spread from the primary focus to other areas of the brain but rarely spread outside the central nervous system. Astrocytomas are graded from I to IV depending on the speed of progression:
- Grade I (pilocytic astrocytoma): slow growing, with little tendency to infiltrate surrounding brain tissue. More frequent in children and adolescents.
- Grade II (astrocytoma diffuse): growth very slow, with some tendency to infiltrate surrounding brain tissue. Observed mostly in young adults.
- Grade III (anaplastic astrocytoma/malignant): these tumors grow rather quickly and infiltrate surrounding brain tissue.
- Grade IV (glioblastoma multiforme, GBM): a very aggressive and deadly brain cancer. Unfortunately, this is the most common form of brain tumor in adults, accounting for 67% of all astrocytomas.

Oligodendroglioma: these cells produce myelin, a fatty substance that forms a protective sheath around the nerve cells. How to get brain cancer – Oligodendrogliomas, which make up the 4% of brain tumors, mostly affect people over 45 years old. Some subtypes of this tumor are particularly sensitive to treatment with radio-and chemotherapy. Half of the patients with oligodendrogliomas are still alive after five years.
- Frequent headaches (reported by 50% of patients)
- Blurred vision
- Nausea, vomiting, or both
- Personality changes or cognitive
How do you get brain cancer – Other symptoms of cancer and brain tumors are specific to your location, such as seizures, altered speech, weakness or numbness on one side and problems with coordination, balance, and mobility.
