Tumors occur when cells in the brain grow abnormally. They can be cancerous (malignant) or benign (benign). Some of the factors that can lead to this are:
1. Genetics
A very small percentage of brain tumors are hereditary. If someone in the family has such conditions, it is likely to be passed on to the next generation. People with genetic diseases such as neurofibromatosis are more likely to develop brain tumors.
2. Radiation Exposure
Excessive exposure to ionizing radiation is a major cause of brain tumors. For example, people who have previously received radiation to the head for other treatments are more likely to develop tumors years later.
3. Age
Most brain tumors are found in older people. However, certain types of tumors (such as medulloblastoma) are also common in children.
4. Exposure to chemicals
Some studies suggest that people who work in industrial plants and are regularly exposed to pesticides, rubber, and petroleum products are at higher risk of developing tumors.
5. Weakened immune system
A weakened immune system due to diseases such as HIV/AIDS or medications taken after an organ transplant can lead to brain tumors such as lymphoma.
6. Metastasis (Secondary Brain Tumor)
A secondary brain tumor is when cancer that has originated in another organ (such as the lung, breast, or kidney) spreads to the brain through the bloodstream. Most brain tumors seen today are of this type.
Key symptoms to watch out for:
Persistent and severe headache (especially in the morning).
Sudden onset of seizures.
Blurred or double vision.
Changes in speech or gait.
Memory loss and personality changes.
