Causes of Brain Tumors
Researchers have not yet identified a single definitive cause for most types of brain tumors. Similar to other cancer forms, brain tumors arise from genetic changes in the cells within the brain. These changes may affect oncogenes, which are genes that promote cell division, and tumor suppressor genes, which are responsible for inhibiting excessive cell growth. It is important to note that genetic mutations can occur after birth due to exposure to various external factors. Additionally, genetic disorders that increase the risk of developing brain tumors may be inherited from one or both parents.
Risk Factors for Brain Tumors
There are numerous risk factors that may elevate the likelihood of developing a brain tumor. However, it is crucial to understand that the presence of one or more of these factors does not guarantee the development of a brain tumor. Some of these risk factors include:
- A family history of brain tumors.
- Exposure to certain chemical substances.
- Exposure to specific types of radiation.
- Being of Caucasian descent.
- Age, as individuals over 70 years of age and children under eight are more vulnerable to brain tumors.
Symptoms of Brain Tumors
The symptoms associated with brain tumors can vary greatly depending on various factors, such as the tumor’s size and its location. Symptoms often arise from the tumor exerting pressure on neighboring brain areas and causing damage to healthy tissues. It’s essential to recognize that the symptoms may also be indicative of other health issues; therefore, consulting a healthcare professional is advisable if any symptoms appear that may suggest a brain tumor. Notable symptoms include:
- Vision disturbances.
- Memory issues.
- Nausea and vomiting.
- Difficulty concentrating and solving problems.
- Loss of consciousness.
- Dysarthria (speech difficulties).
- Weakness in one part of the body.
- Mood swings.
- Seizures.
