Brain cancer is a formidable adversary, affecting thousands of lives worldwide. Understanding the causes and risk factors behind this devastating disease is crucial in its prevention and early detection. While the exact cause of brain cancer remains elusive, several factors can increase a person's susceptibility to this condition. In this blog, we will delve into the potential causes and risk factors associated with brain cancer, shedding light on the complex interplay of genetics, environment, and lifestyle.
How is brain cancer caused?
Brain cancer is multifaceted, and its causes are not always clear-cut. However, research and medical observations have identified several things that may contribute to an increased risk of developing brain cancer. Here, we'll explore these causes of brain cancer in detail:
One of the most notable risk factors for brain cancer is age. Brain tumours are more commonly diagnosed in both children and older adults. However, it's important to note that people of any age can develop brain cancer.
While men are generally more likely to develop brain tumours, specific types of brain tumours, such as meningioma, are more common in women.
Some studies suggest a potential link between exposure to certain chemicals like solvents, pesticides, oil products, rubber, or vinyl chloride and an increased risk of brain cancer. However, scientific evidence supporting this connection is still inconclusive.
Approximately 5% of brain tumours may be associated with hereditary genetic factors or conditions. It includes li-fraumeni syndrome, neurofibromatosis, tuberous sclerosis, turcot syndrome, and von hippel-lindau disease. Moreover, some families show clusters of brain tumours without an apparent hereditary link, which remains under investigation.

Exposure to infections, viruses, and allergens
Infection with the epstein-barr virus (EBV), known for causing mononucleosis, has been linked to an increased risk of central nervous system (CNS) lymphoma. Other viruses and allergens are being studied for their potential associations with brain tumours, with some evidence suggesting that a history of allergies or skin conditions may reduce the risk of glioma.
The role of electromagnetic fields in brain cancer risk, such as those emitted by power lines or cell phone use, remains debatable. Most studies in adults have not found a significant link, but the world health organization (WHO) recommends precautions like limiting cell phone use and using hands-free headsets.
There are notable variations in brain tumour incidence among different racial and ethnic groups. For example, in the United States, white individuals are more likely to develop gliomas. In comparison, black individuals are more susceptible to meningiomas. Moreover, people from northern Europe have a higher incidence of brain tumours than those in Japan.
Exposure to ionising radiation, including previous treatments involving X-rays of the brain or head, has been identified as a risk factor for brain tumours.
Serious head trauma has been studied for its potential link to brain tumours, particularly meningiomas. Additionally, a history of seizures is associated with brain tumours, although the causality remains uncertain, as brain tumours can also cause seizures.
Some studies have suggested that dietary N-nitroso compounds, formed in the body from nitrites or nitrates found in certain foods like cured meats, cigarette smoke, and cosmetics, might increase the risk of brain tumours. However, further research is needed to establish a definitive link.
Conclusion
Brain cancer is a complex disease influenced by various factors, including genetics, environmental exposures, and lifestyle choices. While we cannot always pinpoint the exact cause of an individual's brain cancer, understanding the risk factors associated with this condition is crucial. By recognising these risk factors, individuals and healthcare professionals can work together to develop strategies for prevention, early detection, and improved treatment outcomes. As ongoing research unravels the mysteries of brain cancer, we can hope for more effective measures to combat this formidable foe and enhance the quality of life for those affected by it. Having a comprehensive health insurance plan can provide financial support for advanced diagnostic tests, treatments, and ongoing care, ensuring timely access to the best available resources for managing brain cancer.
