Whilst there are a few lifestyle factors that can make individuals more prone to certain cancers, such as poor dietary habits, heavy drinking, and smoking, other causes are also present that few people can control. These include one’s genetic makeup and prolonged exposure to hidden environmental pollutants.
Both can also be behind the development of brain tumours, but since the exact cause of brain cancer is not exactly known, several factors have been linked to their development. So, what are they, and can they help individuals to reduce their risk of developing brain tumours?
Genetics plays an important role in cancer and disease development. Having certain health conditions and genetic disorders can also increase the chances of developing brain tumours.
Disorders such as neurofibromatosis, which is categorised by the development of tumours in the spinal cord, nervous system, and brain, are one such example of how genetic factors and disorders can increase an individual’s risk of developing both benign and malignant brain tumours.
Individuals with a general family history of brain tumours may also have a higher risk of developing the condition themselves.
It is well known that prolonged exposure to certain forms of radiation can increase the risk of developing certain cancers. Brain tumours are just one form of cancer that is thought to be caused by radiation exposure.
Since radiation is invisible, it is hard to avoid it in the environment. However, most environmental radiation is usually caused by accidents or leaks from nuclear power stations, so the most likely encounter with radiation in the environment would be through medical tests and treatments such as x-rays and radiation therapy for previous cancers.
Although the contact with radiation is made, one of the side effects is the possible development of brain tumours sometime after the initial exposure. However, the chances of developing cancer through one or two X-rays every few years are thought to be small.
As mentioned, an individual’s lifestyle can have major implications regarding their health and wellness. Those who consume large amounts of junk food and drink too much alcohol put themselves at risk of developing certain diseases, such as brain cancer. In addition to this, if individuals also choose to smoke tobacco regularly, the risk increases further.
Here, individuals can take control and reduce the risk of developing brain tumours and other forms of cancer. Not smoking and drinking in moderation, along with consuming foods that are high in antioxidants, such as fruits, vegetables, and nuts, can all supply the body with the ammunition needed to prevent or fight cancer by boosting the immune system and reducing the number of free radicals in the body.
Exercise can also help boost immunity and health in general. It can prevent obesity as well, which is another cancer risk factor.
When it comes to health and well-being, the immune system is the first line of defence against bacteria, viruses, and other disease-causing agents. However, the immune system is also vulnerable to certain disorders, and various ones can affect its functionality, leading to autoimmunity and other problems.
Those with immune system disorders, such as individuals with HIV or AIDS, often have weakened immune systems that can decrease the body’s ability to fight off abnormal cell growth, including the growth of tumours such as those associated with cancer of the brain.
Individuals with compromised immune systems may be at a higher risk of developing cancers such as brain tumours compared to those with healthy immune function, but this can be said for many other forms of cancer. However, even individuals without disorders of the immune system can still get brain tumours because, apart from the risk factors mentioned, the exact cause of brain tumours remains unknown.
