Brain tumors can be cancerous or benign and can develop due to various risk factors such as age, gender, race, exposure to environmental substances and toxins, lifestyle choices, and genetics. Work environment, genetic diseases, and lifestyle factors like smoking and head injury can also cause brain tumors.
A brain tumor is an abnormal growth of cells that become a solid mass, develop within the skull or central spinal canal, and can be cancerous or benign. Although the causes of brain tumors are unclear, many risk factors may be responsible for this medical problem. Age, gender and race are thought to play a role in the development of brain tumors, as are exposure to certain environmental substances and toxins, lifestyle choices and habits.
Some of the primary causes of brain tumors are unavoidable. For example, men are more likely to develop certain types of brain tumors than women. In general, Caucasians are more likely to develop these abnormal growths than other races. Age can also be a risk factor, as most brain tumors are found in people younger than eight and those older than 70. Despite these factors, brain tumors can occur in people of any age. social class, although less frequently.
The environment is another of the most common causes of brain tumors. The work environment is an example of this. For example, those who work with plastics may be exposed to vinyl chloride, while people who work in the nuclear industry are sometimes exposed to excess radiation. Pathologists and embalmers are often exposed to formaldehyde, and textile workers often come into contact with acrylonitrile, an important ingredient in acrylic fabrics. In very small doses, most of these substances are not considered harmful; however, long-term exposure to any of these chemicals can result in the development of brain tumors.
Though less common, several genetic causes can also cause brain tumors. In some rare cases, these growths may be the result of a family history of brain tumors. Most gene-related cases, however, are caused by inheritance of some genetic disease. Those who inherit neurofibromatosis, for example, are considered to be at higher risk of developing these cancers. Other conditions thought to increase the risk of brain tumors include Turcot syndrome and tuberous sclerosis.
While there is disagreement, some believe that some causes of brain tumors may be related to lifestyle, medical history, or accidents. For example, cigarette smokers are thought to be at a higher risk of developing these growths. Those who have HIV and those who have suffered a head injury are also thought to be at risk.
