Causes of brain cancer 2
The secondary brain tumor occurs when cancer starts from another part of your body and starts to spread in your brain. Some may occur when the person has a history of cancer when a brain tumor is discovered.
Brain cancer can occur at any age between 3-12 and 40-70 years old. Ever since researchers have acquired this data, they have discovered some risk factors. Workers in industries such as rubber and plastic manufacturing, drug manufacturing and oil refining are in much greater risk than those working in other industries. They are also still studying if brain cancer is hereditary since some occur in the members of the same family.
