The cause of primary brain tumors is unknown, but people who work with rubber and certain chemicals have a greater-than-average risk of developing them
The most common primary brain tumors include gliomas such as astrocytomas, ependymomas, and oligodendrogliomas
Gliomas are the most prevalent primary brain tumors
Tumors that initially arise and grow within the brain are termed primary tumors
Most adult brain cancers are not primary tumors, but are the result of primary cancer that has spread from other areas of the body

Primary brain tumors can be benign or cancer.Usually, benign tumors are often removed, and that they seldom grow back.Benign brain tumors usually have a clear border or edge. Cells from benign growths rarely invade tissues around them.They don't spread to other parts of the body.Benign tumors can continue sensitive areas of the brain and cause serious health problems.Unlike benign tumors are sometimes life-threatening.Benign brain tumors may become turn into cancer.Malignant brain tumors contain cancer cells:Malignant brain tumors are generally more serious and sometimes are a threat to life.They are likely to grow rapidly or invade nearby healthy brain tissue.Cancer cells may break free from the malignant brain cancer and spread to other parts of the brain or to the medulla spinal.
Each year, approximately 700,000 people in the United States are living with a primary brain tumor. It is estimated that around 80,000 new cases of primary brain tumors are diagnosed in adults every year. Brain tumors can occur at any age, but they are most common in older adults and children.
