Infection with the Epstein-Barr virus (EBV) increases the risk of CNS lymphoma. EBV is more commonly known as the virus that causes mononucleosis or “mono.” In other research, high levels of a common virus called cytomegalovirus (CMV) have been found in brain tumor tissue.

Is brain cancer primary or secondary?

Primary brain tumors start in the brain and tend to stay there. Secondary brain tumors are more common. These cancers start somewhere else in your body and travel to the brain. Lung, breast, kidney, colon, and skin cancers are among the most common cancers that spread to your brain.

How are primary brain tumors classified?

Primary tumors are categorized as glial (composed of glial cells) or non-glial (developed on or in the structures of the brain, including nerves, blood vessels and glands) and benign or malignant.

What is the most common form of brain cancer?

In fact, meningioma is the most common brain tumor, accounting for about 30 percent of them. Meningioma tumors are often benign: You may not even need surgery.

Can HPV cause brain cancer?

Just because the human papilloma virus (HPV) is a sexually transmitted disease doesn’t mean that’s the only way you can get it. HPV is known to cause many cancers, including cancer of the head and neck.

Are HPV and EBV related?

Co-infection of EBV and HPV is frequently found in endemic NPC, but it is less common in Caucasians than in Asian populations; HPV is an important etiologic factor in EBV-positive NPC among Caucasians [15]. Furthermore, co-infection of HPV and EBV may also cooperatively affect neoplastic transformation [53].

What virus causes glioblastoma?

Glioblastoma multiforme (GBM) is a grade IV glioma associated with a poor outcome despite recent advances in chemotherapy. The etiology of gliomas is unknown, but neurotropic viruses including the Epstein-Barr virus (EBV) that is transmitted via salivary and genital fluids have been implicated recently.

Are brain tumors contagious?

Doctors cannot explain why one person gets a brain tumor and another doesn’t, but they do know that no one can “catch” a brain tumor from another person. Brain tumors are not contagious. Although brain tumors can occur at any age, studies show that they are most common in two age groups.
