Acoustic neuroma, also known as vestibular schwannoma, is a rare, slow growing non-cancerous tumor that grows on the hearing and balance nerves in the brain. They may be accompanied by hearing loss, tinnitus, and slight imbalance.

Gliomas are a type of cancerous brain tumor that grow on the supporting structures of the brain, called the glial cells, and range from slow-growing early-stage tumors to a more developed malignant form called a glioblastoma.

Lymphoma is a less common malignant brain tumor and more commonly seen in the elderly. It will often present suddenly with a loss of neurologic function, confusion, forgetfulness, or a deficit, such as speech problems or weakness. Patients are typically treated with surgical biopsy followed by steroids and other treatments including chemotherapy, radiation, and novel clinical trials.

Meningioma is one of the most common non-cancerous tumors that can occur within the head and brain. Meningioma is a tumor that typically appears on the brain’s outer covering (the meninges) and grows slowly, usually only a millimeter or two per year.

Metastatic brain tumors, also called brain metastases, are the most common type of cancerous brain tumors in adults. These tumors are a result of a cancer that started in another part of the body (for example, lung, breast or colon) and spread to the brain through the bloodstream.

Pituitary tumor (or pituitary adenoma) is most often a benign tumor that develops in the pituitary glands. 30% of these tumors secrete active hormones which may cause infertility, altered body shape or high blood pressure. Other types of tumors don’t secrete hormones, usually affect the elderly and are accompanied by visual loss.
