The terms benign and pseudotumor derive from the fact that increased intracranial pressure may be associated with brain tumors. Those patients in whom no tumour was found were therefore diagnosed with pseudotumor cerebri (a disease mimicking a brain tumor).
The American Brain Tumor Association estimates that about 40,900 people will be diagnosed with a primary brain tumor in the US this year (rate of 14 per 100,000 people). Metastatic (secondary) brain tumors are more common than primary brain tumors by at least 10 to 1, and they occur in 20% to 40% of cancer patients.rimary brain tumors may be benign or malignant. A benign brain tumor grows slowly, has distinct boundaries, and rarely spreads. Although its cells are not malignant, this tumor composed of benign cells and located in vital areas can be considered life-threatening.
