Pituitary adenomas are tumors that occur in the pituitary gland.
Non-invasive and non-secreting pituitary adenomas are considered to be benign in the literal as well as the clinical sense; however a recent meta-analysis (Fernández-Balsells, et al. 2011) of available research has shown there are to date scant studies – of poor quality – to either support or refute this assumption.
A brain tumor occurs when abnormal cells form within the brain.
There are two main types of tumors: malignant tumors and benign (non-cancerous) tumors.
