Pituitary tumor are benign. Symptoms develop gradually, because the tumor growth is slow and the tumor usually does not produce hormones itself. This type of tumor is called a 'non functioning tumor'. When the tumor grows it can start compressing other structures, like the optic nerves and/or compress the normal pituitary gland. This together can cause the following symptoms
- Bad vision or vision loss
- Lower levels of certain hormones
- A combination of the above
Pituitary tumors that do make hormones are called 'functioning tumors', they can cause a variety of signs and symptoms depending on the hormone they produce.
Depending on the size and type of tumor, the tumor can be removed via surgery and/or can be treated with medication or sometimes radiation therapy.
Within UNCH the LUMC is a national and European reference centre for pituitary tumors. More information (in Dutch) can be found on the LUMC website.
