Signs of a pituitary tumor include problems with vision and certain physical changes. Signs and symptoms can be caused by the growth of the tumor and/or by hormones the tumor makes or by other conditions. Some tumors may not cause signs or symptoms. Check with your doctor if you have any of these problems.
Sometimes, a pituitary tumor may press on or damage parts of the pituitary gland, causing it to stop making one or more hormones. Too little of a certain hormone will affect the work of the gland or organ that the hormone controls.
The following signs and symptoms may occur:
Headache.
Some loss of vision.
Loss of body hair.
In women, less frequent or no menstrual periods or no milk from the breasts.
In men, loss of facial hair, growth of breast tissue, and impotence.
In women and men, lower sex drive.
In children, slowed growth and sexual development.
