They tend to grow more slowly that more common (adenocarcinomas) cancers in the intestinal tract.

How prevalent are pituitary tumors/diseases?

Almost 20% may have pituitary tumors but most will remain undetected as they do not cause any symptoms. Those that grow large enough to cause symptoms due to size or secrete enough of one of many hormones that the pituitary normally secretes may need to be treated with medicines or surgery.

Dr. Tung T. Nguyen answered:

How serious is it to have pituitary tumors?

Varies

Chiari_malformation
Pituitary tumors can be large and compress the visual nerves. It is common for larger tumors to bleed. Tumors can release high levels of hormones, which would affect normal hormonal balance. If you have a tumor, you should see a neurosurgeon, who will have input from endocrinologists, ophthalmologists, etc., to help work up the tumor and decide the best course of treatment.

Dr. William Goldie answered:

Are all pituitary tumors the same?

Tough question

Pituitary_tumors
Tumors of the pituitary vary almost as much as the type of people who ask questions to Health Tap. Think of the pituitary as an attachment of the brain that receives information and sends messages in the form of hormones throughout the body. Abnormal growths can occur within and around this gland as well as excessive growth due to too much or too little information and hormone in and output.
