Pituitary tumors are abnormal growths that develop in the pituitary gland, a small gland located at the base of the brain. These tumors can be either benign (non-cancerous) or malignant (cancerous) and may affect hormone production, leading to various health issues. Symptoms can include headaches, vision problems, and hormonal imbalances. Most pituitary tumors are classified as adenomas, which are benign tumors that can cause the gland to produce excess hormones. Treatment options often include surgery, radiation therapy, or medication to manage symptoms and hormone levels. Regular monitoring is essential for managing these tumors effectively.
