Pituitary tumor

A pituitary tumor is an abnormal growth of cells in the pituitary gland, a tiny pea-sized gland located at the base of the brain that produces hormones controlling many body functions like growth, metabolism, and reproduction. Most pituitary tumors grow slowly and are benign, meaning they don't spread to other parts of the body, though they can cause problems by pressing on nearby structures or producing excess hormones that disrupt the body's chemical balance. These tumors are relatively common, affecting about one in every thousand people, and can often be managed with medication, radiation, or surgery depending on their type and severity.
