Pituitary Tumor

Before defining it, it helps to know when to investigate: persistent headaches, changes in vision, or hormonal disturbances can prompt a workup. A pituitary tumor is a growth in the pituitary gland, a small gland at the base of the brain that regulates many of the body's hormones; most of these tumors are not cancerous.

Common symptoms: Headache, vision changes, and hormonal disturbances that can affect growth, weight, or energy.

Common causes: It usually involves a growth of the gland's own cells, whose exact cause is not always known.

Which specialist treats it? The endocrinologist addresses the hormonal aspect, with support from the internist, the pediatrician in children, and the general practitioner as the first point of contact. When symptoms suggest this type of condition, the prudent step is to consult a professional who can order the necessary tests.
