Adrenal tumors are benign or malignant growths that occur in the adrenal glands. The majority of adrenal tumors have unknown causes. Adrenal tumors can be surgically removed.

The adrenal glands are located above the kidneys and are also known as the suprarenal glands. The adrenal gland consists of two parts: the adrenal cortex and the medulla. The adrenal cortex secretes cortisol and aldosterone hormones, while the adrenal medulla produces dopamine, epinephrine, and norepinephrine.

Adrenal tumors can be either malignant or benign. The majority of adrenal tumors are benign. They often do not cause any symptoms and are incidentally discovered during the evaluation of a patient presenting with unrelated abdominal pain, through computed tomography (CT) or magnetic resonance imaging (MRI) scans. Such incidentally discovered masses are called adrenal incidentalomas. They are classified as non-cancerous (benign) or cancerous (malignant), and can also be classified as functional or non-functional. Functional tumors cause excessive production of normal adrenal hormones.

Are there any risk factors that contribute to the development of an adrenal tumor?

The causes of most adrenal tumors are unknown. Certain hereditary conditions are associated with an increased risk of developing adrenal tumors. These hereditary conditions include:

– Carney complex
– Li-Fraumeni syndrome
– Multiple endocrine neoplasia type 2
– Neurofibromatosis type 1
