An adrenal nodule is an abnormal growth on one or both of the adrenal glands, and they are often non-cancerous. These nodules typically do not produce hormones.
Understanding Adrenal Nodules
Adrenal nodules are relatively common, and most are discovered incidentally during imaging tests performed for other reasons. While the term "nodule" can sound alarming, it's important to understand that most adrenal nodules are benign (non-cancerous) and don't cause any symptoms.
Key Characteristics of Adrenal Nodules
Here's a breakdown of some important aspects:
-
Abnormal Growth: Adrenal nodules represent a deviation from the normal tissue structure of the adrenal gland.
-
Often Non-Cancerous: The vast majority of adrenal nodules are benign.
-
Typically Non-Functioning: Most nodules do not produce excess hormones, meaning they don't disrupt the body's hormonal balance. However, some nodules can be "functional," producing hormones like cortisol, aldosterone, or androgens.
Further Information
The adrenal glands are small, triangular-shaped glands located on top of each kidney. They are responsible for producing a variety of hormones that are essential for regulating many bodily functions, including metabolism, blood pressure, and the immune system.
