Nodule vs. Cyst: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 4, 2024
A nodule is a small, solid, often hard growth within body tissues, while a cyst is a sac-like structure filled with fluid, air, or other substances.

Key Differences

A nodule is a small, firm lump in body tissues, often resulting from inflammation, infection, or a tumor. Cysts, in contrast, are typically fluid-filled sacs that can form in various parts of the body due to various causes, including blockages of ducts, infections, or genetic conditions.

Nodules are generally solid and can be benign or malignant, depending on their cause and nature. Cysts are usually benign and characterized by their encapsulated structure, filled with fluid or semi-fluid content.

The texture of nodules is typically harder and more solid compared to cysts. Cysts, owing to their fluid content, often feel softer and can be movable under the skin.

Nodules can occur in various body parts, including the lungs, thyroid, and under the skin, and may or may not be symptomatic. Cysts can also appear in multiple locations like the skin, ovaries, and kidneys, and their symptoms depend on the size and location.
