What are nodules?

1. Large areas of swelling

2. Referred to as tumors, but smaller

3. Fluid-filled blisters

4. Skin discolorations

The correct answer is: Referred to as tumors, but smaller

Nodules are defined as solid, raised lumps that can vary in size but are typically larger than a centimeter. They are often referred to as tumors or abnormal growths, but they are distinct from tumors in that they can be benign and not necessarily indicate cancer. They differ from larger areas of swelling, as swelling can occur for various reasons, including inflammation or injury, and it does not imply a solid structure. Fluid-filled blisters represent a different kind of skin lesion, typically characterized as vesicular lesions rather than solid masses, while skin discolorations refer to changes in the color of the skin without a raised structure. This makes the option regarding nodules being smaller tumors the most accurate among the choices provided.
