# Renal Mass and Localized Renal Tumors

The word renal means kidney. The words "tumor" and "mass" mean abnormal growths in the body. A renal mass, or tumor, is an abnormal growth in the kidney. Some renal masses are benign (not cancerous) and some are malignant (cancerous).

Archived from the 2024 edition

## Overview

One in four renal masses are benign. Smaller masses are more likely to be benign. Larger masses are more likely to be cancerous. Some tumors can be slow to grow while some can be aggressive. Aggressive tumors form, grow and spread very quickly.

Most diagnosed kidney growths are small and localized masses. Localized means that the tumor has not spread out from where it first started. Around 40% of kidney cancers are localized renal masses. Masses may be solid or cystic (having fluid). Most cystic masses are benign.
