Root Explanation

Oncogene is formed from "onco-" (from Greek "onkos", meaning mass or tumor) and "gene" (from Greek "genes", meaning born of or produced by). The word refers to a gene that has the potential to cause cancer, essentially a gene that can lead to the formation of a tumor.

Memory Tip

Think of 'onkos' meaning a mass or tumor, and 'gene' meaning something that is produced. This helps you remember that an oncogene is a gene that can lead to the formation of a tumor.
