The process of forming or producing tumors in the body.
Researchers are studying tumorigenesis to understand how cancer develops.
Tumorigenesis → It is formed from "tumor" (from Latin *tumor*, meaning swelling or mass) and "-genesis" (from Greek *genesis*, meaning origin or creation). The word refers to the process of the formation or creation of a tumor.
Think of 'tumor' as a swelling and '-genesis' as the process of creation — together, they describe the process of creating a tumor.
