'tumorigenic' originates from Latin, specifically the word 'tumor,' where 'tumor' meant 'swelling' and the suffix '-genic' from Greek 'genēs' meant 'born of or produced by.'

'tumor' transformed from the Latin word 'tumor' and eventually became the modern English word 'tumor.' The suffix '-genic' was added to form 'tumorigenic.'

Initially, it meant 'related to swelling,' but over time it evolved into its current meaning of 'capable of causing tumors.'
