The story behind the word. Traced to Latin 'benignus', blending 'bene' (well) and '-gnus' (born). Originally used to describe generous rulers, medical doctors began using it in the 18th century to describe non-fatal health conditions.

Fun facts
- Even though benign tumors are non-cancerous, they can still cause health problems if they press on vital structures like nerves or blood vessels.
