Does using a rare candy cancel evolution for Pokemon?

Using a Rare Candy on a Pokémon does not cancel its evolution. Rare Candies are items in the Pokémon series that allow a Pokémon to instantly gain one level. When a Pokémon levels up, it may evolve if it meets the necessary criteria, such as reaching a certain level or learning a specific move. Using a Rare Candy can, therefore, speed up the process of evolving a Pokémon if it is close to the required level.
