No, Kevin Costner has not confirmed that he has ear cancer. 

The actor has yet to confirm his medical situation, despite his disfigured left ear making the rounds on the internet.

To be clear, the recent uproar on his left year occurred after the premiere of a new episode of Yellowstone.

As a result, no information on this issue has been found on the internet.

As a result, his new ear and tooth appearance may be limited to the series plot.

The news that the actor has been diagnosed with cancer will shatter many hearts, especially given the severe consequence of his ear.
