Here are 7 well-known celebrities who successfully kept their major surgeries a secret.
1. Chadwick Boseman

Despite his health struggles, Boseman continued to work diligently behind the scenes to advance his career.
2. Emilia Clarke
Emilia Clarke , known for her role in Game of Thrones , shared a challenging part of her life when she had to undergo brain surgery between two seasons of the show.
