Many celebrities have chosen to keep their medical conditions hidden from the public eye.
Health troubles can be complicated and scary, so for most people, they are best dealt with privately.
While celebrities can often be quite open about many other aspects of their lives, health-related issues can be a different story.
Many of these entertainers push forward despite their secret diagnosis, continuing to work on their upcoming projects without anyone knowing the harrowing experiences they are going through. This was true of Chadwick Boseman, who filmed several major films all while battling colon cancer. Fans only found out about his struggle after his unfortunate passing last month.
For others, they are thankfully able to persevere and open up about their health issues in their own time. Celebrities like Selena Gomez, Michael J. Fox and Emilia Clarke have gone on to support and aid others who are battling their same ailments.
