Roundtree faced and overcame yet another health issue in 1993. He discovered a tumor on his chest while filming a scene in Costa Rica. He had a double mastectomy and a breast cancer diagnosis as a result of that.
"You have breast cancer, the doctor told me," Roundtree said to ABC News in 2007. It wasn't until later that I learned about the breast cancer aspect. It was unbelievable to me.

Gabrielle Union, Roundtree's co-star in "Being Mary Jane," responded to his passing on X:
It was a dream to work with Richard Roundtree. Spending time with him and our Being Mary Jane family was always a blast, filled with laughs and the greatest stories. People would practically race over to see him because he was always the coolest dude in the room with the BEST vibes. We all adored him and he was the best.
Comedian Loni Love also shared her thoughts on Roundtree's passing on X (formerly Twitter).
"Sad to learn of Richard Roundtree's demise... At a period when there were few main Black men in movies, he was fantastic as John Shaft. He made being a detective look attractive and cool. Get plenty of rest. My sympathies to his family.
