Neil Cavuto, host of "Your World," paid tribute to Buttner on his show.

"I have some very sad news to share with you today: Our Brenda Buttner has passed away," he revealed. "Now, many of you know her as the unflappable host of 'Bulls and Bears,' but she was much more. Allow me now to tell you how much more."

Reactions to Brenda Buttner's death:

"She was a Rhodes Scholar, but she'd never mention it," he explained. "Near the top of her Harvard class, but she would never ever say it. [...] All that smarts stuff is in her files, but the more important things filled her heart."

Cavuto went on to explain that Buttner had a passion for motorcycles, animals and her two daughters. At one point, she put her career in journalism on hold to edit a motorcycle magazine.

Celebrities that died in 2016:

"No bravado -- just brave," he continued. "Incredibly brave. You never knew what was going on in her life and how much she was going through in her life -- just that, in her sickest moment when she was battling an unrelenting cancer, there was Brenda cheering you on."

"She took stock of life much more than any stock in life. It's what separated her from everyone else in this business. Not just dollars, you see, Brenda had depth," Cavuto said. "Let it be known that Brenda Buttner made us want to watch a business show with heart. Her heart, her spirit. She democratized dollars and just made sense."
