A teaser for the interview was posted on Tuesday to coincide with the first day of Breast Cancer Awareness Month.
Male breast cancer is rare and usually occurs in men over 60.
In the trail for the interview, Knowles is shown being asked how he broke the news to his family.
The entrepreneur and public speaker announced he would make “a special announcement” on Wednesday’s programme.
Knowles, a former Xerox salesman, is best known for putting together Destiny’s Child, the band that launched eldest daughter Beyonce to stardom. He also managed her solo career until 2011.
He divorced Beyonce and Solange’s mother Tina in 2011 and has since had two more children with his second wife Gena.
