Mathew Knowles is fighting breast cancer.

The man who’s best known for the years he spent managing his superstar daughters Beyonce and Solange announced the news during a sit-down interview with Michael Strahan for Good Morning America that will air Wednesday.

A short teaser was released on Twitter on Tuesday and in it, we see Bey’s father opening up to Strahan about his diagnosis.

“How was it to tell your family about the diagnosis?” Strahan asks Knowles in the snippet.

So far, information about the diagnosis is scarce, but we’re sure more details will come out during the exclusive interview.

October is breast cancer awareness month, and most people tend to believe the disease only affects women. Knowles’ case is a reminder that the disease also affects men, particularly older men.

 Beyonce’s daddy Mathew Knowles is producing a Destiny’s Child musical

Back in April, Matthew Knowles announced plans to produce a musical about Destiny’s Child. 

“I want to pull back the curtain,” Knowles said in a statement posted on his website. “I feel it’s time to give the world an opportunity to hear, see and feel the victories and failures that I’ve had as a husband, father and manager who risked everything in pursuit of fulfilling dreams – those of mine and others.”

According to Knowles, the production is being developed for Broadway and London’s West End and is slated to premiere in 2020 in Houston, TX.
