Beyoncé and her sister Solange Knowles were tested for the breast cancer gene, after their father Mathew revealed his shock diagnosis.
The 67-year-old opened up about being diagnosed with breast cancer on Good Morning America, and admitted he was worried his kids were at risk too.
Mathew said: “The first call was to my family, that was the very first call. Because this is genetics. It means my kids have a higher chance – a higher risk.”
“It also means my grandkids are a high risk,” he said, before adding, “They handled it like they should. They went and got the test.”
Speaking about his diagnosis, Mathew said he knew something was wrong after he noticed a recurring dot of blood on his shirts, and a mammogram later confirmed that he had breast cancer.
He underwent surgery at the end of July, and is now on the road to recovery.
Matthew said: “Things that used to be important to me aren’t important now. I just look at the world differently.”
“I have the BRCA2 [gene] that’s mutated. For the rest of my life I have to be very much aware and conscious. And do all of the early detection.”
“Constant mammograms. Constant prostate exams. Constant MRI. For the rest of my life.”
Mathew divorced Beyoncé’s mother Tina Knowles back in 2011 after 30 years of marriage, but the pair have remained amicable.
The 67-year-old is father to Beyoncé and Solange Knowles with his ex-wife, and also shares daughter Koi and son Nixon with his current wife Gena Avery.
