Mathew Knowles knows firsthand the power of early detection, which is why he urged his daughters, superstar singers Beyoncé and Solange, to undergo BRCA genetic testing after he was diagnosed with breast cancer in July.

The BRCA gene test is a blood test that identifies harmful and potentially cancer-causing mutations in either one of the two breast cancer susceptibility genes — BRCA1 and BRCA2. Knowles, 67, a music executive who teaches at Prairie View A&M University in Texas, tested positive for the BRCA2 gene mutation while doctors were diagnosing his condition over the summer.

Since mutations in the BRCA2 gene can be inherited, Knowles tells PEOPLE in an interview for this week’s issue that “Beyoncé and Solange have an increased risk” of having his same mutation.

But, he notes, “They have an exceptional team, and they’ve gone through precautionary measures,” including the BRCA gene test.

“They have taken care of that, it’s simple testing,” he says. “And they’re moving on.”
