Tina Knowles (pic) is spreading the word about the need for women to get their scheduled mammogram every year.

In a new interview with People, the mother of global megastar Beyonce, 43, and singer Solange, 38, revealed her private battle with breast cancer in 2024. This is the first time she’s opened up publicly about her life-changing ordeal.

“It’s important not to slack on your mammograms,” the author of new memoir Matriarch told People. Knowles, 71, said doctors discovered Stage 1 cancer in her left breast last July. She was told the news right after she and Beyonce launched their award-winning haircare line, Cecred.
