Tina Knowles' new memoir "Matriarch" is out now, and she is sharing more details about her life, including a battle with breast cancer.

Tina Knowles, mother of Beyonce and Solange and author of a just-released memoir, revealed this week that she had been treated for stage 1 breast cancer last July. She noted how lucky she felt to have had the cancer discovered early after initially forgetting to reschedule a mammogram that had been canceled due to COVID.
