Tina Knowles shares how a missed mammogram may have led to a delayed detection of breast cancer, and opens up about the support from her daughters, Beyoncé and Solange, niece Angie Beyincé, and bonus daughter Kelly Rowland.

Tina Knowles detailed how her daughters Beyoncé, Solange Knowles, plus Kelly Rowland supported her amid her breast cancer journey last year.

My doctor told me I had breast cancer. A small tumor in my left breast that was cancerous; the larger tumor in my right breast was benign, but it would also have to go,” Knowles wrote in her memoir, per Us Weekly.
