Tina Knowles Breaks 
Silence on Ex Mathew 
Knowles' Cancer Diagnosis On the first day of Breast 
Cancer Awareness month, 
Beyonce's father revealed 
he is battling breast cancer. Mathew Knowles made 
the announcement during 
an interview on 'Good 
Morning America' last week. The former Destiny's Child 
manager is currently cancer free. He had three 
lymph nodes removed. His former spouse, Tina, 
says she's thankful the
