October is National Breast Cancer Awareness Month and with news that Mathew Knowles has been diagnosed with breast cancer, it’s clear that this disease does not discriminate against gender. On Wednesday (Oct. 2), the music producer and former Destiny Child’s manager was a guest on Good Morning America sharing his own personal story. In a sit-down with  Michael Strahan he opened up about what having breast cancer means to him and when he first noticed that something was wrong. “I noticed because I wear white T-shirts. I had a dot of blood on my T-shirt.The first day I was like “Oh, OK, no big deal … maybe it’s something that just got on my T-shirt.” Second day I looked and the same thing and I was like, “Eh … interesting.” We also shared that he had a robust family history of this disease, but was confused about what that meant for him.
