Beyonce's father Mathew Knowles has revealed he was diagnosed with breast cancer earlier this year.

The 67-year-old appeared on Good Morning America on Wednesday where he said he is "doing really good" after having surgery at the end of July and added that he is following "all the steps for recovery".

The talent manager said he was prompted to go to the doctor after noticing small, recurring dots of blood on his shirt and on the bed sheets.

"I immediately went to my doctor, I got a mammogram, and then it was very clear that I had breast cancer", he explained.

When asked my GMA's Michael Strahan how he felt about the breast cancer diagnosis, which is rare for males, Knowles replied: "Of all the things I could get, why would I get this? From a man's perspective I'm thinking, why me?"

He said that he carries the BRCA2 gene which means he has "four things to be concerned about: prostate cancer, pancreatic cancer, melanoma and breast cancer."

"The rest of my life I have to be very much aware and conscious and do all of the early detection, constant mammograms, constant prostate exams, constant MRI scans, for the rest of my life", Knowles added.

The music executive said that members of his family, which also includes daughter Solange Knowles, have been tested for the disease following his diagnosis.

"The first call was to my family. Because this is genetic, it also means that my kids have a higher chance, a higher risk. Even my grandkids have a higher risk", he said. "And they handled it like they should. They went and got the test."

He added that he wanted to speak out about his diagnosis at the start of Breast Cancer Awareness Month to encourage more men to get tested for the disease.

He said that he wants to show men that "you can survive this, but it has to be early detection".

Knowles is best known for putting together the R&B group Destiny's Child, which launched his eldest daughter Beyonce to stardom. He also managed her solo career until 2011.

He divorced wife Tina Knowles, Beyonce and Solange's mother, in 2011, and he married second wife Gena Avery in 2013.
