The Real Housewives of Dallas alum D'Andra Simmons has been diagnosed with breast cancer. "Today is the day! I didn't think I would be the recipient of care at the UTSW Simmons Cancer Center my uncle Harold Simmons and his Foundation established almost 30 years ago, but now I have breast cancer," Simmons, 56, captioned an Instagram post on Tuesday, July 29. "I am truly grateful to have such an excellent care team in place. I'm the 3rd woman on my mother's side of the family to be diagnosed with breast cancer ... that we know about.
