Country singer Bonnie Brown of sibling trio The Browns, due to be inducted into the Country Music Hall of Fame later this year, announced on Monday that she has been suffering from lung cancer, according to The Associated Press.

Brown, 78, said that she was diagnosed with stage four adenocarcinoma right lung cancer. Her brother, Jim Ed Brown, passed away after battle with cancer in June this year.

"It comes with great sadness that I have been diagnosed with stage four adenocarcinoma right lung cancer," Brown said, according to Reuters. "This news came as a shock to our family as we are still mourning the loss of my big brother."

However, Brown is very positive about her prognosis.

"I have full faith in my oncologist and the many specialists at CARTI in Little Rock, and I trust in them to determine the best path to my full recovery. I am surrounded by the love and support of my family and I am determined to live many more years," she said, according to Billboard.

The group, including older sibling Maxine, grew up together on a family farm in Arkansas and were known for hits like "The Three Bells," which topped the Billboard country chart for 10 consecutive weeks, "Here Today and Gone Tomorrow" and "I Heard the Bluebird Sing."

The Browns were chosen to be inducted into the Hall of Fame in ceremonies on Oct. 25.
