Bonnie Brown of sibling trio the Browns has been diagnosed with Stage IV Adenocarcinoma in her right lung.

Brown broke the sad news on Monday (Sept. 28) at a luncheon at the Country Music Hall of Fame and Museum.

"It comes with great sadness that I have been diagnosed with Stage IV Adenocarcinoma, right lung cancer," she says in a statement. "I have recently undergone tests to determine the best type of treatment for this horrible disease. This news came as a shock to our family as we are still mourning the loss of my big brother, Jim Ed, who passed away from the same cancer in June.

"As Jim Ed said at the announcement of our induction into the Country Music Hall of Fame earlier this year, ‘Cancer is no fun,'" Bonnie Brown adds, "and I agree."

Though Stage IV cancer is devastating news, Brown is keeping a positive attitude about the diagnosis.

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

Brown, her sister Maxine Brown and brother Jim Ed Brown, are being inducted in the Veteran's Era category at the Country Music Hall of Fame this year. The trio was created in 1955, and hits like "Here Today and Gone Tomorrow" and "I Take the Chance" led them to country music fame. They were inducted into the Grand Old Opry in 1963 and disbanded in 1967, with Jim Ed Brown then beginning his solo career.

Jim Ed Brown went into remission earlier this year, after being diagnosed with lung cancer in September of 2014. However, the disease returned, and he died on June 11, at 81 years old.

Bonnie Brown asks for prayers and good wishes, and fans can send a get-well card to the singer at PO Box 233, Dardanelle, Ark., 72834-0233.
