Bonnie Brown, best known as a singer in country group The Browns, announced she has lung cancer on Monday in a statement to the Associated Press.

Brown, 78, told the outlet she was diagnosed with stage four adenocarcinoma right lung cancer. Her brother and co-band member Jim Ed Brown died from cancer this June. Next month, the group is due to get inducted to the Country Music Hall of Fame.

“I am surrounded by the love and support of my family and I am determined to live many more years,” Brown said in a statement.

The Browns’ major crossover hit “The Three Bells,” took over the airwaves in 1959 and hit No. 1 on the Hot 100 that year. “The Old Lamplighter” peaked at No. 5 in 1960, and “Scarlet Ribbon (For Her Hair)” hit No. 13 in the same year.
