Dolly Parton kept her cancer battle hidden from millions of fans — and even from some members of her own family — because she did not want the people she loved worrying about her during her final months.
The country music legend died Aug. 25 at age 80 following what her team described as a brief battle with cancer.
Now her younger sister, Stella Parton, is revealing why Dolly chose to keep the diagnosis so private.
“She did not want people sad,” Stella told Gayle King during an exclusive CBS Mornings interview.
Stella said only a limited number of relatives knew how seriously ill Dolly had become.
“Some of us knew, the ones of us that were closer,” she explained, adding that Dolly would not have wanted her enormous fan base frightened by news of her condition.
CBS has posted video from Stella’s interview with Gayle King, which can be watched here.
Dolly’s illness was not publicly identified as cancer until after her death.
According to her official website, Dolly died peacefully in Nashville on Aug. 25. Her family requested a small private service for immediate relatives and encouraged fans who wanted to honor her to support Dolly Parton’s Imagination Library.

CBS News reported that Dolly’s representatives said she died at Vanderbilt-Ingram Cancer Center surrounded by loved ones after a “brief battle with cancer.”
Neither Stella nor Dolly’s representatives have revealed what type of cancer she had.
And Stella made clear that she does not intend to change that.
During her CBS interview, Stella said Dolly never specifically gave the family permission to reveal the exact diagnosis.
Out of respect for her sister’s wishes, Stella said she does not believe it is her place to disclose private medical details Dolly chose to keep to herself.
The revelation also puts some of Dolly’s health troubles over the previous year into a different light.
In September 2025, Dolly announced that she was postponing a planned Las Vegas residency because doctors wanted her to undergo several medical procedures.
At the time, she described the issue only as “health challenges” and jokingly called the treatment her “100,000-mile check-up.”
She reassured fans that she was not retiring and planned to continue working from Nashville.
Months later, Dolly canceled the rescheduled Las Vegas performances altogether.
She publicly attributed her troubles to longstanding kidney stone problems along with complications affecting her immune and digestive systems. She said medication was helping but that side effects left her feeling too dizzy to safely perform onstage.
None of those public statements identified cancer as the reason for her health problems, and her family has not said when the cancer was diagnosed.
That distinction is important because there is no public confirmation that every health problem Dolly discussed before her death was related to cancer.
Even while her health declined, Dolly continued working.
Her longtime manager Danny Nozell said after her death that the superstar remained involved in projects until the end and had helped create a roadmap for her team to continue her work for years to come.
“Dolly worked up until the day she died,” Nozell said in a statement released through her official website.
Her final months followed an already emotional period in Dolly’s life.
Her husband of nearly six decades, Carl Dean, died in March 2025. Dolly later acknowledged that she had neglected some of her own health while dealing with the loss.
Stella said that despite what Dolly was enduring privately, her famous optimism remained intact.
She told CBS that she does not miss seeing her sister struggling or in pain because she believes Dolly had made peace with what was happening.
“I know she was at peace,” Stella said.
“She knew where she was goin’.”
Dolly’s death triggered tributes from across the entertainment world and from generations of fans who had followed a career stretching from the Grand Ole Opry to Hollywood.
Her influence also reached far beyond music.
Through the Imagination Library, Dolly helped provide hundreds of millions of free books to young children. She also famously donated $1 million toward coronavirus research at Vanderbilt University Medical Center, funding that supported work connected to Moderna’s COVID-19 vaccine.
Stella said the enormous response following Dolly’s death would have meant something deeply personal to her sister.
She believes Dolly would have been touched knowing that the affection she spent decades giving to other people was now being returned to the family she left behind.
For Stella, however, one part of Dolly’s final chapter will remain private.
Exactly what cancer claimed her life is something the family still has not disclosed — and unless Dolly specifically wanted that information released, her sister says it should remain Dolly’s business.
