According to TMZ, Dolly Parton secretly flew to Frankfurt, Germany, about a year before her August 25 death at age 80 to receive an experimental cancer treatment. Sources familiar with the situation said the country music icon stayed overseas for roughly one week and believed the treatment helped bring back her strength. TMZ's reporting does not identify the type of cancer Dolly Parton battled or explain what the procedure involved. The reported trip was kept private, with Dolly Parton traveling by private jet before returning home. What Do We Actually Know About the Treatment? The overseas treatment remains largely undocumented, and the claims come from sources familiar with Dolly Parton's situation rather than a public medical statement. Dolly Parton reportedly felt the treatment had worked, but no details have been released about its medical results or long term impact. Dolly Parton's death reportedly stunned people close to her, even though members of her inner circle knew she had been sick. After loved ones learned she had been hospitalized and was doing poorly, they rushed to Nashville, where Dolly Parton's family held a private ceremony and laid her to rest at Woodlawn Memorial Park and Mausoleum.
