The singer and dancer recently enjoyed great success in the musical Sweet Charity.
In a statement, Grönvall, who’s married and has three children, said that she was cancelling her planned summer tour of Scandinavia after discovering a lump on her breast. She said she would be operated on soon, and would then face follow-up treatment.
”To be hit by this turns your whole life upside down, not least when you have a family with three children, as I do,” she said.
She asked the press not to request any interviews with her about the illness. ”I’m going to take it one day at a time, and devote the near future to getting through whatever is needed, together with my family, and hopefully getting better soon.”
