The Norwegian Royal Family has announced that Crown Princess Mette-Marit has successfully undergone a lung transplant. The 52-year-old princess had been battling pulmonary fibrosis, a serious and incurable condition. This disease causes scarring of the lung tissue, which significantly impairs the ability to breathe. Due to the severity of her illness, the wife of Crown Prince Haakon had been relying on oxygen equipment for her daily life. The medical procedure was reported as a success by the royal household. This development marks a critical turning point in the princess's long-term health struggle.
