LOS ANGELES • A cancer facility in the United States has been named after Britney Spears after she donated US$1 million (S$1.38 million) to it from concert-ticket sales.

The Nevada Childhood Cancer Foundation will open its new Britney Spears Campus next Monday to serve paediatric and adult patients.

"There are many things I've done in my career that I am proud of, but none more than this," Spears, 35, was cited by Us Weekly as saying.

"The fact that I was able to use my celebrity status to raise the money to build this incredible facility to help sick children and their families when they need it the most not only brings many tears to my eyes, but really brings tremendous meaning to this amazing journey that I have been on."

She added that "my aunt Sandra died of cancer and I know the devastating effects that this terrible disease brings upon its victims and their loved ones, but when it happens to innocent young children, there's literally nothing I can think of (that is) worse than that".

The proceeds came from ticket sales to her shows at Planet Hollywood Las Vegas Resort & Casino, where she has held a residency that started in 2013 and will end on Dec 31.
