Rihanna has donated $1.75 million to a Barbados hospital in memory of her grandmother, Clara “Dolly” Braithwaite. The Queen Elizabeth Hospital (QEH) will receive this funding exclusively for its radiotherapy department, which will be renamed the Clara Braithwaite Centre for Oncology and Nuclear Medicine.

Braithwaite died of cancer in June 2012. Radiotherapy is an important form of cancer treatment.

“This was my way of giving back to Barbados, in a form of philanthropy, by assisting the QEH in its continued modernization program,” Rihanna told E! news. “I believe that this will have a huge impact on the people of Barbados. This was all done to save lives or at least extend them.”

The pop princess attended the opening of the wing on Christmas Eve with her grandfather, later tweeting, “Me and grand pops in Barbados at the unveiling ceremony in memory of #granDolly at QEH.”

The singer also extended a helping hand to those in need earlier this year by throwing a listening party to benefit victims of Hurricane Sandy, in addition to donating sleeping bags to this cause.

This past September Rihanna first memorialized her dear “Gran Dolly” with a tattoo of the goddess Isis across her upper abdomen.
