Former Austrian doubles player Daniela Klemenschits died Wednesday after battling cancer. She was 25.

The Austrian tennis federation said Wednesday that Klemenschits and her twin sister Sandra were diagnosed with a rare form of abdominal cancer in January last year, forcing them to retire.

They played doubles on the WTA Tour and the ITF women's circuit until 2006.

PLEASE  donate some money to help Sandra beat the cancer! They need you! Any amount will help!
