Daniela Klemenschits dies from cancer at 25

SALZBURG, Austria -- 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.

Daniela had several tumors removed and required expensive medical care. Roger Federer, Marat Safin, Justine Henin, Amelie Mauresmo, Martina Hingis and others donated items for an online auction in June to raise funds for her treatment.

The Klemenschits sisters won 20 titles on the ITF circuit. Although they didn't win a WTA Tour event, they entered the top 100 of the WTA doubles ranking in 2005.
