Martina Navratilova has breast cancer

Former tennis champion Martina Navratilova has revealed she has been diagnosed with breast cancer.



Navratilova told US magazine People that she cried after finding out.



However, the report said her prognosis is excellent.



During her career, she won 18 Grand Slam singles titles, nine of them at Wimbledon.



The 53-year-old Navratilova says the disease had been detected early thanks to a routine mammogram.



The Prague-born former champion, who became a US citizen in 1981 and now has dual US-Czech citizenship, still plays tennis and competes in triathlons.



She played her last Wimbledon tournament in July 2006.
