Former British number one Elena Baltacha has revealed that she has been diagnosed with liver cancer.
In a statement, the Ukranian-born 30-year-old said: "I have recently been diagnosed with cancer of the liver.
"I'm currently undergoing treatment and fighting the illness with everything I have," she said in a statement.
At the age of 19, Baltacha was diagnosed with primary sclerosing cholangitis, a chronic liver condition which compromises the immune system.
Baltacha was highly popular figure on the tour before retiring last year after failing to overcome a series of injuries.
The daughter of former Ipswich, St Mirren and Inverness footballer, Sergei, spent 132 weeks as British number one, from December 2009 to June 2012.
She won 11 ITF titles and reached a career high ranking of 49 in 2010.
Boasting wins against the likes of Li Na and Francesca Schiavone, Baltacha competed for Britain 39 times in the Fed Cup from 2003 to 2012.
She was also part of Team GB at London 2012, losing to Ana Ivanovic in the second round.
After her retirement, Baltacha set up an academy for junior players in Ipswich.
Fed Cup captain Judy Murray told BBC Sport: "She's a determined, upbeat person and everyone around her is positive."
