Nine-time winner of Wimbledon Martina Navratilova, who also previously suffered from cancer, has paid tribute to Elena Baltacha, saying she fought "to the end" but "sometimes cancer wins".
She said: "Elena Baltacha was a great fighter on the tennis court.
"We as tennis players always worry about our bodies, trying to keep injuries at bay. But cancer - you can't prevent that and you can't rehab it either and no matter how much of a fighter you are, sometimes cancer wins.
"Elena was taken from the world much too soon - fighting to the end and we will miss her."
An all-star line up of fundraising exhibition matches for a Rally Against Cancer charity even will take place next month in honour of British tennis star Elena Baltacha.
Her childhood friend Andy Murray had committed to play in the event along with the likes of Martina Navratilova, and Tim Henman, and the money raised will go to the Elena Baltacha Academy of Tennis and the Royal Marsden Cancer Charity.
Her agent and friend Eleanor Preston said the fundraiser next month will be an opportunity to celebrate everything the tennis star achieved.
British tennis has lost "a shining light" following the death of former women's number one Elena Baltacha at the age of 30, the Lawn Tennis Association has said.
The sports star was diagnosed with the illness in January, just two months after retiring from tennis and only weeks after she married her long-time coach Nino Severino.
The Lawn Tennis Association's head of women's tennis Iain Bates said in a statement: "Today we have lost a shining light from the heart of British tennis - a true role model, a great competitor and a wonderful friend.
We have so many special memories to cherish, but this leaves a gaping hole for everybody in both British and women's tennis, and words simply cannot express how saddened we are by this news."
