Martina Navratilova has announced she is cancer-free, with Billie Jean King welcoming the "wonderful news".

Doctors believe the 66-year-old tennis great has beaten cancer for a second time, after previously overcoming breast cancer in 2010.

The Czech-American announced in January she had been diagnosed with throat and breast cancer, sparking an outpouring of well-wishes.

She is one of the most decorated players of all time, having won 18 grand slam singles titles between 1978 and 1990, plus a staggering 41 doubles slams.

Speaking to Piers Morgan on TalkTV, Navratilova said: "As far as they know, I'm cancer-free."

According to The Sun, Navratilova will have further preventative radiation treatment on her breast.

"Then I should be good to go," she said.

King, her friend and former tennis rival, was thrilled to learn Navratilova's health has taken a turn for the better.

She wrote on Twitter: "Such wonderful news from my dear friend, ⁦@Martina⁩. We are so happy for you!"

Speaking to Stats Perform prior to Navratilova's announcement, former ATP world number two Tommy Haas spoke of his admiration for the legendary left-hander, and wished for a full recovery.

"What she has done in women's tennis and her success, the way she also kind of showcased her athleticism, her focus, her dedication to the sport, the records that she's broken, the longevity of it too," Haas said, listing reasons to be an admirer.

He described her as "an icon on the tour", and hoped she would survive this year's worrying cancer scare.

"Obviously, when you read the news about anyone in the tennis world that has had some kind of impact, or a great career, it's always sad, and you send them a text message, and you wish them the best and a speedy recovery," said Haas, the Indian Wells Open tournament director.

"You hope that they found these situations early, just like with Chris Evert [who recovered from ovarian cancer], and that they get through this and that they have the loved ones and friends around them and support them and get back to what they enjoy doing in life.

"I think we all know, and realise that without health, you have nothing. It's nice to be a part of certain things that you're passionate about. And it's important, and it's great, but being healthy and doing the things that you want to do ultimately, is really what it comes down to."

Tennis great Chris Evert has revealed she is cancer-free, just over a year after she began her fight against the illness.

Evert began chemotherapy in January 2022 after she was diagnosed with ovarian cancer.

Doctors caught Evert's cancer early after she had a preventative hysterectomy following the death of her sister, Jeanne, from the same disease.

The 68-year-old, who concluded her course of chemotherapy last May, confirmed the positive news on Tuesday, writing for ESPN: "A year ago, I started a journey to protect myself and my loved ones from the risks associated with the BRCA-related ovarian cancer that took my sister Jeanne's life. 

"It is only because of the genetic road map my sister left behind and the power of scientific progress that we caught my cancer early enough to do something about it.

"My doctor said if left undiscovered, in four months' time I would probably have been Stage Three like Jeanne, with very few options. Instead, I was diagnosed with Stage Three ovarian cancer, and I immediately began six rounds of chemotherapy.

"Today, I'm cancer-free, and there's a 90 per cent chance that the ovarian cancer will never come back."

However, Evert added her "story isn't over" and confirmed that on December 1, a year to the day since her hysterectomy, she underwent a double mastectomy in order to reduce the risk of developing breast cancer.

Evert said she is "well on the road to recovery".

She explained: "I have one more surgery left to complete reconstruction. They say this part is easy, but I can assure you, the last five years have not been.

"As relieved as I will be to get to the other side of this, I will always have a heavy heart. I will never heal from losing Jeanne, and I will never take for granted the gift she gave me in the process.

"My sister's journey saved my life, and I hope by sharing mine, I just might save somebody else's."

Evert won 18 grand slam titles across her illustrious career and enjoyed an on-court rivalry with Martina Navratilova.

When Navratilova confirmed her own cancer diagnosis earlier this year, Evert was among those to offer their support.

Evert posted on Twitter: "Thinking of @Martina today and supporting her journey, like she did mine, with love and prayers. This is a woman who takes on challenges with strength and resilience…You got this, Martina."

Chris Evert has backed her long-time rival and friend Martina Navratilova to win her latest cancer battle.

American tennis great Evert, who completed her own course of chemotherapy treatment in May after being diagnosed with ovarian cancer, said Navratilova's "strength and resilience" would stand her in good stead.

Navratilova has been diagnosed with throat and breast cancer, she announced on Monday. The Czech-American successfully underwent treatment for breast cancer in 2010 and has said the condition is "serious but still fixable" this time.

Evert's battles with Navratilova in the 1970s and 1980s provided one of the all-time great tennis rivalries.

Both women ended their careers with 18 grand slam singles titles, with Navratilova triumphing a record nine times at Wimbledon. Only Steffi Graf (22) and Serena Williams (23) have won more singles majors among women in the Open Era.

Evert posted on Twitter: "Thinking of @Martina today and supporting her journey, like she did mine, with love and prayers. This is a woman who takes on challenges with strength and resilience…You got this, Martina."

Former US Open champion Tracy Austin sent "prayers and hugs", adding: "Don’t know too many stronger, I know you got this my friend."

Navratilova's long-time former doubles partner Pam Shriver added: "@Martina knows how to put together a winning team. While the news today is difficult, Martina understands how to compete, and take care of herself.

"Her loving family and many friends are ready to support her journey one day at a time. You have this partner!"

Ons Jabeur, who was runner-up at Wimbledon and the US Open last season, said she was "sending my love and my support".

Martina Navratilova said she is "not done yet" after it was confirmed she had been diagnosed with throat and breast cancer.

Navratilova is one of the most decorated tennis players of all time, having won 18 grand slam singles titles between 1978 and 1990.

She successfully underwent treatment for breast cancer in 2010, but it has been revealed she is once again battling the illness.

A representative described Navratilova's prognosis as "good", and the 66-year-old said the disease was "serious but still fixable".

Navratilova has pledged to fight, posting on Twitter: "Needless to say my phone and Twitter are both blowing up.

"I will say again – thank you all for your support and I am not done yet."

The Czech also received support from Billie Jean King, who tweeted: "Martina is as brave as she is strong. She has fought this battle before, and she is in our thoughts and prayers."

Billie Jean King insists Martina Navratilova is "as brave as she is strong" after the latter was diagnosed with throat and breast cancer.

Navratilova is one of the most decorated players of all time, having won 18 grand slam titles during a glittering career.

The 66-year-old underwent successful treatment for breast cancer in 2010, but it has now been confirmed she is battling the illness again.

Navratilova said the diagnosis is "serious but still fixable," while a representative confirmed she will start treatment later this month and subsequently not attend the Australian Open.

King, a 12-time major winner, offered her support.

"Martina is as brave as she is strong," the 79-year-old tweeted.

"She has fought this battle before, and she is in our thoughts and prayers."

Martina Navratilova has been diagnosed with throat and breast cancer, though a representative described the prognosis as "good".

Navratilova won 18 grand slam singles titles between 1978 and 1990, making her one of the most decorated players of all time.

She underwent successful treatment for breast cancer in 2010, but it has now been confirmed she is battling the illness again.

Navratilova said: "This double whammy is serious but still fixable, and I'm hoping for a favourable outcome.

"It's going to stink for a while but I will fight with all I have got."

Navratilova, 66, was due to travel to Melbourne this month to work on coverage of the Australian Open, a tournament she won three times.

But with her treatment due to start later in January, it has been confirmed she will not be in attendance.

A statement from a representative explained: "The prognosis is good and Martina will start her treatment this month.

"The cancer type is HPV and this particular type responds really well to treatment.

"Martina noticed an enlarged lymph node in her neck during the WTA finals in Fort Worth. When it didn't go down, a biopsy was performed, the results came back as stage one throat cancer.

"At the same time as Martina was undergoing the tests for the throat, a suspicious form was found in her breast, which was subsequently diagnosed as cancer, completely unrelated to the throat cancer.

"Both these cancers are in their early stages with great outcomes.

"Martina won't be covering the Australian Open for Tennis Channel from their studio but hopes to be able to join in from time to time by Zoom."

WTA world number one Iga Swiatek thanked Roger Federer for "everything you've done and everything you are for our sport" after the Swiss great announced his retirement.

Federer confirmed on Thursday that he would bring his illustrious playing career to a close after the Laver Cup.

The 41-year-old will bow out with 20 grand slam titles to his name, a feat bettered by only two male players – Rafael Nadal and Novak Djokovic.

Swiatek, meanwhile, won her third major title last week, defeating Ons Jabeur in straight sets to clinch the US Open, following her successes at Roland Garros in 2020 and earlier this year.

"I just want to thank you for everything you've done and everything you are for our sport," 21-year-old Swiatek tweeted in response to Federer's announcement.

"It's been a privilege to witness your career. I wish you all the best." 

Swiatek followed her post with a goat emoji, signifying that Federer is the greatest of all time.

Chris Evert, a former world number one, also joined the tributes to Federer, tweeting: "He was the epitome of a champion; class, grace, humility, beloved by everyone…and he elegantly mastered the sport like no other…Good luck to you, @rogerfederer don't go too far!"

Martina Navratilova, an 18-time major winner, posted: "What a heartfelt message, full of love, life, hope, passion and gratitude. Which is exactly how Roger played the game we love so much. Thank you thank you thank you, for all the magic!!!"

Serena Williams will go out with "full force" when she begins her final US Open campaign before retiring, according to Chris Evert.

Williams will have one last chance to match Margaret Court's all-time record of 24 grand slam singles titles at Flushing Meadows, as well as an opportunity to wave goodbye to her adoring fans on home soil.

While a challenge for the trophy looks highly improbable for Williams this time around, fellow six-time US Open winner Evert suspects the 40-year-old will take some shifting from the draw.

According to Evert, "the edge is off" when it comes to Williams and her remaining tennis goals, meaning she has reconciled herself to the likelihood of finishing her career with 23 singles majors.

Williams has revealed family matters and business interests were key to her decision to "evolve away" from the sport, and with her on-court returns diminishing, now seems the time to head in that direction.

Yet Evert can see Williams, who faces Danka Kovinic in round one in New York, giving a good account of herself during her US Open swansong.

"Serena isn't coming out to play her last match; she's coming out with full force," Evert said on ESPN. 

"The way she's been practising this week, she's here to compete, she's here to win, and I don't even think she's thinking about retirement at this stage."

Williams holds a 106-14 win-loss record in singles at the US Open. Her match wins tally at Flushing Meadows is the highest by any woman at the competition in the Open Era, and only Martina Navratilova has more at a single slam, achieving an astonishing 120 victories at Wimbledon.

Williams and Evert lead the way in women's US Open titles in the professional era (since 1968), and regardless of final grand slam tallies, there will always be debate over who ranks as the greatest player of all time.

Williams certainly has a strong case, yet Navratilova (1,442), Evert (1,309) and Steffi Graf (900) all won more WTA-level matches than Williams (856), who often played a limited schedule.

Court has the most grand slam titles on the women's all-time list, with a remarkable haul of 64 when women's doubles and mixed doubles are included. Navratilova is next with 59, before Williams and Billie Jean King sit joint third with 39 majors apiece.

Scheduling self-preservation has allowed Williams to play on for so long, and John McEnroe has raised the question of what might happen if his fellow American surprises herself by clinching a seventh Flushing Meadows triumph. 

"If she did happen to win this, don't you think it'd be tempting to go and break the record?" McEnroe asked.

Four-time US Open singles champion McEnroe added: "I think she's accepting, as much as Serena Williams can, that she's not going to win this.

"Maybe deep down she's found some sort of belief that maybe somehow, if she gets the right set of situations going, she can make a real run."

More realistic, in McEnroe's mind, is the prospect of Williams and sister Venus having a deep run in the doubles after they were handed a wildcard.

As a partnership, the siblings have won 14 grand slam doubles titles, never losing in a final at the majors.

"The two of them in doubles, where they're covering half the court and they're still able to do their thing, that would be a hell of a way to go out," McEnroe said.

Martina Navratilova said she was "gutted" to miss Wimbledon's Centre Court centenary celebration after testing positive for COVID-19 on Sunday.

The nine-time champion was absent from a parade of champions, and in a series of posts on social media she explained why she had to sit it out.

Past winners were introduced to the main show court's middle Sunday crowd, with the one-time champions going first, all the way through to eight-time Wimbledon king Roger Federer.

Navratilova would have come out last of all, as the most successful singles player in Wimbledon history, but she was unable to take part. Including doubles, Navratilova won 20 slam titles at Wimbledon.

"Unfortunately I will miss it as I just tested positive this morning," she wrote on Twitter shortly before the ceremony. "Am so bummed!!!! I am gutted I can't be there."

Confirming she had the coronavirus, Navratilova wrote: "Yup, got it here for sure… oh well. So wanted to be on that court with so many champions of our sport."

Asked how she was feeling, the 65-year-old Czech-born American added: "Not too bad so far- wouldn't want to play tennis but ok… fingers crossed."

A host of greats of the game delighted the crowd, with stars of the women's tour including Navratilova's former great rivals Chris Evert and Billie Jean King, along with Margaret Court and Venus Williams, while Federer was joined by a field of fellow men's superstars that included Rod Laver, Novak Djokovic, Stefan Edberg, Rafael Nadal and Andy Murray.

Three-time former champion Boris Becker was another notable absentee, after the German was jailed in April for offences relating to his 2017 bankruptcy. Seven-time winner Serena Williams also missed the event, after her first-round defeat.

Navratilova has been working at Wimbledon during the championships, notably appearing as a member of the BBC broadcast team.

Rafael Nadal fended off a second early test of his Wimbledon mettle as he took four sets to see off Ricardas Berankis on Thursday.

Just as in his opener against Francisco Cerundolo, Nadal dropped the third set of this match, but he regrouped, as he had two days earlier, to finish it in four.

A 6-4 6-4 4-6 6-3 victory for the 36-year-old will do the job for round two, but it was laboured at times on Centre Court from Nadal, a day after title favourite Novak Djokovic delivered a masterclass against Thanasi Kokkinakis.

Australian Open and French Open champion Nadal sealed it with an ace, his 16th consecutive win in a grand slam match, and the lack of polish at this early stage can be forgiven, given his lack of preparation on grass as he underwent treatment on his troublesome foot.

World number 106 Berankis forced breaks to lead early in the second and third sets, and although the Lithuanian was pegged back quickly enough by Nadal on the first occasion, he held his nerve to take the third set.

A rain delay came when Nadal was 3-0 clear in the fourth set, and that was only an inconvenience, Nadal wasting little time in finishing the job.

With Matteo Berrettini and Roberto Bautista Agut both pulling out of Nadal's half of the draw due to COVID-19, and Denis Shapovalov losing on Thursday to Brandon Nakashima after reaching the semi-finals last year, it is hard to see who might deny the Spanish two-time champion a place in the final, unless Nick Kyrgios or Stefanos Tsitsipas fancy the task. Italian Lorenzo Sonego will be the next to try.

Nadal said: "Every day is a challenge. That's the truth. I didn't play much on grass in the last three years. I need to improve, but I think the fourth set was much better. I think it was a good level of tennis in that set and the serve worked much better at the end of the match and I was able to play more aggressive, while at the beginning there were too many mistakes.

"It's important for me to accept things are not perfect and just keep working, be humble and accept the challenge."

Data slam: Going past Martina

Nadal took his total of singles grand slam wins to 307 with this victory, taking him one ahead of Martina Navratilova, the nine-time Wimbledon champion.

He moves up to fourth place on the all-time list for singles wins in the majors, behind only Roger Federer, who leads the way, Serena Williams and Djokovic.

Nadal of course leads the men's slam race with an unmatched 22 slams.

Berankis – 35/35

Naomi Osaka's shock withdrawal from the French Open generated an outpouring of support across the tennis world and beyond. 

The four-time grand slam winner pulled out of Roland Garros on Monday, a day after tournament organisers said her continued refusal to attend mandatory press conferences could result in her being thrown out of the event.

Osaka said in a statement posted to social media that she has had bouts of depression since winning the US Open in 2018 and never intended for her stance to become a distraction. 

Monday's action in Paris had mostly been completed when the news broke, but Serena Williams shared her thoughts following an evening match. 

Williams acknowledged feeling anxious dealing with the press at times early in her career, but said she believed the experience made her stronger. 

Top of mind, however, was concern for Osaka. 

"The only thing I feel is that I feel for Naomi. I feel like I wish I could give her a hug because I know what it's like," Williams said.

"We have different personalities, and people are different. Not everyone is the same. Everyone is different and everyone handles things differently.

"You just have to let her handle it the way she wants to, in the best way she thinks she can, and that's the only thing I can say. I think she's doing the best that she can."

Osaka's fellow players and others took to social media with encouraging messages for the 23-year-old. 

Venus Williams wrote on Instagram: "So proud of you. Take care of yourself and see you back winning soon!"

Young American star Coco Gauff responded to Osaka's tweet by writing "stay strong ... I admire your vulnerability." 

A pair of tennis legends also weighed in on Twitter. 

"I am so sad about Naomi Osaka. I truly hope she will be ok," Martina Navratilova wrote.

"As athletes we are taught to take care of our body, and perhaps the mental and emotional aspect gets short shrift.

"This is about more than doing or not doing a press conference. Good luck Naomi - we are all pulling for you!"

Billie Jean King added: "It’s incredibly brave that Naomi Osaka has revealed her truth about her struggle with depression. Right now, the important thing is that we give her the space and time she needs. We wish her well."

Mardy Fish, the former ATP player who reached number seven in the world, wrote to Osaka: "Mental health is nothing to criticise. Nothing to joke about. Pls [sic] take your mental health seriously. Without my support system, I truly believe I would not be here today. Here for you."

That public show of support extended beyond tennis, as prominent NFL and NBA players praised Osaka for her courage. 

"We are with you," said Seattle Seahawks quarterback Russell Wilson.

NBA star Stephen Curry wrote: "You shouldn't ever have to make a decison like this - but so damn impressive taking the high road when the powers that be don't protect their own. Major respect."
