Having large breasts can cause women to have back ache, neck pain and poor posture - and according to a recent reports, it can also really affect their tennis performance.
Romanian tennis star, Simona Halep, is now ranked third in the world and it's all down to her breast reduction, apparently.
“It’s the weight that troubles me. My ability to react quickly, my breasts make me uncomfortable when I play," Simona said, at the time of the operation, according to NY Post.
"I don't like them in my everyday life. I would have undergone surgery if I hadn't been a sportswoman."
The 22-year-old's coach, Wim Fissette, recently said that surgery was the "right decision" for Simona, who had her 34DD breasts reduced to a 34C aged 17.

According to The Independent, Wim said: "It has been an important part of her career.
“I guess it was the right decision. I did not see her then. I have seen some photos, but she took that decision and it was a good one. I understand that.
"That’s why she was famous [because of her large breasts]. Let’s hope she will win a Grand Slam and then they will start talking about the Grand Slams and not something else.”
Wim announced that he would begin coaching Simona in January this year.
Speaking about her technique, he said: “She is fast, she moves very lightly on the court, she always has very good balance and she makes very smart choices on the court.”
He added: "She is very intelligent on court. When things are not going right, she is trying to find a solution by herself. Especially on changeovers you see her thinking.”
Since the surgery, Simona has overtaken former champion Maria Sharapova, reached the fourth round at last year’s US Open, reached the quarterfinals at the Australian Open in January, and made it to the French Open final a few weeks ago.
A recent study found nearly one in five women said their breasts stopped them participating in physical activity, although being unable to find the right sports bra, regardless of size, was the main factor.
