Chelsea goalkeeper Ann-Katrin Berger announced Tuesday that her thyroid cancer has returned, spurring an outpouring of support from fellow players.

She first was diagnosed in 2017 while playing for Birmingham City, but she recovered within four months.

“Unfortunately, after four years of living cancer-free there has been a recurrence detected in my thyroid,” Berger wrote in a statement on social media. “I’ve said before that as a sportsperson you have to fight every day to be the best you can be and that’s something I will continue to do and I hope by sharing my journey, I can help others that find themselves in a similar situation.”

Berger said she is working with her club doctor and a London specialist. The goalkeeper is scheduled to begin cancer treatments next week and said she remains “positive” that the treatment will “be as effective as last time.”

“I’m looking forward to returning to the pitch and seeing you all at Kingsmeadow and Stamford Bridge,” she continued.

Berger is also a goalkeeper for the German national team. She recently made headlines when she and her girlfriend, England’s Jess Carter, played against one another in the Euro final.

U.S. women’s national team star and Olympique Lyonnais midfielder Lindsey Horan voiced her support for Berger. The two played together when Berger played for Paris Saint-Germain from 2014 to 2016. Horan was with the club from 2012 through 2016.

“We are all with you Ann,” she wrote. “Thinking of you my friend.”

Chelsea forward Sam Kerr, who joined the team in 2020, voiced her support as well.

“We are all with you,” she posted on Twitter.
