The bad news had arisen during a preparation course from Dortmund to Bad Ragaz in Switzerland.
Sébastien Haller had left his family because he had been diagnosed with a testicular tumor.
Recruited in the summer against 31 million euros, the largest amount committed by the German club for a striker, to replace the departure to Manchester City of Erling Haaland, the 28-year-old Franco-Ivorian striker will be absent "Several months" announced the German club, reassuring about the player's health situation: "He was successfully operated on last week.
He will definitely be away for a few months.
He is on the right track.
said BVB sporting director Sebastian Kehl.
Hello everyone, I wanted to let you know that Step 1 has been completed!
I would like to thank the @BVB and the medical team who have been exceptional with me.
A big thank you also to all the nursing staff of the hospital for their support - benevolence 🙏🏽💪🏾 # step1 pic.twitter.com/jr1G7ILYZI

But even if Sébastien Haller is doing well, their striker's absence from the field for the first part of the season could cause problems for Dortmund.
The only top striker currently in Bayern's runner-up squad is the young but promising 17-year-old Youssoufa Moukoko.
If coach Edin Terzic has indicated that Donyell Malen, Karim Adeyemi or even Thorgan Hazard can also play at the top, the club could be active on the transfer market before the start of the season.
The name of Marseillais Arkadiusz Milik is circulating but no concrete offer has arrived in Marseille.
The sporting director of the German club said in this regard "we will only do something if it makes sense in the end".
Dortmund will play their first official game of the season on Friday against 1860 Munich, a club in the German 3rd division, in the Cup.
The resumption of the Bundesliga will take place on the weekend of August 6, BVB will host Leverkusen on the first day.
