Piotr is a man with his heart on his sleeve, who has a good sense of humor and incredible courage.
A loyal fan of soccer and the Lech Poznań team.

A boxing enthusiast who has been closely involved with Poznań boxers and the combat sports community for many years. He has organized galas and supported fighters in the corner. Always helpful!

Husband and father of two teenagers.

After his 40th birthday, he did something that many people put off for years: he quit smoking after 25 years. He didn't drink alcohol, exercised regularly, and ate healthily.
In mid-January 2026, a few episodes of headache did not cause much concern. After all, it happens to everyone. Two weeks later, he developed paresis of the arm. Physiotherapy did not bring any improvement, and the left side of his body gradually lost strength.

On February 12, Piotr was admitted to the emergency room of the University Clinical Hospital in Poznań with suspected stroke. The next day, Friday, February 13, 2026, we heard the diagnosis: brain tumor.
Round 1: brain tumor surgery.

On February 18, a craniotomy was performed to remove the lesion. Further treatment will depend on the results of histopathological tests.
The diagnosis is glioblastoma multiforme (grade IV). A fast and aggressive opponent.

The operation was successful, and the player is now heading to the corner to catch his breath. The corner is strong, filled with loving family and friends.

On Peter's leg is an image of Muhammad Ali with the inscription:
"I am the greatest. I said that even before I knew I was."
It's not decoration. It's a declaration.

The player advances to the second round, and the name of this round will be announced in early March. We can expect chemotherapy, radiotherapy, and all available methods that can realistically support the fight, including those that are not reimbursed.

Piotr treats illness as an opponent that must be understood, whose blows must be endured and responded to with his own. He wants to be a source of motivation for others who are facing illness, doubt, and fear.

This story is about a man who, at the most difficult moment of his life, goes into battle with his head held high and does not throw in the towel.

Let's go, champ!

Round 2. More information will be available in early March.
