Nicolas Mayer‑Rossignol reports the recurrence of his bladder cancer and assures that he will continue to carry out his duties.

Rouen – 30 June 2026: Rouen Mayor Nicolas Mayer‑Rossignol (Socialist Party) has made public the news that he has been diagnosed with a recurrence of bladder cancer. In a statement published on 29 June, Mayer‑Rossignol said that he had already undergone another surgical procedure and was in stable condition. He promised to continue carrying out his duties and to provide transparent updates on his health.

According to the statement, the most recent surgery took place on 9 June; the mayor was discharged from hospital on 13 June. According to local media and the Rouen city administration, suspicious findings had emerged at the end of April, leading to further examinations. In his statement, Mayer‑Rossignol referred to the recurring nature of the illness: the first diagnosis dates back to 2022, and several procedures and treatments have followed since then.

The 41-year-old politician had already made the diagnosis public in 2024; at the time, he explained that he had been receiving treatment for bladder cancer since 2022. His new diagnosis comes at a time when he remains politically active: Mayer‑Rossignol was confirmed in his post by the city council in March 2026 and has led the municipal majority since then. In his statement, he stressed that he would continue to fulfil his responsibilities as an elected representative.

From a medical perspective, repeated check-ups, procedures and sometimes complementary therapies are common for superficial bladder cancer; the course of the disease can be marked by recurrences. In his statement, Mayer‑Rossignol announced further examinations planned for October to assess the risk of progression and determine subsequent management. He thanked his family and medical staff for their support.

Politically, the news was received pragmatically in Rouen and the Métropole Rouen‑Normandie: both municipal offices and local media reported on the mayor’s statement and highlighted his assurance that he would not neglect official business. The city administration also confirmed routine procedures and delegation rules for short-term absences.

The statement follows several months during which Mayer‑Rossignol has remained politically present, most recently through initiatives related to the municipal agenda and public events. Observers stress that in France, open communication about health issues is increasingly expected when they may affect the ability of elected officeholders to act.

For citizens and political partners, it remains essential that medical information be communicated accurately and promptly; Mayer‑Rossignol assured transparency and announced that he would keep them informed about further findings and decisions.
