Delani Diekmeier Speaks Out on Cancer Battle After Treatment Setback

“Man muss sich nicht einschließen. Es wird nichts besser, wenn du nur auf dem Sofa liegst und weinst,” said Delani Diekmeier, Bild reported.

“Es ändert nichts an der Tatsache,” said Delani Diekmeier, Bild reported.

Delani Diekmeier spoke publicly about her cancer diagnosis for the first time in Hamburg, joined by her mother Dana Diekmeier, according to Bild. The 15-year-old daughter of former HSV professional Dennis Diekmeier faced a therapeutic setback after a laboratory test involving lung metastasis tissue and a new medication showed the cells only responded by a third, Bild reported.

The low prospect of success ruled out the treatment, alongside the threat of severe side effects and an extended hospital stay, leading the family to decide against the therapy for the time being, according to Bild. Dana Diekmeier told Bild that the news initially disappointed Delani, who remains positively minded and enjoys life.

Doctors first discovered an aggressive tumor on Delani’s adrenal gland in early 2025, which surgeons removed before metastases formed in the lungs, Bild reported. Despite immunotherapy, the metastases continued to grow, as her mother made public in July, according to Bild.

The teenager plans to spend December working at a charity event for homeless people in Hamburg. Dana Diekmeier told Bild that the idea came directly from her daughter.

“Es war ihr Herzenswunsch. Ich war eingeladen und Delani hat gefragt, ob sie da mitkann. Ich bin so stolz auf meine Tochter,” said Dana Diekmeier, Bild reported.

The mother and daughter spent days away from medical clinics in their former hometown to focus on time together. Wir haben hier einfach eine gute Zeit.” No further cancer treatments are scheduled to begin this year.

Delani turns 16 on December 18, with the family planning a large party now that hospital visits for a new therapy are paused for the remainder of the year, Bild reported. Dana Diekmeier told Bild about the celebration, stating, “Wir machen natürlich eine große Party. Additional plans include Christmas shopping in London and competing in a major equestrian tournament in Leipzig in January, according to Bild.”
