Sarah Kuttner starts chemotherapy and will document it in a YouTube video diary

Video diary and the start of treatment

Sarah Kuttner, a 47-year-old presenter and author based in Berlin, has announced that she will accompany her chemotherapy with a video diary. In an Instagram video shared on 10 November 2026, she said that the day was the last before her treatment began. She described herself as tense and said she had decided to keep a vlog on her YouTube channel about the process. Kuttner was unsure whether she would follow it through, pointing to her ADHD and to plans she makes that do not happen. She wants to post regular updates for people who share her fear, and said she had enjoyed watching similar videos herself.

“Today is the last day before my chemo.”

She also posted two photos, one showing a brown-haired wig in a box and one showing scissors, combs and hair clips. She wrote that she had the salon open and would cut her "new old hairstyle" herself, and said she would film the process and publish it online soon. Many followers wished her love, strength and confidence, and some shared their own chemotherapy experiences in the comments.

Diagnosis and treatment plan

Kuttner made the diagnosis public at the end of September in a video, after a visit to her gynaecologist for cancer screening. She had originally expected to manage with antihormone therapy and an operation. An Oncotest then showed that a threshold relevant to the treatment decision had been exceeded, though only narrowly, and she disclosed this in early November on her podcast Das kleine Fernsehballett, which she runs with the journalist Stefan Niggemeier. In mid-October she had told the podcast that the cancer sat in her right breast and measured three centimetres.

“My tumour is a bit bumpier than people thought.”

The chemotherapy is planned to run for four and a half months, with surgery to follow. She described the therapy as one with a real punch, using the word "Wumms", and said she would have no hair left by Christmas Eve. Her appointments fall on Wednesdays, the same day new podcast episodes are released.

Cancelled appearances and podcast plans

Part of the podcast's stage tour planned for spring 2027 has been cancelled, and Kuttner also cancelled planned readings from her novel Mama & Sam. She said she intends to continue the podcast with Stefan Niggemeier. The cancellations were announced in the same period as her treatment plans, which she has discussed publicly in her podcast and on social media.

Timeline so far

The public sequence runs from the diagnosis video in late September 2026 to the expected loss of her hair by Christmas Eve.
