Dear Diagnosis is a weekly letter by me, Lea, 32, navigating breast cancer — and writing about all of it.
In this issue: two days before her mastectomy, I sat alone in the hospital waiting room. A stranger sat down next to me. What he said, and what I allowed herself to feel, is something I have thought about ever since. If you're new here, start with Issue #001 — the scan that started everything.
ISSUE #006 · June, 21st 2026
The man in the waiting room.
On strangers, kindness, and the things we allow ourselves to feel in front of people we'll never see again.
On 12 August — two days before the operation — I went to see Dr. Martin alone. She was going to walk me through the results of all the tests.
Dr. Martin runs late. She often has to leave mid-appointment to cover emergency surgeries. Last time I waited three hours to see her. This time I came prepared: a book, no expectations.
There was no network in that waiting room. Several people sat around me, all of us quiet, all of us there for the same doctor. At some point, a man started asking everyone what time their appointment was. Trying to work out how late she was running.
| The stranger with the same appointment: what happens when you're alone in a cancer waiting room
It turned out he and I had been given the same slot. Probably because mine had been added at the last minute — Dr. Martin had squeezed me in.
When he noticed I was alone, he paused. He asked me why I was there. I could feel that his question came from pure curiosity and something else — a kind of quiet sadness, as though he already suspected the answer and was hoping he was wrong.
I told him I had breast cancer and that I was going to have surgery in two days. I said it calmly. The way I always did — dissociating the disease from myself, as if I were describing something that was happening to someone nearby rather than inside my own body.
He sat down next to me. He asked if I was okay. His kindness was so direct and so genuine that it made me cry.
It was the first time I cried in front of someone other than my husband about my cancer. And I'd allowed myself to, precisely because it wouldn't hurt him the way it would hurt someone close to me.
He told me he was there for his mother — that Dr. Martin would be operating on her too. He shared that he was frightened. Cancer had taken over his family: his wife had brain cancer, and now this with his mother.
We talked for a long time. Our conversation felt real in a way that conversations with people who know you sometimes can't — there was nothing to protect, nothing to manage. He opened up to me as though he'd decided, on instinct, that I was someone he could trust. That moved me.
| The book a stranger recommended — and what a woman cycling across France gave back to me
At some point he mentioned a woman he knew who had also had breast cancer young — roughly my age. She had written a book about it. I wrote down the name: Le jour où j'ai rencontré un crabe. He said she was now cycling across France.
I didn't order the book right away. At that point, I felt I was managing. I didn't think I needed it.
But I did look at her Instagram. There she was — her and her family, crossing the country on bikes, looking strong and happy and fully alive. As if to say: you come through this, and then you really live.
It gave me something back. Sport had always been my anchor — the thing that made me feel capable, at home in my body. I had stopped when I came back to France. Too busy, no routine yet. Seeing her out there on that road made me want to find my way back to it.
| What strangers gave me during my breast cancer journey that people close to me couldn't
We said goodbye and wished each other luck. When he came out of his appointment with Dr. Martin, he looked a little lighter. He told me he was relieved — that his mother was in good hands.
Then I was called in.
I thought about him afterwards. I still do. Throughout everything I went through, the people who surprised me most were the ones I had no reason to expect anything from. Strangers — in waiting rooms, at radiologist's desks, in hospital corridors — who saw me, and who gave me something without being asked.
He felt like a sign, an angel sent to me. Not in a grand sense. Just in the quiet sense that sometimes the right person appears at the right moment, and all they have to say is: it's going to be okay.
I believe them when they're strangers. There's nothing at stake in their kindness. That's what makes it feel true.
To be continued next Sunday.

What happens in Issue #006?
Two days before my mastectomy, I went to the hospital alone for a results consultation. Dr. Martin was running late — she always does. In the waiting room, I ended up talking to a man who was there for his mother. He asked if I was okay. Something about the way he said it made me cry. It was the first time I'd cried in front of anyone but my husband about my cancer. I've thought about him a lot since. This issue is about that conversation — and about what strangers can give you that the people close to you sometimes can't.
