There's a particular silence I learned to recognize in oncology. It would come after the hard conversation, the staging, the plan, the questions answered, when a patient would look out the window and say, almost to themselves, "I wish I'd known sooner." Not as blame. Just as a quiet ache for a different version of the story.
I spent the early part of my career caring for breast cancer patients at the University of Miami, and that work shaped me in ways I'm still unpacking. It will always be part of who I am as a clinician. It's also a big part of why I do what I do now, which on the surface couldn't look more different.
In oncology, you meet people at one of the hardest moments of their lives, and you learn things you can't unlearn. You learn what the body can endure, which is staggering. You learn how much skilled, attentive, human care matters when someone is frightened and stripped of their usual sense of control. You learn that health, real health, has almost nothing to do with a number and everything to do with whether someone can get through their day with energy and dignity. And you learn, from that window and that ache, how often people longed for a chance to have acted earlier, while there was still room to change course.
I want to be careful here, because this is delicate ground. A lot of illness isn't anyone's fault. Life is complicated, bodies are mysterious, and "you should have caught it sooner" is a cruel thing to lay on anyone, and not what I'm saying. What I am saying is that those years left me thinking constantly about a stretch of time that gets almost no attention: the long, quiet window before a crisis. The years where metabolic health slowly drifts, energy fades a little at a time, risk accumulates in the background, and everything still seems basically fine on the surface. Nobody's scared yet. Nothing's urgent. And that, it turns out, is exactly where an enormous amount of the meaningful work in health actually lives, and exactly where the least attention gets paid.
That window is where I wanted to spend more of my time. So I moved toward this work, weight management, metabolic health, helping people feel genuinely well rather than merely not-yet-sick. It's a strange pivot on paper, from the most acute end of medicine to the most preventive. But to me they're two ends of the same thread. Oncology is the late chapter. This is the early one. And after years of meeting people in the late chapter, I found I wanted to spend more of my days in the early one, where there's more road left to change.
It's less dramatic, I'll grant that. No one writes movies about helping a guy bring his blood sugar down before it becomes a diagnosis, or talking a tired woman through the labs that explain why she's exhausted, or simply being the clinician who finally slows down and connects the dots. There are no monitors beeping, no high-stakes scenes. It's undramatic on purpose. But after sitting with enough people who wished for a sooner that never came, undramatic and early started to feel like the most important place I could be.
I'm not naive about it. Prevention isn't a guarantee against anything; you can do everything right and still get unlucky, and I learned that lesson in the hardest possible classroom. I don't promise patients that taking care of themselves now will keep every bad thing away, because that would be a lie, and they deserve better than comforting lies. What I can offer is the chance to help someone change direction while they still have plenty of road ahead, to use the early window well instead of arriving at the late one wishing they'd started.
That's the whole reason I do this. Not because the early work is glamorous. Because I've sat in too many rooms at the other end, listening to that quiet "I wish I'd known sooner," and I'd rather spend my career on the side of the story where sooner is still possible.
