Returning to Work After Cancer, Part 1: How to Decide What Stays, What Shifts, and What Goes

March 08, 20266 min read

You already know this, but you might need to hear it anyway:

Going back to work after cancer isn’t just about showing up again.

It’s about figuring out what “work” even is for you now.

Because cancer doesn’t just drain your energy. It rearranges your priorities. It changes your tolerance for stress. It changes what feels meaningful… and what feels like a complete waste of your one wild life.

So if you’re standing at the edge of “returning,” feeling uncertain and overwhelmed, you’re not doing it wrong. You’re doing the recalibration.

This is Part 1 of a two-part series on returning to work after cancer. This week we’re zooming out—what ‘work’ is now, and how to decide what stays, shifts, or goes. Next week, in Part 2 we’ll get into the scripts, requests, and boundaries that protect your energy and privacy.

Here are a couple of issues that tend to show up right away.

One is the obvious one: Can I physically and mentally do what I used to do? Sometimes the answer is yes. Sometimes it’s yes-but-not-all-at-once. And sometimes it’s no—not because you’re weak, but because your body (or brain) has new limits you didn’t ask for.

The other issue is sneakier: Even if I can do it… do I want to anymore?

For some people, cancer turns the volume up on the parts of work they actually enjoy. For others, it exposes how much of their job they’ve been tolerating, white-knuckling, or doing purely out of obligation. And suddenly those parts feel… unbearable.

This is why “returning to work” can’t be one single decision. It has to be a series of smaller ones.

Because most jobs aren’t one job.

Some roles are pretty singular—same basic work, all day long. But many careers are more like a bundle of different jobs stacked on top of each other. There’s the core work. The administrative work. The meetings. The leadership piece. The teaching or mentoring. The crisis management. The emotional labor. The extra “invisible” tasks that somehow became yours.

And when you try to pick up all of it at once after cancer, it can feel like someone asked you to sprint… with a backpack full of bricks.

So here’s a high-level approach I use with clients that’s simple, but surprisingly powerful:

Make a list of the major “buckets” of your work.

Then, for each bucket, ask two questions:

  • How does this part of my job make me feel now—physically and emotionally?

  • If I had limited energy (because I do), is this how I want to spend it?

Notice I didn’t ask, “What do other people expect?” or “What should I do?” or “What will they think?” Those questions will hijack your nervous system every time.

Instead, we’re aiming for data. Your body’s feedback. Your values. Your lived experience.

Because you might discover that one piece of your work still lights you up. It gives you energy. It reminds you who you are. And another piece—one you used to tolerate—now feels like sandpaper on your brain.

Don’t blow past that.

It doesn’t mean you have to blow up your career tomorrow. Sometimes you can’t change things right away. Sometimes you need the paycheck, the benefits, the stability, the routine. That’s reality.

And this is also where the decision-making part can get tricky—because you’re not just choosing based on what you “like.” You’re choosing based on capacity.

When you’re sorting through what stays, what goes, and what changes, you’re usually juggling three things at once:

  • Physical energy (stamina, pain, sleep, appointments, recovery time)

  • Mental and emotional bandwidth (focus, decision fatigue, anxiety, grief, overwhelm)

  • Interest and meaning (what lights you up now… and what you can’t tolerate anymore)

Sometimes the “right” answer is obvious. And sometimes it isn’t. Sometimes you’re considering something new—a new role, a new track, a new project—and you can’t possibly know how it will feel until you’re living it.

So you make the best guess you can. You choose what you think you’ll love the most (or what will drain you the least). And then you give yourself permission to adjust.

Because for most people, there’s no urgency. You can settle back into work, gather data, notice what feels doable, and make changes as you go. In fact, that’s often the smartest path—especially when your energy is still unpredictable.

But sometimes there is urgency. Maybe you’re being offered a new position—and if you don’t say yes now, it goes to someone else. Maybe your workplace needs an answer. Maybe the window is real.

If you’re in that situation, here’s what tends to work well:

If taking the new role matters to you (or it’s part of where you’re headed), consider taking it—and then protect your energy by cutting back on the parts of your current job that are easiest to add back later.

For example: if you’re stepping into an administrative or leadership role, you might temporarily reduce the more easily scalable parts of your work—like the amount of time you spend with clients or patients, the number of classes you teach, or other responsibilities you can ramp back up when your bandwidth improves. It’s often easier to add those pieces back later than it is to step away from a role you’ve already said yes to.

And remember: very few decisions in life are truly irrevocable. If you later realize you made the wrong call, it doesn’t mean you’re stuck. It means you pivot. You renegotiate. You rebalance. You course-correct.

That’s not failure. That’s responding to new information.

In other words: you don’t have to get it perfect. You just have to get it moving in a direction that supports your life.

But even if you can’t change everything today, you can start paying attention. You can start experimenting. You can start adjusting the ratio.

More of what lights you up. Less of what drains you.

And if you’re already wondering, “Is my job slowly killing me?” — you’re not alone. I previously wrote about that here: You Survived Cancer—But Is Your Job Slowly Killing You?

One more thing: if you were being considered for a new role before treatment, or if your job is shifting while you’ve been out, that can add another layer of pressure. It’s easy to feel like you have to prove you’re still capable, still committed, still you.

But “still you” isn’t the point.

The point is: you get to decide what you’re returning to.

And you don’t have to decide it all at once.

Next week, in Part 2, we’ll get very practical: what to do and say when you’re easing back in, how to protect your energy, how much to share (or not share), and what to request so you can do your job without burning out.

Because the big picture matters. And the day-to-day words matter too.

If you’re trying to sort through what stays, what goes, and what gets rebuilt—and you feel frozen—let’s talk. We can map the “buckets,” find what actually works for your body now, and build a return plan that doesn’t require you to sacrifice yourself to your job.

You’ve already been through enough.
