Do you have to tell a new employer about your cancer history?

People do not usually worry about disclosure because they want to keep a secret. They worry because they expect the truth to cost them the job.

The law's answer is structured around timing. What an employer may ask depends entirely on which stage of hiring you are in.

At this stage the door is closed. Employers cannot ask applicants about cancer history or treatment.

What they can do is ask job-related questions. The EEOC's illustration is a question like whether you can lift 50 pounds. That is about the work, not about you.

And your obligation? You are not required to disclose cancer, with one narrow exception: if you need an accommodation for the application process itself. Someone who needs an accessible interview location or a modified testing arrangement would raise that.

Silence about your health during an interview is not dishonesty. It is the arrangement the law sets up.

The rules change once an offer is on the table. At that point, employers may ask detailed health questions and require medical examinations.

Two guardrails apply. Everyone entering that job must be treated the same way, so this cannot be a screen aimed at one candidate. And the follow-up questions center on your treatments and whether you can safely perform the job's functions.

The purpose of this stage is not to relitigate whether you deserve the job. It is to determine what, if anything, is needed for you to do it.

Employers do not get open-ended access to your medical life just because you are on the payroll.

Medical questions during employment are limited to two situations. One is where the employer has observed performance problems and reasonably believes a medical condition is causing them. The other is where there is objective evidence of a safety concern.

Curiosity is not on that list. Neither is a rumor.

Plenty of survivors choose to disclose, and there are real reasons to:

• You expect to need scheduled time off for follow-up scans
• You will need an accommodation from the start
• You would rather not manage the topic as a secret
• The role involves demands you know you should discuss

There are also real reasons not to, and the point of the rules is that either choice is yours to make. If you do decide to disclose, the practical advantage of waiting until after an offer is that the employer has already decided they want you.

If a pre-offer application form asks about your medical history, or an interviewer probes your health, that is not how the process is supposed to run. Write down what was asked and by whom.

The EEOC handles complaints about disability discrimination in hiring. Contacting them to ask a question is not the same as launching a case.

Interviews are hard enough without carrying a fear that one honest sentence will end things. Prepare for the questions the job actually permits: what you can do, what you have done, what you would bring. Your medical history is not the interview's business, and you can enter the room knowing that.

Some people are asked about employment gaps, which is a legitimate question about work history rather than health. You can answer it without discussing your medical life.

A short, calm sentence about having taken time away for personal or health reasons, followed by what you have been doing to prepare for returning, is usually enough. Practise it once so it comes out steadily.

If you later need adjustments, the accommodation process is available to you as an employee. Nothing about having stayed quiet during interviews takes that away.

That is worth knowing in advance, because it means the interview does not have to carry every decision at once.
