The short answer
What US employment law does and does not protect during cancer: ADA accommodation, FMLA eligibility limits, EEOC filing deadlines, and the career harm that is real but not illegal.
The ADA covers cancer as a disability in four situations: while you have it, while in remission, as a record of past cancer, and where an employer merely regards you as having it. It applies to private employers with 15 or more employees and to state and local government.
There are no required words for requesting an accommodation, and the request can come from you, a relative or your doctor. Putting it in writing and dating it is for your protection, not the law's.
The EEOC filing deadline is 180 calendar days from the discriminatory act, extended to 300 days where a state or local agency enforces a comparable law. Federal employees must contact an agency EEO counsellor within 45 days.
You must file an EEOC charge before you can bring a job discrimination lawsuit under these laws, with the Equal Pay Act as the exception. Start at the EEOC Public Portal or call 1-800-669-4000.

The full explanation.
What the ADA actually gives you
The EEOC's position is unambiguous: cancer meets the ADA definition of disability. Someone currently being treated, and someone in remission, is substantially limited in the major life activity of normal cell growth. Someone with a history of cancer is covered under the "record of" prong. And someone an employer merely assumes has cancer is covered under "regarded as" — which is the prong that catches the manager who quietly decides you are no longer up to the travel.
Coverage applies to private employers with 15 or more employees and to state and local government; the Rehabilitation Act covers federal employment. Below 15, check your state or city fair employment law, which frequently has a lower threshold.
This is general information rather than legal advice. If your situation is serious, an employment lawyer or your state fair employment agency can apply it to your facts.
Requesting an accommodation
There are no magic words. The EEOC states plainly that a request can come from the employee, a family member or a health professional, in any wording. Common accommodations for cancer include leave for treatment and recovery, modified or part-time schedules, telework, additional breaks, a private space to rest, temperature adjustments, and reassigning or redistributing marginal tasks.
What makes a request work in practice:
- Write it down and date it. Email is fine. Keep a copy outside your work account.
- Lead with the limitation and the fix, not the diagnosis. "I need to work from home on Thursdays and Fridays for the next four months for a medical condition" is a valid request.
- Expect a documentation request. Employers may ask for medical support for the need. Your oncology team can write to functional limitations without disclosing everything.
- Know the confidentiality rule. Employers must keep medical information confidential and may not explain to colleagues why you are being accommodated.
- Get help free. The Job Accommodation Network, funded by the Department of Labor's Office of Disability Employment Policy, advises both employees and employers at (800) 526-7234.
An employer can refuse if the accommodation causes significant difficulty or expense, or if it would eliminate an essential function of the job.
Leave, and its narrow gate
FMLA provides 12 workweeks of unpaid, job-protected leave in a 12-month period, with health coverage continued and the right to return to the same or an equivalent job. It can be taken intermittently for treatment.
The eligibility limits matter more than the entitlement: 12 months with the employer, 1,250 hours of service in the preceding 12 months, and 50 or more employees within 75 miles of your worksite. Part-time workers, recent hires and small-employer staff frequently fail one of those tests. If you do, ADA leave as an accommodation, your employer's own policies, short-term disability insurance and any state paid leave programme are the remaining routes.
If something goes wrong, watch the clock
This is the part where delay does the most damage. The EEOC deadline is 180 calendar days from the day the discrimination took place, extended to 300 days where a state or local agency enforces a law prohibiting the same kind of discrimination. Weekends and holidays count, though a deadline falling on one rolls to the next business day. Federal employees operate on a different track and must contact an agency EEO counsellor within 45 days.
Filing a charge is a prerequisite to suing under these laws, apart from the Equal Pay Act. You can begin with an online inquiry through the EEOC Public Portal, or call 1-800-669-4000.
While you still have the job, keep contemporaneous notes: dates, who said what, what changed, and copies of performance reviews from before your diagnosis. Nobody enjoys doing this. It is the difference between a recollection and a record.
The harm the law does not reach
Some of what cancer does to a career is not discrimination. A promotion cycle you missed while on leave. A client relationship someone else now owns. A field that moved on in eight months. A reputation for reliability you feel you have to rebuild from zero. These losses are real and often permanent, and no filing fixes them.
Naming the difference is useful, because energy spent fighting an unwinnable characterisation is energy not spent on the accommodation that would actually make next month work. Outside the US, protections come from different statutes and different enforcement bodies with their own, often much shorter or much longer, deadlines — check your national equality or employment authority rather than assuming these rules travel.

Common questions
My employer has fewer than 15 employees. Am I unprotected?
Not necessarily. The federal ADA threshold is 15, but many states and cities have their own fair employment laws with lower thresholds, and some cover employers with a handful of staff. Your state fair employment practices agency is the place to check, and filing with them can also be what extends your EEOC window to 300 days.
Should I put my accommodation request in writing?
Yes. The law does not require it, but a dated written request creates a record of what you asked for and when, which matters enormously if things later go wrong. Describe the limitation and the adjustment you need rather than your full medical history, and keep a copy somewhere that is not your work email.
How long do I really have to file a complaint?
Shorter than most people assume, and the clock starts at the discriminatory act rather than when you feel able to deal with it. 180 days by default, 300 where a state or local agency enforces a comparable law, 45 days for federal employees to contact an EEO counsellor. If you are anywhere near a deadline, contact the EEOC first and work out the details after.
What if I just want the job to work, not a fight?
That is the usual and reasonable position. Start with the Job Accommodation Network at (800) 526-7234 — free, confidential, funded by the Department of Labor, and used by employers as often as employees. Most accommodation problems are solved by someone proposing a workable adjustment rather than by an enforcement process.
