The short answer
What US employment law does and does not protect during cancer: ADA accommodation, FMLA eligibility limits, complaint deadlines, and the career harm that is real but not illegal.
ACS says the ADA recognizes cancer-related disability and applies to employers with 15 or more employees, including state and local government.
Putting an accommodation request in writing and dating it creates a record. Describe the limitation and the change you need.
You generally have 180 calendar days from the discriminatory act to file a charge with the EEOC, or 300 days if a state or local agency also enforces a law against that discrimination. Contact the EEOC at 1-800-669-4000 promptly rather than waiting.
FMLA gives eligible workers up to 12 weeks of unpaid leave a year. You need 12 months with the employer, 1,250 hours worked in the past 12 months, and a worksite with 50 or more employees within 75 miles.

The whole article, with every detail and caution.
This page is for working people with cancer in the US. It covers your rights under the Americans with Disabilities Act (ADA), how to ask for changes at work, unpaid leave, and the deadlines that apply if you face discrimination.
What the ADA gives you
ACS says the ADA recognizes cancer-related disability, because cancer and its treatment can affect many body functions. The law applies to employers with 15 or more employees. That includes private employers, state and local governments, employment agencies and labor unions. Below 15 employees, check your state or city law.
This is general information rather than legal advice. An employment lawyer or your state fair employment agency can apply it to your facts.
Requesting an accommodation
ACS gives these examples of accommodations: equipment or devices, changed work schedules, revised training materials or policies, and a workplace that is easy to get into and use. Employers do not have to provide changes that would be excessively costly or difficult.
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. For example: "I need to work from home on Thursdays and Fridays for the next four months for a medical condition."
- Expect a documentation request. Ask your oncology team to describe functional limitations without listing every detail.
Leave, and its narrow gate
ACS says FMLA lets eligible employees take up to 12 weeks of unpaid leave per year for a serious health condition, including your own cancer treatment or caring for a family member.
You need all three:
- At least 12 months with the employer.
- At least 1,250 hours worked in the past 12 months.
- A worksite with 50 or more employees within 75 miles.
Part-time workers, recent hires and small-employer staff often fail one of those tests. If you do, ask about your employer's own leave policies, short-term disability insurance, and any state paid leave program.
If something goes wrong, act quickly
The EEOC says a charge must be filed within 180 calendar days of the discrimination. That limit is extended to 300 days if a state or local agency enforces a law against the same kind of discrimination (for age discrimination, only a state law extends it). Do not wait until you feel ready. Contact the EEOC at 1-800-669-4000 as soon as you suspect discrimination, and ask which deadline applies to you. Source: EEOC time limits for filing a charge.
While you still have the job, keep notes. Record dates, who said what, and what changed. Keep copies of performance reviews from before your diagnosis.
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. Energy spent fighting an unwinnable characterization is energy not spent on the accommodation that would actually make next month work.
Outside the US, protections come from different laws and agencies. 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 employees, but some states and cities have their own laws. Your state fair employment agency can tell you what applies.
Should I put my accommodation request in writing?
Yes. A dated written request creates a record of what you asked for and when. 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?
The EEOC says you need to file within 180 calendar days of the discrimination. The limit is extended to 300 days if a state or local agency enforces a law against the same kind of discrimination. For age discrimination, only a state law extends it. Contact the EEOC at 1-800-669-4000 as soon as you suspect discrimination and ask which deadline applies to you (EEOC).
What if I just want the job to work, not a fight?
That is a reasonable goal. Start by asking your employer, in writing, for a specific change such as a schedule adjustment. Your care team's social worker can help with the paperwork.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education. Low-risk educational or organizational content. Medical facts are cited to authoritative sources.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
