Telling Your Employer About Your Breast Cancer Diagnosis
This is a deeply personal decision, and there's no single "right" answer. Let me walk you through the key considerations and your legal protections.
Your Legal Rights
You have important protections under U.S. law. According to the Americans with Disabilities Act (ADA), people diagnosed with cancer have specific rights regarding:
- Keeping your diagnosis confidential - You can choose not to disclose
- Work accommodations - You can request schedule changes or periodic breaks for treatment
- Job protection - Your employer cannot legally discriminate against you based on your cancer diagnosis
The U.S. Equal Employment Opportunity Commission (EEOC) publishes specific guidance on cancer in the workplace that your employer should follow.
Practical Reasons You Might Tell Your Employer
Treatment will likely affect your work:
- Doctor appointments (often frequent during diagnosis and treatment)
- Potential side effects that impact your ability to work (fatigue, concentration, physical limitations)
- Possible need for time off for surgery, chemotherapy, or radiation
- Unpredictable health changes
Benefits of disclosure:
- Your employer can legally adjust your schedule to accommodate treatment
- Reduces stress from hiding your situation
- Allows coworkers to understand changes in your performance or availability
- May qualify you for FMLA (Family and Medical Leave Act) protections if your company has 50+ employees
Practical Reasons You Might Not Tell
- Privacy concerns
- Fear of workplace discrimination (despite legal protections)
- Concern about how colleagues will treat you
- Worry about job security or advancement opportunities
- Your treatment may have minimal impact on work
If You Decide to Tell
What to communicate:
- Keep it factual and brief - you don't owe detailed medical information
- Focus on what you need: "I'll need flexibility for medical appointments" rather than extensive health details
- Mention your timeline: "I expect treatment to last approximately [timeframe]"
- Discuss specific accommodations needed
Who to tell:
- Your direct supervisor and HR department (they're legally required to keep medical information confidential)
- You can choose whether to tell coworkers
Questions to Ask Your Healthcare Team
These will help you plan your work situation:
- "What is my expected treatment timeline, and how much time will I need off work?"
- "What side effects should I expect, and how might they affect my ability to work?"
- "Can I work during treatment, or will I need to take leave?"
- "Are there specific work restrictions I should follow during treatment?"
- "How frequently will I need medical appointments?"
Additional Resources
The Musella Foundation's guidance emphasizes that many people can work during cancer treatment following surgery and radiation, provided their work schedule allows for doctor visits and they can manage treatment side effects. However, this varies greatly depending on:
- Your specific treatment plan
- Your job type and flexibility
- How your body responds to treatment
- Your employer's willingness to accommodate
Key Takeaway
You have legal protections either way. The decision should be based on:
- How much your treatment will realistically affect your work
- Your comfort level with disclosure
- Your employer's track record with employee health issues
- Your need for workplace accommodations
Many patients find that some level of disclosure helps reduce stress and allows them to focus on treatment rather than hiding their situation.
