A cancer diagnosis can affect many aspects of your life, including your work. You may be wondering whether you can continue working during treatment, when you can return to work, or how your diagnosis might affect your career and finances.
There is no single “right” decision. Some people continue working throughout treatment, while others need to reduce their hours or take time away from work. The best approach depends on your health, the type of work you do, your treatment plan and your personal circumstances.
How cancer may affect your working life
Cancer and its treatment can affect work in different ways.
Physically
Treatment side effects such as fatigue, pain, nausea or difficulty concentrating may affect your energy levels and productivity. Some treatments may also weaken your immune system, making you more vulnerable to infections.
Emotionally
A cancer diagnosis can bring feelings of anxiety, uncertainty and stress. These emotions may make it harder to focus, make decisions or manage the demands of work.
Practically
You may need time away from work for appointments, treatment or recovery. Some people also find that they need temporary adjustments to their workload or working hours.
Financially
Taking time away from work may affect your income, particularly if you require extended leave or unpaid leave. If you are worried about your finances, support may be available.
Deciding whether to continue working
Whether you continue working during treatment is a personal decision. Some questions to consider include:
- How is treatment affecting my physical and emotional wellbeing?
- Is my work physically demanding or high stress?
- Can my employer offer flexible work arrangements?
- Is it safe for me and others if I continue working?
- What financial support is available if I need to take leave?
- What advice has my healthcare team given me?
Discuss your situation with your healthcare team before making major decisions about work. They can advise whether any adjustments may be helpful during treatment.
Talking to your employer
You are not required to share every detail of your diagnosis. However, if your condition could affect workplace safety or your ability to perform your role, it is important to have an open conversation with your employer.
When discussing your situation, you may wish to focus on:
- How treatment may affect your work.
- Temporary adjustments that could help you continue working.
- Time off for treatment or recovery.
- Your expected communication arrangements while on leave.
Many employers are willing to explore flexible work arrangements such as:
- Flexible working hours
- Working from home where appropriate
- Temporary changes to your workload
- Adjusted duties
- Phased return to work after treatment
Returning to work after treatment
Returning to work can be both exciting and challenging. Some people return to the same role, while others decide to change jobs or adjust their working arrangements.
As you prepare to return to work, consider:
- What tasks you feel comfortable performing.
- Whether you need temporary workplace adjustments.
- Whether you require additional training or support.
- How you will manage fatigue or other ongoing side effects.
Take things at a pace that works for you, as recovery looks different for everyone.
Your employment rights
If you need time off for treatment, speak with your employer or Human Resources department about your leave entitlements.
Employees covered under Singapore’s Employment Act may be entitled to paid outpatient and hospitalisation sick leave if they meet the eligibility requirements.
Employers in Singapore are also expected to comply with the Tripartite Guidelines on Fair Employment Practices. If you believe you have been treated unfairly at work because of your cancer diagnosis, you may seek advice from the Tripartite Alliance for Fair and Progressive Employment Practices (TAFEP).
Managing relationships at work
Deciding whether to tell your colleagues about your diagnosis is a personal choice. Some people prefer to keep their diagnosis private, while others appreciate the understanding and practical support of trusted colleagues.
If you decide to share your diagnosis but feel uncomfortable having those conversations yourself, you may wish to ask your manager or Human Resources representative to communicate the information on your behalf.
Remember that your medical information should only be shared with others with your consent.
Looking after yourself at work
Balancing work and treatment can be demanding. However, looking after your well-being is just as important as meeting work responsibilities.
You may find it helpful to:
- Keep track of appointments, leave and work commitments.
- Prioritise important tasks.
- Accept help from colleagues where appropriate.
- Take regular breaks during the workday.
- Be realistic about what you can manage.
- Speak up early if you need additional support.
Support beyond the workplace
Managing work during cancer can sometimes feel overwhelming, especially if you are balancing treatment, finances and family responsibilities.
