A breast cancer diagnosis brings enough to think about without worrying whether you can keep your job, take time off for treatment, or arrange a holiday. The good news is that UK law gives you real protection at work, and there are clear, practical steps you can take around sick pay and insurance. This guide explains your rights in plain English so you can focus on your health and your treatment.
This is general information to help you understand your options. It is not legal advice or personal medical advice. For decisions about your treatment and how it may affect work, speak to your GP, breast care nurse or treatment team. For employment or money questions, your local Citizens Advice and the charities listed below can give free, confidential support.
You are protected from the day you are diagnosed
According to Cancer Research UK, the Equality Act 2010 means that anyone with cancer is treated as a disabled person under the law. This protection starts from the time you are diagnosed, and you do not have to have symptoms to be covered. It continues even after treatment finishes and there is no longer any sign of the cancer.
The Equality Act 2010 covers England, Scotland and Wales. In Northern Ireland, similar protection comes from the Disability Discrimination Act. Cancer Research UK explains that the protection works in much the same way across the UK: your diagnosis should not be used to treat you unfairly.
Being covered by the law means an employer must not treat you worse than other staff because of your cancer. This is called discrimination, and it is against the law. The protection applies to recruitment, pay, promotion, training, dismissal and redundancy. It also covers harassment and being treated unfairly because you have asked for support.
Reasonable adjustments at work
Because cancer counts as a disability, your employer has a legal duty to make what the law calls reasonable adjustments. These are sensible changes that help you stay in work or return to work during and after treatment. According to Cancer Research UK, examples of reasonable adjustments can include:
- Time off to attend hospital appointments, chemotherapy or radiotherapy
- Flexible or reduced hours while you recover, then a gradual build-up of your workload
- A phased return to work after time away, sometimes starting with shorter days
- Working from home where your job allows it
- Lighter duties, extra rest breaks, or moving a desk closer to facilities
- Changes to targets or deadlines while you are having treatment
What counts as reasonable depends on your job, your workplace and the size of the organisation. It is worth having an open conversation with your manager or HR team about what would help. Many people find it useful to put requests in writing, so there is a clear record of what was agreed.
Time off for treatment and appointments
Breast cancer treatment can mean many hospital visits over weeks or months. There is no single law that gives a fixed amount of paid time off for cancer appointments, but reasonable adjustments under the Equality Act 2010 can include allowing time off for treatment without it counting against you in the same way as ordinary sickness.
Your contract and your employer's sickness policy will set out how sick leave and appointments are handled. Some employers offer paid time off for hospital appointments as part of their own policy. It is a good idea to ask HR for a copy of the relevant policies early on, so you know where you stand.
If you need help fitting work around treatment, your breast care nurse can often explain what to expect from your schedule, and organisations like Macmillan Cancer Support have work coaches who can talk things through with you.
Sick pay: what you may be entitled to
If you are too unwell to work, you may be entitled to sick pay. There are two main types: Statutory Sick Pay, which is set by the government, and any extra company sick pay your employer chooses to offer.
According to Acas, Statutory Sick Pay (SSP) is £123.25 per week, or 80% of your average weekly earnings if that is lower, and it can be paid for up to 28 weeks. From 6 April 2026, SSP is paid from the first full day of sickness absence, because the old three-day waiting period has been removed. The previous lower earnings limit has also been removed, so more workers now qualify. Your employer can confirm whether you are eligible and how SSP applies to you.
- Check your contract or staff handbook for any company sick pay, which may pay more than SSP for a set period
- Ask HR how long your full pay and half pay last, if your employer offers them
- Keep copies of fit notes (sick notes) from your GP or hospital team
- If your sick pay is ending or you cannot work, you may be able to claim other benefits
If SSP and savings are not enough, you may qualify for benefits such as Universal Credit or, for help with the extra costs of illness or disability, Personal Independence Payment. Citizens Advice and Macmillan's welfare benefits advisers can check what you can claim and help with the forms, which are free services.
Returning to work after treatment
Many people return to work after breast cancer treatment, although it can take time to rebuild energy. Tiredness, sometimes called cancer-related fatigue, is one of the most common reasons people need a gentle, phased return rather than going straight back to full hours.
A return-to-work meeting with your manager or HR is a chance to agree a plan. You might start with shorter days or fewer duties and build up over several weeks. Reasonable adjustments can be reviewed as you recover, so the plan does not have to be fixed forever. If you are worried about coping, your treatment team and your GP can advise on what is realistic for you.
Travel insurance after a cancer diagnosis
Travelling after a diagnosis is often very possible, but you will usually need travel insurance that covers your cancer as a pre-existing medical condition. According to Macmillan Cancer Support, a pre-existing condition is a health problem, such as cancer, that you already have or have had in the past. Some standard policies will not pay out for claims linked to it, so it is important to declare your diagnosis when you apply.
Always answer questions honestly. If you do not declare your cancer, your policy may be invalid and a claim could be refused. Before you buy, it helps to have key details to hand, such as the type of cancer, the date of diagnosis and your current treatment.
- Declare your diagnosis and any treatment, even if it has finished
- Have your medical details ready before you call or apply online
- Compare quotes, as cover for pre-existing conditions can vary a lot in price
- Ask whether you can pay a top-up to include cover for your condition
- Check with your treatment team that you are fit to travel before you book
If a mainstream insurer cannot help, you can use the MoneyHelper travel insurance directory, run by the government-backed Money and Pensions Service, to find specialist firms. All firms listed are regulated by the Financial Conduct Authority (FCA). Under FCA rules, if an insurer cannot offer cover, or the extra cost for your condition is £200 or more (a threshold that applies from January 2026), they must point you towards this directory. Macmillan also hosts an online community where people share which insurers worked for them.
Where to get free, trusted support
You do not have to work all of this out on your own. Several UK organisations offer free, confidential help with work, money and insurance questions after a cancer diagnosis:
- Macmillan Cancer Support: a free helpline, work coaches and welfare benefits advisers
- Citizens Advice: free guidance on employment rights, sick pay and benefits
- Acas: clear information on workplace rights, including a helpline for England, Scotland and Wales
- Your breast care nurse and GP: for advice on how treatment may affect work and travel
Knowing your rights helps you ask for the support you are entitled to. That matters most for people who already face barriers to care. Our charity works to improve early detection and access to support in underserved communities, because a fair diagnosis should come with fair treatment at work and beyond. If you are unsure about your own situation, please speak to your GP or treatment team and reach out to the organisations above.
