A breast cancer diagnosis does not have to mean the end of holidays, weekends away or visits to family abroad. Most people with cancer can still travel, often with a little extra planning. The key is to think ahead, talk to your treatment team and sort out the practical things, such as insurance and medicines, before you go.
This guide explains the main things to think about when travelling during or after breast cancer treatment. It is general information to help you ask the right questions, not personal medical advice. Your GP, hospital team or specialist nurse know your situation best, so always check with them before booking or boarding a flight.
Flying after breast surgery
Whether it is safe to fly after surgery depends on the type of operation you have had and how your recovery is going. Breast Cancer Now advises that, in general, after breast surgery you should wait at least a few days until you have recovered before flying or travelling long distances. Because there is a higher risk of blood clots after surgery, it is best to check the timing with your own treatment team.
If you have had breast reconstruction, the advice can be different, and some people are told to wait longer before flying. Because the timing varies so much from person to person, the most reliable answer will come from your surgeon or breast care nurse, who can advise based on your specific operation and recovery.
- Ask your surgeon or breast care nurse directly when it is safe for you to fly.
- Tell them how long your flight will be, as longer journeys carry a higher risk of blood clots.
- Build in extra recovery time before a long-haul trip rather than booking tightly around your operation date.
- Keep a note of your surgery date and any advice you are given, in case your insurer or the airline asks.
Cancer Research UK also notes there are some situations where you should get advice before flying, such as if you have had any kind of surgery recently, have a low level of platelets or red blood cells, become breathless after light exercise like walking up a flight of stairs, or have an infectious illness. Your team can tell you whether any of these apply to you.
Blood clots and long journeys
Sitting still for a long time, such as on a long-distance flight or coach trip, can increase the risk of a blood clot (deep vein thrombosis, or DVT). Macmillan explains that cancer and some cancer treatments can also raise this risk, so it is worth taking simple steps to keep your blood moving.
- Move around when you safely can, and do gentle leg and ankle exercises in your seat.
- Drink plenty of water and go easy on alcohol, which can leave you dehydrated.
- Ask your team whether compression stockings or any other measures would help you.
- Wear loose, comfortable clothing so nothing restricts your circulation.
If you have ever had a blood clot, take a hormone therapy such as tamoxifen, or you are worried about your risk, talk to your GP or treatment team before you travel so they can advise you.
Lymphoedema and flights
Some people develop lymphoedema after breast cancer treatment, where lymph fluid builds up and causes swelling. The NHS and Cancer Research UK explain that after breast cancer this most often affects the arm, hand, breast or chest on the same side as your treatment, particularly if you have had lymph nodes removed or radiotherapy.
If you have lymphoedema, or are at risk of it, you may already wear a compression sleeve or garment fitted by a lymphoedema specialist. Compression garments give gentle, even pressure that helps stop fluid building up. Many people wonder whether to wear theirs on a flight.
There is no single rule that fits everyone, so this is an important question to raise with your lymphoedema therapist or breast care nurse before you travel. They can tell you whether to wear your compression garment in the air, how to look after your arm during the journey, and what signs of swelling to watch for. If you wear a fitted garment, take it as part of your hand luggage so it is always with you.
Travel insurance
Travel insurance matters for everyone, but it is especially important when you have or have had cancer. Macmillan explains that a cancer diagnosis, now or in the past, can affect both whether you are covered and how much you pay. Some standard policies do not cover anything connected to a pre-existing condition, which could leave you facing very large medical bills abroad.
- Always tell the insurer about your diagnosis and any treatment, even if it was some time ago.
- Make sure any pre-existing conditions are accepted by the insurer in writing before you rely on the cover.
- Consider specialist insurers who arrange cover for people with cancer or other medical conditions.
- Compare a few quotes, as prices can vary a lot between companies.
- Check what the policy covers, including treatment abroad, getting you home, and cancelling the trip if your health changes.
If you are travelling in Europe, a UK Global Health Insurance Card (GHIC) lets you get medically necessary state healthcare in the European Economic Area and some other countries, on the same basis as a resident, which may mean it is free or at a reduced cost. According to the NHS, a GHIC is not a replacement for travel insurance and does not cover everything, so you should have both. You can apply for a GHIC for free through the official NHS website, so be wary of unofficial sites that charge a fee.
Vaccinations
Some destinations need particular vaccinations, but cancer treatment can change what is safe for you. Macmillan explains that treatments such as chemotherapy, and some targeted or immunotherapy drugs, can weaken your immune system. If your immune system is weakened, live vaccines may cause a serious infection, so you must not have live vaccines while you are having, or have recently had, chemotherapy or radiotherapy.
Inactivated (non-live) vaccines are generally considered safe, although they may work less well if your immune system is weak at the time. Because the timing is so important, arrange any travel vaccinations well in advance and discuss them with your cancer team, GP or a travel health clinic, rather than booking a last-minute appointment. If you do need a live vaccine to travel, your cancer doctor can advise whether and when it may be safe.
Planning around your treatment
If you are still having treatment, try to plan trips around your treatment schedule rather than the other way round. Talk to your team about the best windows to travel, as some times, such as straight after chemotherapy when your immune system may be at its lowest, are riskier than others.
- Carry your medicines in your hand luggage so you still have them if a bag goes missing, and take more than enough for the whole trip.
- Keep medicines in their original, labelled packaging and ask your team or pharmacist for a letter listing what you take, especially for injections or controlled drugs.
- Take a summary of your diagnosis and treatment, plus contact details for your team, in case you need medical care while away.
- Find out where the nearest hospital or clinic is at your destination before you go.
- Plan rest into your itinerary, as fatigue is common during and after treatment.
It is also worth thinking about practical comfort, such as choosing aisle seats so you can move around, requesting assistance at the airport if you tire easily, and giving yourself plenty of time so the journey feels calm rather than rushed.
When it may be better to wait
Sometimes the kindest decision is to postpone a trip. Cancer Research UK lists situations where you should get advice before travelling, including recent surgery, a low level of platelets or red blood cells, breathlessness after light exercise, or an infectious illness. If any of these apply close to your travel date, your team can help you decide whether to go, change your plans, or wait until you are feeling stronger.
Postponing can be disappointing, but good travel insurance that covers cancellation for medical reasons can soften the financial blow, which is another reason to sort out cover early.
Why access to care matters
Planning a holiday around treatment is a reminder of how much good support and information can ease the journey through breast cancer. Not everyone has that support close to hand. Some people face barriers to early detection and to the everyday care that helps them live well with cancer. Our charity works to widen access to early detection and breast health information so that more people get the chance of an early diagnosis and the support they need.
