Information Living with thyroid disorders Thyroid cancer - travel insurance advice If travelling in Europe you should apply for European Health Insurance Card (EHIC) which has replaced the E111. EHIC doesn't replace travel insurance but enhances it by entitling the bearer to reduced cost or sometimes free treatment in Europe. EHIC covers treatment for existing medical conditions. It is available free of charge from the NHS website. Please be aware of unauthorised websites that charge for this service. Please note you should prepare for possible changes to your access to healthcare when the UK leaves the EU if you're a UK national travelling to the EU, Norway, Iceland, Liechtenstein or Switzerland. If you're planning to visit after the UK leaves the EU, you should continue to buy travel insurance. The EHIC may not be valid if there's a no-deal Brexit. This will depend on arrangements with individual countries and might mean you need to pay for treatment in full. You should always give clear, correct and precise information to the insurance companies. All questions should be answered honestly and truthfully. It's important to declare all medical conditions otherwise under UK law the insurance will be null and void. Some insurance companies will give a quote for a regular premium but that may exclude Thyroid Cancer. Quotes that include cover for Thyroid Cancer may have higher premiums than normal policies. Compare single trip and annual policies, if travelling twice or more in a year it will often be cheaper to buy an annual policy. Be prepared to spend time shopping around for quotes. You should be prepared to speak to someone at the insurance company and explain your situation. It is recommended that medicines, including levothyroxine, are carried in hand baggage in the original packaging. If travelling for any length of time split medicine supplies over two bags in case of loss or theft.Take more medication than needed in case of any delays. Take a prescription script with you in case you need any medical treatment or lose medication. Keep medication out of the heat in a cool place. If you have recently had radioactive iodine treatment you may trigger radiation detectors at airports and seaports. This can occur for up to 95 days after treatment. If travelling within this time it is advised that you ask for a letter from the hospital where you had the treatment explaining this. The Macmillan guide to travel insurance is revised annually and includes a list of travel insurance companies that cover certain types of cancer. This may be especially useful for people who are currently having treatment or have recently completed treatment. No guarantees of cover are given.
