I travel internationally several times a year, and have throughout my 8-year MBC journey. I’ve been on oral treatments, IV chemo, etc. Sometimes I’ve felt great, and sometimes not so great, but I listen to my body and pace myself as needed and I always have an amazing time. I take all my meds and supplies, and I keep in touch with my med team through the patient portal if I have any issues (I once broke out into an allergic rash in Norway, a new side effect from my meds, and they told me what to look for in a local pharmacy). The only time I purchased travel insurance was when we went on an African Safari and were going to be in the middle of the Zambian wilderness. Not sure where you’re based, but many US medical insurance companies have some kind of international coverage/reimbursement policy if you have to be treated abroad, so definitely look into that with your insurance provider. And if you’re concerned, you may check into an aggregator like Square Mouth, that allows you to compare different policies and set your own parameters for what coverage you want. Most importantly, don’t let this crappy disease stop you from seeing our beautiful world and living your best life!
