My mum was diagnosed with melanoma (skin cancer) for the second time late last year. She is undergoing treatment via chemo pill and is responding very well so far. She wants to take the family (5 adults & 1 child) to Florida in April next year for 2 weeks and our only reservation about booking is what if her condition deteriorates and what protection would we have over the holiday. We'd have to ensure we had the best travel insurance in place but not sure if she would even get the necessary cover. Has anybody experienced anything similar and can advise?
