Neuroendocrine Tumours (NETs) – Vitamin D (Cholecalciferol / Ergocalciferol)
Vitamin D deficiency is demonstrably more common in people with neuroendocrine tumours (NETs) — but that does not automatically mean your deficiency is caused by

After diagnosis in July 2010, with the exception of a planned holiday to Turkey prior to my ‘big surgery’, holidays were put on the back burner, there were too many problems and too many risks – not least of which was the lack of overseas insurance cover for my condition. After 2 years of treatment including several surgeries, I was feeling more confident and my body had become stronger, holidays were put back on the agenda, but nothing too strenuous, nothing too far away. We stuck to Europe over the period 2012-2014.
However, in 2015, I was getting more confident and managed to get back to one of my all-time favourite places – California. A total round trip of 21 hours on an airplane, around 1200 miles/20 hours of driving from beaches to deserts and mountains and back again, 8 different hotels, and some great sights and adventures including 200 miles of driving in the Californian ‘wilderness’ picking up some sections of Route 66. The picture in the blog needed a ‘white knuckle’ cable car ride up to 8500 feet followed by a 2-hour hike in noticeably thinner air. Worth it!
Did I have issues? Yes. Were they inhibiting? Not really. Was I exhausted on return? Yes. Did my travel insurance cover me for NET treatment? No. Was I mad? Yes! Was it worth it? Absolutely, I was extremely confident I wouldn’t have a NET problem and was therefore happy to take the risk (everyone needs to take their own decisions). My travel insurance at the time covered me for all other medical emergencies worldwide.
Note – in 2022, I’m now covered for NET treatment worldwide. Also, for UK peeps, the E111 has been replaced by the GHIC – read more click here.
Holidays now have to be planned around treatment, mainly monthly injections – not too much of a drama. I take all my other prescription drugs with me to last the period of the holiday.
Cancer doesn’t take holidays, but I do. Sometimes, you just have to get on with it.

I would also mention those who contributed to my “Tea Fund” which resides on PayPal. You don’t need a PayPal account as you can select a card but don’t forget to select the number of units first (i.e. 1 = £4, 2 = £8, 3 = £12, and so on), plus further on, tick a button to NOT create a PayPal account if you don’t need one. Clearly, if you have a PayPal account, the process is much simpler
