Hi Dan,

Welcome to OCF. I am quite sure that you will not only be able to travel but also help organize both the weddings. Radiation can be physically draining but your determination will help you get through. In my honest opinion, do not delay the treatment.

My father had 33 cycles of radiotherapy (~60 Gy) with weekly Cisplatin. He did not have PEG and maintained his weight all along (just lost some 12 Pounds). He used to drink lot of water and eat whatever he could swallow (with sip of water). He used to drive car himself to closest metro station (4 miles) and then take up train to hospital (15 miles) and back.

Tail-end of the treatment was difficult but then when you see that it is ending, you somehow get the energy. Flying should not be an issue but you may stuffy or painful ears after the flight.

My advice:

- Avoid sun
- Drink lot of water, if you get Coconut water in your area, drink plenty.
- Avoid caffeine, acidic/citrus stuff
- exercise regularly (Yoga may help) and be positive!

Take care and hope to hear from you more, especially about the wedding plans.
