Hi @Joarden - I had 4 weeks radiation & apart from warmness in the breast & some reddening - very little in the way of Side Effects. I think the mental preparation for it is worse than the actual procedures!!
Where abouts are you (city/Town? You can add it to your profile so others know too.) Can you contact the Welfare officer of the Hospital where you are having the Rads done? They may have an arrangement with drivers to get you there & back. I know that where I am, travel is organised for patients. (1.5hrs each way)
Having to rely on public transport would be a real pain. :(
The machine broke down for me too! LOL
Just make sure you keep the lotions/potions up to your area being 'nuked' .... and for at least 4 weeks (or more) afterwards as well, as the area will remain very 'warm' for some time.
Take care, stay safe xx
