6 weeks Chemotherapy

The next stage in my journey is 6 weeks of Mitomycin Chemotherapy.

I was told to expect a call to arrange this since my post MTD meeting on 4th February.
The problem I have is I go away on holiday on 10th April, which is now 7 weeks away, I have been desperately waiting for an appointment since 4th February. I know I just have to wait my turn but I need some advice if anyone can help.

So, I have several choices if they can't fit in my 6 weeks before I go away, which I think is unlikely now.

1, Cancel the holiday, it's insured and it was booked before the diagnosis so covered by insurance, Plus they have accepted my diagnosis without any conditions on my policy for current or future bookings.

2, The Chemotherapy can be done after I return but is that a bad idea?

3, Complete some of the visits before the holiday and the rest when I return, is this possible?

So the two questions are, can the 6 week course be split or does it need to be a continuous 6 weeks? And assuming It can't be split is waiting until I return at the end of April a bad idea for my health?

I did call the urology team last Monday to pose these questions and also made it clear I was not trying to speed things up or jump the queue, and as nice as they always are, they could not answer these questions, they just said they were surprised I had not had an appointment yet and I would have to discuss the questions when the call comes.

So, I am just hoping someone here has some advice on this as I really don't want to cancel my holiday, I really need it after the last few months but my health has to come first and if my holiday needs cancelling and an insurance claim then it will have to be.
