1) Is the only issue the cancer or are there other medical conditions that need notifying. Look at the big picture.

2) Do your doctors say you are fit to drive now? DVLA will write to them and if your doctors say No then it is a waste of time applying until they say Yes or Maybe – I have added in an additional reply relating to a close friend of mine who got a Maybe –(unless you need the refusal to get a free bus pass). I had to have a lot of tests (have detailed what I went through below) before I got the Yes I needed after GP said a big fat No! (I didn't have brain cancer but did have suspected seizure and with seizure history there can be a lot of tests)

When I had a blackout (suspected seizure) I followed the advice on Gov.uk, stopped driving and notified DVLA.

DVLA contacted my GP who called me in for an interview.

My GP then sent the medical form back and within days I was told by DVLA that I had to surrender my licence. 

The only good thing about the licence being taken from me was that I immediately became eligible for a free disabled bus pass, which I duly obtained.

Next, I had to be referred by my GP and given a complete check over by both neurology and cardiology, including MRI, both normal and sleep-deprived EEGs, treadmill test, stress Echo, 24-hour ECG etc before finally being told I could drive again. 

The doctors didn't assume that the cause of the seizure was neurological. I think whenever anyone has a seizure there is a need to be very very thorough. 

When my licence was initially taken from me, I was told I could reapply after a certain period, subject to my doctors saying I was fit to drive, which didn't happen until both neurology and cardiology had finished with me! There were a lot of cardiology tests because unfortunately I started seeing stars when undertaking the treadmill test and there were some minor ECG abnormalities. 

Finally, after a period of not driving then re-applying, I got back a full driving licence.

Unfortunately, I subsequently had another neurological issue which meant I had to inform DVLA yet again and not drive for a period. After that, I was allowed to drive again. However, my licence was medically restricted and limited to one year.

And now my licence needs renewing again and I am currently not driving.

Good luck!
