Is it necessary to run the terrain protocol before beginning treatment? 10 days seems like a long time before getting on with treating cancer. How long will I need to account for the contact method in the 4 generator cancer protocol?

One option is to just dedicate one generator to running the terrain protocol and let it continue to loop the whole set - basically its automatic.
Bryan created a preset that contains the entire terrain protocol here:

Another option is to follow the documentation of the terrain protocols here:
http://www.spooky2.com/downloadsPage/index.html look for these under waveforms and presets:
"Terrain Protocol 07042016"
Or for cancer: "Spooky2 Cancer Protocols Pack 11042016"

Both of these have a pdf giving the instructions and show what programs to run on which generator.

Contact mode is normally only a few hrs a day maximum but read the documentation for details, you can then use the generator for other tasks.

Alternatively you can run parts of the terrain protocol on separate generators.
For the first time through I would allow metals sections to complete once before doing other things as per the doco.
