MRI Frequency

Is anyone getting their MRIs more frequently than every 8 weeks and/or regularly using gamma or cyber knife?

One of the support foundations recommended that I get a MRI every 6 weeks (my tumor is currently stable, dx 11/2014).  They opined that this makes it easier to catch the tumor while it is small thus lending the tumor management to either gamma or cyber-knife surgery.  Having heard stories about how fast the tumor can grow, this strategy appears to make sense to me and could allow for "routine management" of the tumor in a less invasive manner.  (I realize a multi-focal or certain tumor locations require additional considerations.)

I'm guessing that there are complications with respect to getting too much radiation (from both the procedure and MRIs), having insurance pay for it, and inconvenience of more MRIs.  It seems to me however, that perhaps these are outweighed by the benefits of potentially using gamma/cyber-knife rather than traditional surgery, taking chemotherapy, or scrambling to find an appropriate clinical trial.

Any thoughts?
