It's again been a while since I posted an update.  I had a fresh MRI today, and the tumor hasn't changed significantly in the last couple of months.  The shunt has been helping the hydrocephalus, which reduces the excess pressure on my brain, so I'm more functional and comfortable.  The oncologist doesn't feel that it makes sense to schedule another MRI unless there are changes to my symptoms. 

Each trip to San Francisco to see doctors seems to be a new adventure.  This time, we made it as far as Vallejo before the car died.  If all goes as planned, we'll be getting a ride to Benecia tomorrow to pick up the car and then go back to Folsom from there.
