I thought I had mentioned it, but apparently I didn't.

The tumor in my Dad's lung has decreased by 45% after chemo, which is amazing news.

However, it doesn't seem to mean anything as for now he's only supposed to have a follow-up X-ray every two months to monitor the way the tumor progresses. I personally don't get it - I mean for god's sake, half of the thing is gone already, just TAKE IT OUT, DAMN IT - but obviously it doesn't work like that.
