Your marker went from 1697 to 1232.
Me: Yes, that is good news. Back in the Winter of 2010, that marker number was just beginning to rise above "less than 30." Less than 30 means you are in remission, usually (not always but usually). The rise was the start of what has been, so far, a three-year roller coaster ride, with the marker number going up and down, up and down, to well above 2,000, to as low as around 250. But never back into remission.
So: down by almost 500 in the last month is good.
