blasting did not decrease. . . . .

i had my bone marrow aspiration done on friday and the result was on wed. we were excited that hopefully this time the blasting(cancer cells) would have decreased a lot. but on wed when we went to see the doc we found out that the result was not good. the blasting had not decreased even a little bit since the last chemo.   last time the blasting was 68% and now the blasting was 75%. my cancer cells had not decreased but they had increased even more.   next wed i have another appointment with the doc and then they will tell what they plan to do next.
