My wife was diagnosed with CML in November 2019 and has been on dasatinib since. Her counts have always been low, but recently her dr's office has suggested that a bone marrow biopsy might be needed, and we are trying to understand why (they have been vague as to why and the value of the test).
Here are some of her counts (they have been around these levels since treatment started back in late 2019 / early 2020:
Her PCR hit a low of 0.07, but then went up to 0.09, 0.11 and is now at 0.1.
Any thoughts as to why a bone marrow biopsy is needed and if there is anything that should be of concern based on her counts?
