I was diagnosed with CML and given Gleevec 400 ml. After taking gleevec for 2 weeks doctor took additional blood test. My WBC dropped from 36.5 to 7.1 and all other blood counts came down to normal range. I'm wondering if gleevec could give such fast hematological response or I was possibly misdiagnosed originally. I don't and didn't have any symptoms, my spleen and liver weren't enlarged, no enlarged lymph. Should I get second opinion asap? Please, help me.
