... interval. Have taken 7. Doctor wants to give me 1 more treatment, but WBC dropped from last treatment from 4.2 to 2.1. Said it was because Ihave been on it to long. Is this true? I have stage 3 going into stage 4. I have never been on anything else. I could never get my WBC count up past the 4.2. Also continue to have low protien count.I am 56 years old now. He first told me I was to receive 12 months, now has changed his mind.
