Mary, I can't say what the doctors will decide, but usually if the WBC drops too low, chemo is delayed until it comes back up. I developed a fever twice during 8 chemo treatments and had to take antibiotics. Fortunately, for me each time my WBC got high enough by the time my next chemo was due to get my treatments on schedule. However, it is not unusual for chemo to be delayed if the counts don't come back quickly enough. Everyone responds differently to chemo, and no one can predict what her WBC will do. It sounds like her doctors are monitoring her situation closely.
