Going into my 9th month of Temodar (chemo)

I'm going into my 9th month of Temodar and my latest blood test shows I have more eosinophils (a type of white blood cell) than I should. This could mean I have a weakened immune system. I am actually surprised that it has taken this long to have an abnormal blood test.

I e-mailed my neuro-oncologist to ask what this means and will report back as soon as I have an answer.
