My blood counts were low throughout treatment, although never low enough for hospitalization. This delayed my 2nd round, and almost nixed the 3rd. My MO said that missing the last chemo round was NOT going to affect prognosis!
I am eleven months out from TX, and my white blood cells are still in the 2's. That being said, I have not caught a cold, virus, or catching illness of any kind in the past year, and cuts and scratches all heal well! I was sent to a hematologist, but they said I was fine---no weird blood disease or anything.
Anecdotally, my acupuncturist has told me to eat "red foods" to build white blood cells and I have complied with this. I will have my blood tested in a few days--we'll see if the diet changed anything!
