Total WBC rising all the time....

Really .. you should not worry about the slight increase of WBC's.  Our blodd cells of all types are constantly changing.  If it was a dramatic increase then there should be further investigation at the cause, but your is so slight, it is nothing to worry about at this time.  It could be normal for the body, or there is also the possibility that your body id fighting a slight infection, by the sounds of your symptoms.  There are germs everyday that our bodies come across and our WBC's fight off, most we never even know about and never even have symptoms.  Being you do have symptoms though.. if there is no improvement, your doctor should do a complete blood cell count retest, to make sure that your body is getting better and not worse.  Oh.. and at this point, try not to worry about lung cancer, as your bloods would be all wacky, and there not, if it was something more sinister.  Do you smoke?  If so, it's very normal to have a constant cought, as it is actually a good thing.  It is your body trying to get rid of the garbage in your lungs and cleaning them out.  I do smoke and this consant annoying cough.  If you don't smoke, as I mentioned before, your doctor should and will probably be doing a retest to keep an eye on WBC's.. that's only if you remain symptomatic or for your peace of mind, as most doctors would not even consider your slightly raised WBC count anything to worry about.  Also.. again, please try not to stress about cancer, as it seems all your blood work is in normal range.  If it was cancer, your blood work would show an indication of cancer and it did not.   I hope I was able to help ease your mind...
