What Causes Elevated WBC And Neutrophil Count?

Ive had some blood tests done recently and The last ones were done a week apart. One on 9/21/17 and the other 10/12/17. the first one showed high wbc as 13.4, normal rbc and high neurtophils (absolute) 9.0 and high lymphs (3.6) the second one showed high wbc and rbc as 12.7wbc and 5.30rbc . the neutrophils and lymphs have been high since january 17.. why are these high and is this is a sign of cancer or something else? Im scheduled to go to a hematologist but havent gotten appt yet and im freaking myself out thinking its lukemia or tumor or hiv or anything.. Im just thinking any possibility. I know you cant give direct answer but please tell me if these numbers are cause for concern. Ive been extremely tired, getting lots of headaches, my head feels heavy and almost like its swaying. but i think that stuff has to do with a strain on my eyes maybe so maybe not connected to above? I only take meds for high cholesterol and just vitamins nothing else.
