Hi, i went to the doctor last week with an enlarged lymph node in my neck. I had a cbc and the results came back with a low wbc. Im really worried that its leukemia and thinking back have had similar symptoms, e.g-random bruises, fatigue. Is a wbc of 3.1 likely to be leukemia? also, do symptoms come and go? and if it was leukemia would it show as high or low white blood cells? please help!
