dear chandra 
we should need other details or other symptoms to diagnose a disease for you 
but let me tell you that why are you suspecting onco directly and going to see them before going to 
oncologist better check this symptoms 
1. see about 
fever for a week, time of occurance, duration and aggravation of the same
2. weakness you mentioned in what time, after your routine activities or does not matter with that
3. see about the diet pattern, if it has been reduced ?
4. check for breathe whether normal or you get stressed and difficult breathing after a little exertion also 
in body if anywhere u will get infection your counts will rise
please tell us the exact counts and inform us about the 
ESR level also 
which will give us exact idea to diagnose
thanks a lot
