I had a blood test about a month ago and my white blood cell count was slightly high.
I had another blood test just over a week ago at my local walk-in centre and my ESR was slightly high but i presume my white blood cell count was ok in that test.
They done a full blood count along with other things and the doctor said there wasn't anything to worry about.
But what i want to know is can blood tests detect cancer if it's advanced? or can it detect cancer at all? Wouldn't something show up somewhere?
Thanks.
