CBC results = normal WBC except for one type (don't know which one) that is a little elevated - she said it could be caused by acne, scared of cancer!

Not a screening tool. A CBC by itself is not a very good screening tool for cancer. The results you reported are not consistent with a blood cancer and beyond that it provides little evidence either way. If your listed anxiety disorder makes you worry continually about cancer, or anything else, work on the issue with a therapist who can confer with your doc to see if or when additional studies would be worthwhile.
Cancer unlikely. If you need further clarification do feel comfortable about discussing the results further with your doctor, it will not be out of line and a proper explanation will help to put you at your ease. take care.
