Not necessarily and probably not - could be many reasons.
PSA results should be in not later than 72 hours,

It is much, much more likely to be a sign of an infection or something
else.  These days, prostate cancer is rarely diagnosed because of
explicit symptoms,  which  usually only occur pretty far along in the
disease.   Almost all cases are diagnosed because of abnormal PSA
readings or because the doctor feels something unusual when examining
your prostate with his finger.

Tell your doctor about any symptoms, but don't worry about them otherwise.
