Thanks for the query.
Urine test won't help in diagnosing the cervical cancer
Usually cervical malignancy will present with symptoms like post coital bleeding, increased vaginal discharge
, pain during intercourse
As you told pap smear
is needed as a screening test.
In your age cervical malignancy is some what rare.
Starting the sexual life at early age is one risk factor.
After investigations only we can come to one conclusion.
