Hi,
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 etc.
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.
Take care.
