Study of genomic DNA leads to new advances in cancer diagnostics
...xists for future diagnostic applications. The cell smear assay, which is similar to methods commonly used in diagnostics laboratories (such as Pap smears), could be applied to such a purpose. The authors also used flow cytometry to characterize melanomas of varying invasiveness. Further study will be requi...Higher risk for cervical cancer seen among women infected with multiple HPV types
...ng each of the 16,000 patient visits, both the pap smear and HPV tests were administered. The mean follow-up time of the study participants was over three years. When Franco, Trottier and their colleagues analyzed the data about all patients (women who did not develop pre-cancerous cervical lesions as we...High HPV concentrations combined with smoking significantly raise risks of cervical cancer

The researchers looked at "Pap" smear examination data from 105,760 Swedish women and identified 499 women with cervical cancer in situ, along with 499 cancer-free women as controls. For these women, they compared their smoking behavior with concentrations (known as viral load) of HPV-1...New test for most virulent HPV strains under study

If the band is not sharp but appears as a smear containing smaller sized RNAs, it is likely that the RNA has suffered major degradation during its preparation. The functionality of the transcript can be determined by in vitro translation. Handling RNA Ribon...Virus Level could Predict Cervical Cancer Risk
...ated early, it is curable in most cases.// The Pap smear is the standard screening method for the disease. It is used to detect unusual, precancerous changes in cervical cells.
