A new DNA test has been developed by Qiagen to identify the human papillomavirus (HPV), a virus found to be associated with cervical cancer. Scientists state that this new test is an improvement on current testing methods and might eventually replace the Pap smear test as a way to diagnose HPV.
Early diagnosis is key in fighting all types of cancer, including cervical cancer. In fact, the most common pitfall doctors fall into regarding patients with cancer is failing to diagnose cancer early enough to provide treatment. This new test could reduce the number of missed cervical cancer cases and improve cancer patients’ outcomes.
The optimism around this new DNA test is based on the results of an 8-year study of 130,000 women in Indian that was recently published in the New England Journal of Medicine. The study, financed by The Bill and Melinda Gates Foundation, revealed that a single screening with the DNA tests met all the same standard as all other methods of early diagnosis of cancer.
Similarly, a study by the University of Chicago reports that a predictive model based on family history of breast or ovarian cancer can aid genetic counselors in diagnosing breast cancer in African women. Development of genetic testing for different ethnicities is important because research shows that genetic mutations vary among racial and ethnic groups.
