In a groundbreaking study published today, Rice University bioengineers unveiled the immense potential of DNA tests in expanding access to cervical cancer screening. The study, conducted by a team of scientists from renowned medical institutions, has demonstrated how these tests can revolutionise early detection and prevention efforts.
Traditionally, cervical cancer screening primarily relied on Pap smears and HPV tests, which posed logistical challenges in resource-limited areas and often required specialised medical facilities. However, this new study introduces a game-changing approach, utilising simple DNA tests that can be administered in a non-invasive and cost-effective manner.
Nine engineers from Rebecca Richards-Kortum’s lab at Rice analysed DNA samples for more than two years. They targeted specific genetic markers associated with cervical cancer, and found that the new tests provided highly accurate results. Moreover, they proved to be equally effective across diverse populations, offering great promise for addressing disparities in access to healthcare.

The researchers demonstrated a six-step test for HPV16 and HPV18 i.e. two types that account for about 70% percent of cervical cancer. The diagnosis delivered results in 45 minutes
The findings have prompted calls for further research and the integration of DNA tests into national cervical cancer screening programs worldwide. Experts believe that this approach will lead to earlier detection of the disease, thereby improving treatment outcomes and reducing mortality rates.
