A new study suggests menstrual blood testing could offer a simple alternative to cervical screening. Researchers found that a sanitary pad fitted with a blood sample strip can detect HPV, the virus causing most cervical cancers. The test allows women to collect samples at home without clinical procedures.
Researchers in China compared menstrual blood samples with clinician-collected cervical samples. The study involved more than 3,000 women aged 20 to 54. Results, published in BMJ, showed similar accuracy for detecting serious cervical cell changes. The menstrual blood test detected abnormalities with 94.7% sensitivity, matching standard screening.
Experts say the approach could help reach women who skip current screening. Cancer Research UK welcomed the innovation but said larger trials are needed. The Eve Appeal called the method promising but noted it would not suit everyone. Researchers say offering more screening options could improve participation and save lives.
