Testing period blood for signs of cervical cancer could be an accurate and convenient way of screening for the disease, researchers say. In the UK, the current NHS test involves a nurse or doctor taking a sample of cells from the cervix, but testing period blood would be an even less invasive option, say the Chinese researchers behind the new study in the journal The BMJ. However, experts said period blood tests are not an immediate alternative to current cervical screening because only women who menstruate could use them. Others said the study could have overestimated the performance of the test because not all women had a biopsy - a more detailed test - to double check the result.
