DIY smear test works for cervical cancer
A do-it-yourself smear test could enable millions of women in poorer countries to head off cervical cancer.
Eighty-five per cent of cervical cancer cases occur in developing countries, where screening for pre-cancerous changes is rare due to difficulties in obtaining samples and a shortage of cytologists to interpret them. Testing for DNA from the human papillomavirus (HPV) that causes the disease is an alternative method. A kit created by Qiagen of Gaithersburg, Maryland, enables women to take their own cell sample, which is then posted to a lab.
