Risk factors for cervical cancer development: what do women think?

The current cervical cancer prevention strategy is exclusively directed towards screening, without taking into account any relationship with sexual risk factors. The introduction of human papillomavirus (HPV) detection into the screening procedure implicates that we should give attention to this relationship. The aim of this study was to investigate what knowledge women have of the relation between HPV and cervical cancer.

Rather than asking about HPV specifically, we suggested 20 risk factors for the development of cervical cancer, including viral infection, and asked 73 women visiting their general practitioner, 67 women visiting a lecture on risk factors for cervical cancer and 28 female students in biomedical sciences to rate the importance of these risk factors on a scale of 1-5.

Genetic factors were rated highest with a mean score of 4.5. Bacterial infection ranked second highest with a mean score of 3.8. Smoking ranked fourth at a mean score of 3.6, whereas viral infection shared the sixth place with number of sexual partners with a mean score of 3.4. The presence of high voltage power lines and physical activity appropriately scored the last two places at 2.4 and 2.2, respectively. Twenty-one women suggested a role for sexually transmitted agents, but only five women (3.1%) could actually pinpoint HPV.

This enquiry indicates that the risk factor 'genetic factors' was over-rated, while knowledge of the most important risk factors, i.e. smoking and sexual habits and (sexually transmitted) infections, would appear to be present to a moderate level in our population. However, knowledge of the role of HPV in cervical cancer development is lacking.
