Cervical cancer
Cervical Cancer screening is the most successful and widely used example of asymptomatic screening worldwide. The tests used for it are cervical cytology and more recently (in certain health systems) the detection of human papillomavirus high-risk types (HR HPV test).
In countries with organized screening systems such as Great Britain and Scandinavia, women who belong to the eligible age groups, are invited at regular intervals via their family doctor to participate in cervical screening.
In Greece screening is opportunistic meaning that women present for screening on their own initiative. However, there are official guidelines describing the proposed frequency of screening, eligible population and appropriate tests, published by the Hellenic Society of Obstetrics & Gynaecology.
