Such risk stratification could form the basis of ‘personalised’ screening, particularly for breast, prostate and ovarian cancers which occur commonly in the population…
This poses the question of when genetic testing for risk assessment should take place. The offer of such a test during childhood, possibly as part of a wider risk assessment package for a range of adult disorders, was raised by experts attending a [Collaborative Oncological Gene–environment Study] international workshop and this paper examines the pertinent issues that might arise…”
