Ethical issues surrounding genetic data

Genetic screening for breast cancer in at-risk women remains a major ethical issue given that it rejects controversial images namely:? a frightening image of cancer;? a positive image of cancer screening.This system which is aimed at women aged 50 to 74 invites them to take part in a two-part screening examination every two years: a first reading a bilateral mammogram in two incidences (face and oblique) analyzed by a radiologist followed by a second reading if the mammogram is negative. However new genetic screening techniques for at-risk individuals have revolutionized the way in which breast cancer is now treated at a very early even preventive stage. For this reason the concept remains a controversial one since in these cases we're not talking about sick people but healthy people who could potentially become ill in the future. This is why I asked myself the following question: What is the ethical viewpoint regarding genetic screening for breast cancer in women at risk with a view to preventive management?
