A 35-year-old woman has a strong family history of breast cancer: her mother and aunt both developed early-onset breast cancer. She is considering undergoing genetic screening for mutations in the BRCA1 gene. Explain the social and ethical considerations that she and her healthcare provider should take into account when deciding whether to proceed with the screening.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
