Queensland pensioner and grandmother, 69-year-old Yvonne D'Arcy, who has twice beaten breast cancer, won an important victory in the High Court on October 7. D'Arcy brought a landmark legal challenge against US-based biotech company Myriad Genetics after it was granted a patent over the BRCA1 and BRCA2 genes. Mutations in the genes dramatically increase a woman's chance of developing breast and ovarian cancer.
