• Known to have a gene mutation that increases your risk for breast cancer (e.g. BRCA1, BRCA2, TP53, PTEN, CDH1)
• First-degree relatives of someone who has a gene mutation that increases their risk for breast cancer (e.g. BRCA1, BRCA2, TP53, PTEN, CDH1), have already had genetic counselling and have chosen not to have genetic testing.
• Assessed at a genetics clinic (using the IBIS or BOADICEA tools) as having a 25 per cent or greater lifetime risk of breast cancer based on personal and family history
• Have had radiation therapy to the chest to treat another cancer or condition (e.g. Hodgkin Lymphoma) before age 30 and at least 8 years ago
