- Two or more family members have had breast or ovarian cancer (especially if they are close relatives – your mother, sister or daughter – and/or if they were younger than 50 when their cancer was diagnosed)
- You have previously been diagnosed with invasive breast cancer
- You have previously been diagnosed with a pre-invasive breast disease such as ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS) or atypical hyperplasia of the breast (AH)
- You have a mutation in a gene known to increase the risk of developing breast cancer.
The NBOCC has created a Familial Risk Assessment – Breast and Ovarian Cancer (FRA-BOC) its an on-line tool designed for use by health professionals. Fill out the assessment here.
We are now in the generation of genetic testing. Not all family histories are related to a genetic fault. Always keep in mind only 5-10% of all breast cancer cases are due to a genetic fault or strong family history.
If you are considering genetic testing read through the other sections on our website.
