Management of a woman with a family history of breast cancer

Recent media publicity about breast cancer has caused concern for many women. Most women with a relative with breast cancer are not at substantially increased risk. NICE released revised guidelines in 2004 classifying women into risk groups. When a woman presents with concerns, it is important to take a full family history. For those that fit into a high-risk group, referral to tertiary care may be appropriate. Genetic testing of BRCA1 and BRCA2 may be offered in families where there is a living affected family member to test first and can be offered to unaffected individuals when there is Ashkenazi Jewish background. Breast management options for those at high risk include breast screening from a young age. MRI screening also appears to be useful. The efficacy of ovarian screening is being studied although it is known that prophylactic oophrectomy before menopause reduces the risk of both breast and ovarian cancer. Prophylactic mastectomy is also an option for these women. Genetic counselling and psychosocial support are important.
