Genetic testing for breast cancer?

[HotI]

Hi

In order to have genetic testing, you need to have strong family history of breast cancer or associated cancers. Only 5-10% of breast and ovarian cancers are caused by mutations in the 'breast cancer genes' BRCA1 and BRCA2.

These criteria can be used by GPs to work out whether a woman should be referred to a genetics clinic to see if genetic testing is appropriate:

# Have a close relative (parents, grandparents, children, grandchildren) with a known mutation in BRCA1 or BRCA2

# Have close relatives across more than one generation (for example, a mother and a sister) that have been diagnosed with early-onset (before age 50) breast and/or ovarian cancer

# Have an individual family member who was diagnosed with both breast and ovarian cancer

# Have had cancer in both breasts, especially if one or both cancers were discovered prior to age 50

# Are of Ashkenazi Jewish heritage with breast cancer before age 50 or ovarian cancer at any age

# Have a male family member with breast cancer

# Have other associated cancers/conditions

Testing usually begins with the affected person (someone who has, or has had a cancer associated with BRCA1 or BRCA2). If a mutation is found, then other family members can be tested. If a family meets the criteria (of being at high risk) then genetic testing can be provided at no cost.

Surveillance is really important for all women, as breast cancer is so common. Regular breast checks, even getting your GP to perform a check, can help pick up lumps early. And the earlier cancer is detected, the higher your chances of recovery,
