I have positive family history of breast cancer, what should I do ?

Women with family history are always worried , and some may even come for a check up every month. The risk of breast cancer is higher if you have a first degree relative diagnosed with it; eg : mother, sister or daughter, especially if a relative developed breast cancer under the age of 50.

However, most women who have a close relative with breast cancer will never develop it. Out of every 100 cases of breast cancer, only 5 to 10 are related to family history or genetic factors. 

The American College of Radiology (ACR) recommends that all women have risk assessment by age 25, to determine when and how they should start screening. High risk women (women who have a 20% lifetime risk or more) may need to start mammograms earlier (between age 25 – 40) and may also need annual breast MRI scans.

Who are women at high risk for breast cancer ?

Higher risk may be indicated by: 

• A lifetime risk of breast cancer of 20% or more, calculated using a risk assessment model.
• A known genetic mutation, such as in the BRCA1 or BRCA2 genes.
• An untested first-degree relative (parent, sibling, or child) who is a known carrier of a BRCA mutation.
• Ashkenazi Jewish ancestry, which is associated with a higher likelihood of BRCA mutations. 

Next steps:

Talk to your doctor, to determine the most appropriate screening plan.

• Have a risk assessment performed, ideally by age 25.
• Discuss the possibility of genetic counseling and testing with your doctor.
• Create a personalized screening schedule that may involve starting mammograms earlier and including supplemental MRI.
