Family History

Hi.  In 2012 my mum, aged 62, was diagnosed with triple negative breast cancer.  In 2020, aged 38, I was diagnosed with ER+ and PR+ breast cancer.  I also had an aunt who died when she was 38 of breast cancer (type unknown).  Due to the family history i was meant to have yearly mammograms from 40.  After my diagnosis i was genetically tested which fortunately was negative and was told my daughter who is 13 would need mammograms from the age of 40.  However my mother in law has recently been diagnosed with HER2+ breast cancer.  Does this increase the chance of my daughter getting breast cancer?  She is aware and i have spoken to her about checking herself regularly but the thought of her also going through this at some point in her life terrifies me.  I know no one can give me a definite yes or no but due to both nans and me having breast cancer i am genuinely worried about what the future may hold for her. 

Hi Hammond1170 

Thank you for posting. 

It’s understandable that you feel worried about your daughter’s risk of developing breast cancer. 

The biggest risk factors for developing breast cancer are being a woman and increasing age. It sounds as though your mother in law’s breast cancer has been diagnosed at an older age. Your mother in law’s diagnosis does not automatically mean that your daughter’s risk of developing breast cancer increases , unless she also has a significant family history. 

It may help to contact the genetics clinic where you had your genetic testing and talk to them about your worries. They will be able to advise if there is any additional risk for your daughter.  

It’s good to hear that you have taught your daughter about breast awareness and encouraged her to check her breast regularly. Your daughter may also find it interesting to read about some of the things teenage girls may notice about their breasts.  

It sounds like it has been a difficult time for you since your breast cancer diagnosis, having also had close family members with breast cancer. We offer a range of supportive services for anyone affected by breast cancer. You can find details about all of these services in the link.
