8/22/2017Hi Lily, I am a breast cancer survivor - diagnosed in my mid-40's with no family history (except for the fact that my sister was diagnosed in the same year - but she was her2+). It was stage III, with 4 or 5 positive nodes. ER/PR+ 100%.

My 18 year old daughter needs to make an informed decision about birth control. I think she shouldn't take it but I told her I'd ask you.

It might be important to note that my mother-in-law was diagnosed this year - a tiny tumor, ER+, she had a lumpectomy and will take Femara. She is 84.

Thank you!

8/22/2017wow, you and your family have dealt with a lot. First, before any decision can be made, it would be useful for you and your sister to meet with a genetics counselor and get genetic counseling and testing. if you carry a gene mutation then your daughter has a 50% risk of also having the same gene mutation. if you don't then that bodes better for her in the future. the BC pill dosage today is tiny compared to what it was say in the 1970s and 1980s. research has shown that being on a low dose pill today for less than 5 years doesn't appear to increase risk. there isn't much research though if the patient carries the breast cancer gene mutation. so meet with a genetics specialist to discuss this further and get more personal information about your genetic status before deciding anything.
