Genetic tests available for breast cancer detection

Posted by BRCA @biohazard12, Oct 21, 2019

Would like to know all the different DNA tests available for testing the susceptibility to Breast cancer. Required for an individual (daughter 33 years of age) whose mother was a cancer patient with the following (FISH Her-2/neu test is borderline, ER, PR positive). Later on detected with stage 4 (multiple sclerotic lesions in the liver). Background: The cancer patient's sister and mother are healthy individuals and are presently over 50 and 75 years of age respectively.
I want to get the individual tested for

I wish I would have done the testing prior to treatments. I was diagnosed with triple negative in ‘15. Had a lumpectomy as it was found early and small, then chemo and radiation. I was 65 but wondered why it turned up so late in life. So I saw the genetic counselor and we decided to look at my relatives and there was a number of my generation that had the secondary cancers of the BRCA cancers. I agreed to be tested and I am BRCA2. So I decided I needed to do more to keep the cancer away. Fallopian tubes and ovaries removed in ‘17, bilateral mastectomy and reconstruction in ‘18. Now having all this behind me, I feel great and very pleased with all my care at Mayo Rochester.

I am 61, I had biopsy/surgery on one breast in 2007 an the other in 2017. Both benign. However my mom had breast cancer in 2000 had lumpectomy, chemo an radiation. 3 mths later my mom’s mom, my grandma had breast cancer an had a mastectomy. One of my grandmother’s sisters an her daughter brother had breast cancer. Today on my 6 mth follow my daughter says we should do the genetic testing. So I had the blood test done. They say it takes 2-3 weeks to get results. I say what my mom went through with chemo an radiation an what our family went through. I do not want to go through what my mom did or have my family go through it. Should I be positive for any, would you or anyone recommend having the prophylactic mastectomy?

I’m 61 years old, my mother had breast 19 years ago had lumpectomy, chemo an radiation. 3 mths later my mom’s mom had breast cancer an had mastectomy. One of my grandmother’s sister an her daughter both have also had breast cancer. I had my first biopsy in 2007 an my second in 2017, both removed an negative. Have been goin every 6 mth since for mammo an ultra sound. Today when I went they decided I needed to do the genetic testing. I have a daughter an two grandaughters. As I said I’m 61, my mom was 63 I saw what she went through an how hard it was for all of us. That is not something I want to go through or have my family go through.

My question is is my test come back an I have the gene with my family history an my two previous biopsies, would you opt to have the prophylactic mastectomy while you are still in good health?

Which gene was discovered in your genetic testing? What is the percentage risk for you?

Please have the daughter see a genetic counselor. They will be able to give her options that insurance should cover under the NCCN guidelines with a first degree relative with a cancer. Best
