Hi again
Emilia42 thank you for your response. I have also found this forum has helped me to feel less alone in all of this.
Some years ago i worked with a woman who had Huntington's disease. both her children had been tested and her daughter tested positive for the gene.They were both in their early 20's. I felt a kinship to this family through the pain of watching their mother deteriorate as well as the predisposition they had to genetically inheriting this gene.
There is very little if any preventative measures that can be taken for Huntington's and it was at this time that i begun to explore some of the preventative measures available to people who had BRCA1 mutations. I watched a documentary that followed a young woman in her early 20's and documented her decision making process in comparison to her siblings decision making in regards to the choices she made with preventative measures. I also watched a talk show with a mother and her 3 daughters. They had all had preventative surgery regardless of whether they carried the gene or not.
These are big decisions to say the least but unlike some inherited genes there are preventative measures that can be taken with BRCA mutations. I wish you brave young women well. I would love to know of the choices you make. When and if you do.
Hi Hannah,
I'm really sorry to hear about your family history, must be very worrying as well.
I can share with you some information from my personal experience. I'm not sure preventive breast surgery is offered to women under 30s unless they actually have/had breast cancer. Same for ovarian cancer, preventive surgery is not done until you reach 39/40 years old.
The reason why, and this is what my genetic counsellor told me, is because the risk of developing ovarian cancer before the age of 40s is very little (something less than 1% according to data) so the side effects of taking the ovaries away from your bodies (menopause, hormone replacement, etc) would be greater than the risk percentage. Things are different after 40 years old, where the risk exponentially grows, then the side effects would justify it.
I don't know regarding breast cancer, but I suppose is the same - despite, I think, data shows that there is more than 1% risk of developing breast cancer before your 30s and I am the living proof that it can happen :(
I was also reading somewhere that all the preventive surgery are done when someone has completed their family. But I'm not sure how this affects and how it's used or if it was just for trials - to be honest, my mind makes me think "how can I look after my child if I have cancer?" or anyway someone should be allowed to do anything they can to prevent cancer.
The only available thing for ovarian cancer before 40s are trials. The genetic counsellor was telling me about this particular trial where they study if eliminating just the tubes will help in not developing ovarian cancer because they believe it starts in the fallopian tubes and then moves to the ovaries. So it's not really preventive, but they do take the tubes off, leaving the ovaries which still produce the hormones that we need. Because it's a trial, they don't know if it actually works and I don't know if when you reach 40 you can still have the option of preventive surgery. Anyway, for the trial, I remember you need to be at least 30 and have finished your family.
Regarding the IVF, there are options. They can collect the eggs, do the IVF to form embryos and then check the DNA of the embryo. If the DNA contains the BRCA1 gene, the embryo will be discarded. If it doesn't contain the gene it will be implanted in your utero or the surrogate, depending on what you decide. There success rate (at the moment) it's 38%.
Hope it's helpful!
