Are you a breast cancer survivor who happens to be childless?

I have been a member of this online network since 2014, just after my diagnosis. At a recent breast cancer seminar at a city near where I live, something hit me like it hasn't in all this time, the subject of survivors who happen to be childless. I thought to myself, "Noone talks about this. Why?"
This has led me to do my research, as you do, I found this demographic of women are at higher risk of breast and ovarian cancer. It is explained this way, you are at a lower risk of diagnosis if you have children.
Interesting I thought, Nuns are at a higher risk of breast cancer and ovarian, not that I am a Nun but an interesting statistic that gets me thinking. Which brings me to why I am posting.
I am putting it out there in a courageous way to see if there is another like me. Courageous because for 30 years after my extensive efforts to go forth and multiply I walked away childless. The one thing I learned was to keep it to yourself as I found there were lots of people willing to give you their advice, just like they do with breast cancer 'cures', an emotive issue is best kept to yourself for your own emotional survival. 
I am running a personal survey just to see if there are other women within this network who are in the same boat as me. Does anyone else feel a little left out when sitting in a seminar and not to be included in the discussions? I tell ya, there is a real sense of alienation, but culturally we are told to, 'just get over it', which is fine and life for me has been fulfilling in spite of it all.
My GP doesn't know of another single patient like me which isn't very encouraging in finding my tribe, my mother always said I am different when all you want to do is be like everyone else. So please step forward if you are like me or if you know someone who has a similar story. 
I feel it is a subject that needs discussion and inclusion because in society we, the childless women are 1 in 5, by choice or by circumstance.
