Re-post from Relationships: Frequent lurker, occasional poster here. I'll try and keep this brief but I'm 28 years old, married for 3 years in May. My DH and I have started talking about kids and I'm curious what the rest of you might do in this situation. My mom comes from a family of 5 girls and two of my aunts have had breast cancer in their 50's (making the time I should begin annual mammograms my 40's).
Given that your aunts likely had breast CA post-menopause, your risk is lower than if they developed it in their 20's or 30's. It's also possible that there is no "family tendency" but rather just the unlucky odds of 2 of 5 sisters ending up the "one in eight". My mother is one of 7 sisters; two have had breast CA post-menopausally. One was DCIS (which some don't even consider really CA) and the other has an estrogen sensitive CA. After the second dx, they underwent genetic testing and were found to be neg. which means I likely don't carry the genetic predisposition.
Research shows women who have babies before age 30 reduce their risk of breast cancer.
Do you know the absolute difference? The number of women/1000 who were spared breast CA because they had children before 30? Do you realize that 30 isn't a line in the sand; that the risk is lower for a teenage mom than it is for a woman who squeaks in the week before she turns 30?
Research also shows that breastfeeding for 18+ months will reduce the risk. Are you on board with that? And that abstaining from alcohol will as well. Diet and weight play into this as well. But the bottom line is, the risk doesn't matter as much as your personal incidence wihich is either 0% or 100%.
The women in my family have a history of struggling to conceive. One aunt (one that had breast cancer) never did, my parents were on the adoption list when they had me (after 5 years of trying) and another aunt had one child after many miscarriages.
Their reproductive hx has no bearing on yours. In fact women who experience routine early pregnancy losses are at a reduced risk, according to some researchers, because the estrogen levels are often lower than normal.
I realize there are no guarantees in life but if you were me, with this family history and my age, would you TTC sooner rather than later? Financially we would certainly have to re-structure but we are by no means struggling (decent house, no credit card debt, one, manageable car payment). I'd love to know the thoughts of complete and total strangers :)
Have the baby when you are ready. In the meantime, talk to your doc about testing. If your aunts were neg, likely it's not a familial trait and your risk would be more in line with someone without a family hx with your individual life style risks.
