how old

Ladies,
we have occasionally shouted at a curiousity question, so here's mine.
How old were you when first dx and how old when the mets were dx. The reason for asking is I have been informally asking women in their 60's & 70's how common B/C was when they were in their 30's & 40's compared to how common it is now. Better diagnosing or perhaps environmental??????? Between industrial pollution and hormones/antibiotics in farm animals,,,,,,you just gotta wonder if we are not the first generation to be battling something that is completely out of our control?
Not meant to be a political discussion, just more of a random thought.
