or mammary glands. All they have in that area is what they have in other areas: tissues, lymph nodes, etc.

But they're undeveloped. The same tissues are present in both sexes.

You're standing on that slippery slope that leads to evolution as science.

All mammals feed their young with it.

My wonderful wife used to have business cards that had "Mammal" under her name. She's a freelancer, so she had no particular job title. The cards were a big hit.

Maybe because people live longer? Perhaps in a couple hundred years they will be routinely replaced with silicone fakes at a particular age past childbearing.

Fewer kids. Kids later in life (that seems to matter). Fewer women breastfeeding. And breastfeeding in less regular ways (less volume) for less time.

Earlier puberty.

Even race, although separating out all the other factors--incluing race-based incidence of the known genes related to breast cancer--sometimes leaves "race" with a statistically marginal share of the incidence.

Take a woman who matured at 16 and died at 45 with 5 pregnancies and 3 births, each brood nursed for 9 months. Compare that with an 85-year-old woman who matured at 13 and hit menopause at 48, had two live births and no miscarriages and who didn't breastfeed at all because she wanted to go back to work.

The specific woman I had in mind was the 85-year-old, who's my mother and was diagnosed with breastcancer at age 78.

Fewer kids. Kids later in life. No breastfeeding. Plus she smoked for years--more toxins. (She also worked at a steel mill--additional toxins, although most of them were self-inflicted. In the laundry room she kept trichoroethylene from work and would regularly use to remove stains from clothes.) Statistically she did almost everything possible to predispose herself to breast cancer.

Her twin--one fewer kid, less work-exposure to toxins--developed breast cancer, as well. So her genetics were also probably working against her.

and anecdotal info.. thank you.

I used to work in a drycleaner's.. the fumes were so intense. I only worked there for a few months when I was 17. the guy who owned it died of cancer only in his 40's a few years later.

We used to swim downriver in the sludge from nuclear submarine plant and pfizer chemical plant. Lots of people from my childhood died, went mad, got cancer.

nuclear weapons testing that took place over the decades (in my opinion).

Hit the gym, Jack.

might look better on a young girl but yeah, he's allowed.
