What makes a woman feminine? Is it the unmistakable curves of her hips, whether big or small, that, try as hard as they may, not even the most seasoned cross-dresser can mimic?
Is it the softness of her skin that no metrosexual can match with all his facial creams and waxing sessions? Or perhaps it's her breasts? They nourish and provide sustenance for her babies.
They soothe little ones by resting their heads on them. The attract potential partners. They're sexy.
But what if you or your partner had to have them removed? For those who don't know, October is breast cancer awareness month.
I have come across many women who have survived this illness. And I also knew a few who didn't.
While breasts may symbolise the very essence of femininity, it's by no means the only quality worth mentioning.
There are remarkable women without a one or maybe both breasts walking among us. The are changing the world, and making noticeable differences. They have been made stronger than we could ever imagine.
They are everyday people, with families and jobs and bonds to pay.
But some of them go beyond just living for themselves. I met a woman recently who had both of her breasts removed after she was diagnosed with cancer.
Instead of crawling underneath a rock to fade away into obscurity, she is a rock of strength, and her story inspires other women.
Maybe it's because of her support system. She has a loving husband and daughters and they are a tightly knit unit. On the surface, she seems like any regular woman.
But when you realise what she has accomplished in a short time, despite what she's been through, you can't help but be amazed.
This brings to mind another issue: Why must we wait to be diagnosed before we go out and make a difference?
Why can we, as healthy-breasted, ordinary women, not stand with our sisters who have lost theirs, to bring about awareness and change in attitudes and perceptions?
Why do we wait until someone comes around collecting money for the cause or invites us to fund-raisers, but never initiate anything ourselves?
Do yourselves a favour: Next time you have a look in the mirror, appreciate your breasts, whether they are lopsided, tiny, enormous or plain quirky.
Then go out there and make a difference.
