A New Test Determines Your Breast Size: Find Out How Big Your Boobs Will Get!

Buying bras is already annoying to begin with, but it’s even more of a chore when your breast size is changing–what fits you now may have to get tossed next year when your cup size increases. Luckily for us, though, scientists have narrowed down precisely what genetic factors determine your breast size, so you’ll know what you’re in for later.

Doctors have found seven genetic markers for breast size, and–health bonus!–two of the genetic markers for breast size also can help determine a gal’s risk for breast cancer later on. Doctors conducted a survey of a little over 16,000 women, comparing their breast size (through their cup and band size of their bras) to their genetic profiles. Everyone has their own unique breast size, shape, and structure, and before we go any further, we want to reiterate–your boobs are probably awesome. No, seriously!

It’s been known for a while that breast size generally runs in families–if most of your female relatives are D cups, don’t expect to be inducted into the Itty Bitty Titty Committee–this is the first study that actually looks at which genes are behind breast size specifically, and takes a look at how differences in breast size, shape, and structure can affect your health.

There have been a few studies somewhat recently that linked large breast size in lean women to a heightened breast cancer risk, but this study doesn’t necessarily support or refute those claims. In fact, the makers said the research is way too preliminary to be taken too seriously, and that one of the biggest factors in breast cancer risk isn’t breast size, but actually obesity. Additionally, breast density is more of a likely factor than breast size in determining breast cancer risk, though docs and scientists aren’t really sure why just yet.

The study does, however, make it easier to pinpoint variations in breast size and structure to make comparisons and studies of breast size in relation to breast cancer more accurate later on–and since the risk increases as we get older, maybe by the time we’re really at risk, there will be a ton of more ways to prevent and treat it. Rad thought, right?

And bonus: the study may make trips to the lingerie shop a little easier since you can buy ahead of your current breast size if you suspect you’ll grow some more!

    My breast started growing in 4th grade by the time my period started in 7th grade I was in 36 C. Since all women in my family are C cup or less I figured they were done. By 17 I was 36 D and at 21 38DD. Then my son was born and I cried in the fitting room getting a nursing bra in 38 G. Everyone swore they would go down when I was done breast feeding, they were wrong. Then I was told they don’t grow after 28, I lost 10 pounds that year and still went up to 38H. I’m about to deliver my second child and praying the girls don’t grow again. Its too hard to find bras now and so freaking expensive. Be happy you can go in any store and find a good fitting bra for $20, I know 2 stores thay carry my size and its hit or miss then $50-$65 per bra.
