And although breast density generally declines with age, up to a third of women retain dense breast tissue for years after menopause.

It's also older women with dense tissue.

Two thirds of women in their 40s have dense breast tissue, which is why mammography doesn't work as well in them.

Both tumors and dense breast tissue appear white on a mammogram, and the X ray often can't distinguish between the two.

Yes, the issue was about breast tissue engineering.

Mammography relies on differences in the appearance of the tumor from the background tissue, and we've seen that those differences can be obscured in a dense breast.

If the breast is less than 25 percent dense, that's called fatty replaced.

But imagine how difficult it would be to find that tumor in this dense breast.

Radiologists classify breast density into four categories based on the appearance of the tissue on a mammogram.

Dense

Northern Tissue.

But it's still extremely dense. It's still extremely dense.

You can see, on the right, a mammogram showing a faint tumor, the edges of which are blurred by the dense tissue.

And Copenhagen, although it's a dense city, is not dense compared with the really dense cities.

And dense gardens.

And dense gardens,

and dense orchards,

So, tissue design.

So what was yay dense is now not so dense anymore.

and dense tree'd gardens,

Dense bushes concealed him.

You sure are dense

Yes, breast cancer.

Give Tom a tissue.

So now that we knew that this technology could find three times more tumors in a dense breast, we had to solve one very important problem.

and gardens dense with foliage?

And gardens dense and luxuriant.

and gardens dense with foliage.

And gardens of dense shrubbery

They're probably less cell dense.

The next category is scattered fibroglandular densities, followed by heterogeneously dense and extremely dense.

Sorrow filled his breast.

Give a tissue to Tom.

Living tissue over metal endoskeleton.

It's then called a tissue.

And her mammogram showed an area of very dense tissue, but her MBI showed an area of worrisome uptake, which we can also see on a color image.

And gardens, dense with many trees,

A dense hedge surrounded the garden.

I'm breast feeding my baby.

I work on breast cancer.

She died of breast cancer.

Molecular Breast Imaging, or MBl.

The digital mammogram was read as normal and shows lots of dense tissue, but the MBI shows an area of intense uptake, which correlated with a two centimeter tumor.

Muscle tissue consists of innumerable cells.

No, not that kind of tissue.
