So we know that the sensitivity of MRI is exquisite for the detection of breast cancer.

The best way for surveillance right now is to get a mammogram at one point and an MRI six months later and to keep that up.

One is recently there's been a new technology called contrast-enhanced mammography.

We don't know what that's going to be like for women with genetic susceptibility to breast cancer, but the preliminary data from a large study that just came out of the UK seems to suggest that it's not quite, but pretty close, or that it's pretty close to MRI.

The thing about it is MRI has no radiation exposure, and of course, mammography has a low level.

MRI does not replace mammography in most people, but there are some mutations that have exquisitely sensitive mutations to radiation.

And in those women, sometimes we don't use mammography, but generally it's mammography does not.
Yeah, thank you for bringing that up because I think age often is a question, right? I think the standard for somebody who is of average risk, is it still 40?

And if you have a family member, first degree relative, you should start five to 10 years earlier than the age at their diagnosis.
And screening, as you've said, screening is not one size fits all, right? So we talked a bit through mammography and MRI, but ultrasound is also identified.
Did we talk about that yet? Or can you share a little bit around ultrasound? No, ultrasound is

First of all, in women... who don't have genetic mutations and have dense breasts, we know that ultrasound can double the number of cancers that are found.

And it doesn't require an injection like MRI does, and it doesn't use ionizing radiation like mammography or contrast-enhanced mammography does.
