A. New Hope For Breast Cancer Management

Narrator: This is Science Today. Improved magnetic resonance imaging, or MRI, may lead to better breast cancer management. Dr. Laura Esserman, director of the Breast Care Center at the University of California, San Francisco, says MRI can provide valuable information to both patients and their doctors.

Esserman: I see it as perhaps having a role in taking women who have had something that looks abnormal on mammography and doing an MR at that point to keep them from having to have a biopsy. I see it also able to identify when therapy's aren't working, you can change direction. And maybe help introduce all the novel therapeutics that are in development.

Narrator: MRI was also more precise in determining the boundaries of tumor tissue. This can help preserve healthy tissue more reliably.

Esserman: I think that MRI hold tremendous promise but it is not yet ready to be used widely because there's still a lot of work to be done. It's something that I hope within two years will be out in a more general way.

Narrator: For Science Today, I'm Larissa Branin.
