Testing

There are many types of tests used in breast cancer care. Breast cancer tests identify the type and scope of breast cancer so you can access the right treatments at the right time – for you.

Access expert insight into your pathology report, breast cancer stages, and scans, blood, and tumor-based tests. And get the facts about tumor biomarker tests and genetic testing for inherited mutations.

ESR1 testing: What you need to know

If you have been diagnosed with estrogen receptor-positive, HER2-negative metastatic breast cancer you may develop an ESR1 mutation after progression on endocrine therapy. ESR1 mutation testing can help you and your healthcare team make decisions about the most effective treatment options for you.

In this video, Eleonora Teplinksy, MD, Head of Breast and Gynecological Medical Oncology at Valley-Mount Sinai Comprehensive Cancer Care, explains more about more about ESR1 testing, who should get tested and when, and how it impacts treatments for metastatic breast cancer.

Personalized medicine for breast cancer: What you need to know

If you’re newly diagnosed with breast cancer, you may be familiar with genetic and genomic testing. These tests hold the key to unlocking personalized medicine, providing important information that helps your doctor to make decisions about the most effective treatment options available to you.

In this video, experts Evelyn Robles-Rodriguez, DNP, APN, AOCN, and Generosa Grana, MD, FACP, guide you through the complex world of genetic and genomic testing, so that you will understand the differences, learn how these tests are used at various stages of breast cancer, and discover how these tests can impact you or your family. Also, you'll gain practical tips to become an advocate and a shared decision-maker in your care.
