Breast Cancer Research Highlights

The American Cancer Society (快猫短视频) helps people with breast cancer in every community.?Our research programs have played a role in many of the prevention, screening, and treatment advances that save lives from breast cancer today. And, we continue to fund research to help save even more lives in the future.

Breast Cancer Continues to Increase

Since the mid 2000s, slight increases in breast cancer incidence rates may be partly due to more women having obesity, fewer children, or their first baby after 30.

New AI Tool Improves the Accuracy of a Breast Cancer Prognosis


The diversity represented by 快猫短视频 CPS-II tumor samples and the long-term data we have from breast cancer patients made this high-impact work possible.

Risk and Prevention Studies

Testing Diverse Groups Finds New Breast Cancer Genes

Researchers’ analysis of genetic data from diverse ancestral groups uncovered new genes implicated in the development of breast cancer.

Black Women Need Genetic Testing for Breast Cancer Too

A study including CPS-II/3 survey and blood data finds that both Black and White women need genetic counseling/tests to predict the risk of breast cancer.

Women 65+ May Benefit from Genetic Tests for Breast Cancer Risk

For the first time, researchers estimate the prevalence of pathogenic variants of breast cancer predisposition genes beyond BRCA1/2 in older women over age 65.

The 快猫短视频 Cancer Prevention Studies have played a role in identifying or validating every known common genetic variant for breast, prostate, and pancreatic cancers. We've collaborated with scientists across the United States to analyze large compilations of data. We're helping make discoveries about the genetics of cancer that have the potential to improve screening guidelines, lead to new targeted therapies, and inform follow-up care after cancer treatment."

New Screening Strategies May Help Women with Genetic Risks

Starting yearly MRIs 5 years before yearly mammography may reduce breast cancer death in women with ATM, CHEK2, and PALB2 pathogenic variants.

Housing Assistance May Help Some Women Get Mammograms

快猫短视频 researchers find some women with low income are more likely to get breast cancer screening when they get housing assistance than ones who don’t.

Treatment and Reducing Metastasis Studies

Blood Cells That Clot Wounds May Help Breast Cancer Spread

Mouse studies reveal a feedback loop: Platelets help breast cancer start, then cancer leads to platelets that support metastasis.

Some Natural Killer Cells Aid & Abet Triple-Negative Breast Cancer

An 快猫短视频-funded researcher learns how cells that typically kill infected and diseased cells switch sides in the tumor microenvironment to help TNBC grow.

3D Mini Breast Tumors May Help ID New Cancer Treatments

Researchers grew 3D organoid cultures from mice injected with human tumor cells and tested both with existing and new drugs for hard-to-treat breast cancers.

Featured Breast Cancer Term:?Triple-negative Breast Cancer (TNBC)

A subtype of breast cancer that grows faster and is more likely to spread and recur. It is more common in women younger than age 40, who are Black, or who have a BRCA1 genetic mutation.?

It’s called triple negative because the cancer cells in TNBC don’t have receptors for the hormones estrogen (ER) or progesterone (PR). Plus, TNBC cells make very little or none of the protein called HER2 (human epidermal growth factor). That means all 3 biopsy tests to check for these hormones and the HER2 protein come back "negative."?
