Yes, there is a link between endometrial cancer (cancer of the lining of the uterus) and breast cancer. Both cancers share common risk factors, such as obesity, hormone replacement therapy (HRT), and a family history of these cancers. Additionally, some genetic mutations, such as those in the BRCA1 and BRCA2 genes, increase the risk of both breast and endometrial cancers. At the Texas Breast Center, we provide comprehensive genetic testing and counseling to assess your risk for multiple types of cancer.
