The Surgeon

Not a day goes by without a new story about the environment. Although we often consider the environment on a global scale, cells in our body also have to contend with environmental factors. New studies from a team of researchers from the Research Institute of the MUHC and McGill University show that the environment surrounding breast cancer cells plays a crucial role in determining whether tumor cells grow and migrate or whether they fade away. Their study is the first to identify the genes behind this environmental control and correlate them with patient outcome. Their findings are published in this week’s issue of Nature Medicine.

A connection between vitamin D level and the risk of developing breast cancer has been implicated for a long time, but its clinical relevance had not yet been proven.

Before breast cancer surgery, a preoperative magnetic resonance imagining (MRI) scan should be standard to determine tumor staging, researchers told the 6th European Breast Cancer Conference (EBCC) in Berlin, Germany today.

Triple-negative breast cancers are a heterogeneous group and may not always be associated with lymph node spread, a new study shows.

The study of 145 triple negative breast cancers (i.e, cancer which is estrogen receptor-negative, progesterone receptor-negative and HER2-negative) in 128 women found that about 23% were moderate or low-grade lesions, said Cecilia Mercado, MD, of New York University School of Medicine, and an author of the study.

Choline, an essential nutrient found in foods such as eggs, is associated with a 24 percent reduced risk of breast cancer, according to a study supported by a grant from the U.S. National Institutes of Health (NIH), to be published in The FASEB Journal’s print issue in June.(1) This study adds to the growing body of evidence that links egg consumption to a decreased risk of breast cancer.
