Breast cancer is the most prevalent type of cancer among women, with approximately 13,000 new cases diagnosed each year in Australia. Our Breast Biology and Cancer Unit are researching the basis of the cellular and molecular mechanisms that underpin this high incidence of breast cancer. We use a variety of mouse models, together with human breast tissue, to study how key risk factors, including menstrual cycling and breast density, lead to increased susceptibility of the mammary gland to cancer. We focus on how these risk factors affect the ability of the immune system to protect this unique tissue against carcinogens and other cancer initiating factors. The overarching objective of our research is to provide therapies that reduce a woman’s lifetime risk of developing breast cancer.
In addition to studies on breast cancer susceptibility, we also conduct mastitis research. Mastitis is a common inflammatory disease in lactating women that causes pain, fever, low milk supply and leads many to cease breastfeeding. This research explores the cellular mechanisms that lead to inflammation, and investigates potential therapies to quickly and effectively stop the symptoms of mastitis.
The Breast Biology and Cancer Unit was established at the BHI in 2011 as part of the collaborative links established at The Queen Elizabeth Hospital (TQEH).
We welcome enquiries from students about potential Honours and PhD research projects.

Macrophages are cells with diverse roles in immune responses against invading pathogens and cancer, and tissue development and homeostasis. This project will explore the function of macrophages in establishing breast density, which is a major risk factor for breast cancer.
The ovarian hormones estrogen and progesterone regulate a variety of cellular pathways in the breast that affect cancer risk. This project will investigate how these hormones regulate macrophages using tissue cultures and histological analysis of breast tissue.
Recent studies indicate that antibiotics have limited efficacy in both treating and preventing mastitis. This project will investigate the underlying cause of mastitis using a combination of animal models and cell culture.
