Mortality from breast cancer has improved significantly in the last 40 years. However, there remains certain subgroups of patients with breast cancer who have worse survival. Dr. Lim’s research program focuses on these subgroups to better understand the reasons for their poorer outcomes. Lobular breast cancer is the second most common subtype of breast cancer, and long-term survival is worse compared with invasive ductal carcinoma. He’s been funded by the Terry Fox Research Institute to study treatment and outcomes in patients with lobular breast cancer, recruiting from multiple hospital centers across Canada.

As breast cancer survival improves, research is shifting towards improving quality of life for breast cancer survivors and cautiously de-escalating breast cancer treatment. He studies patient-reported outcomes and the experiences of patients receiving treatment, including ambulatory surgery at Women’s College Hospital. He also studies specific aspects of surgical decision-making including contralateral prophylactic mastectomy, and the impact of neoadjuvant therapy on treatment. As we move towards an equitable health care system, his research team is actively studying the racial, ethnic, gender and social disparities that underlie differences in breast cancer outcomes.
