Clinical Teams

My junior kindergarten teacher asked me, 'What do you want to be when you grow up?' I said: 'A doctor!'

Growing up in Iran, Sayeh Lavasani, M.D. always knew she wanted to be a doctor, like so many members of her family (“Being a physician was natural to me,” she says.)
A top student, she excelled at Iran University of Medical Sciences in Tehran, then moved to Ontario, Canada to continue her training at University of Toronto, Queen’s University in Kingston, and McMaster University.
Dr. Lavasani specializes in treating HER2-positive breast cancer and has done extensive research in the field, publishing numerous papers and conducting multiple clinical trials.
Dr. Lavasani is excited about the many new treatment options available for HER2-positive breast cancer. Enabling her patients to defeat cancer and live healthy lives is something she finds especially rewarding. She feels honored to be part of the City of Hope team where “I can offer my patients the novel treatments and a chance to enroll in clinical trials which can help both patients and science.'
