Seminars in Oncology is a major Cancer Biology and Oncology seminar series at the Dana-Farber Cancer Institute, in Boston, MA. For over 20 years, local, national and internationally-recognized Oncologists have presented a rich diversity of prevalent topics in cancer research and care. These Seminars are especially important for our medical students, fellows, and trainees in their development as future Oncologists. Prior to COVID-19, these Seminars were largely and regularly attended by faculty and students throughout the Longwood Medical area, and webcast live for others in surrounding Institutions. Until it is safe to return to in-person attendance, these Seminars will be held weekly via zoom on Thursdays (beginning on April 22nd).
