100 Influential Women in Oncology: Key Opinion Leaders to Follow on Social Media in 2025

Starting on August 26, 2023, in honor of Women’s Equality Day in the United States, which commemorates the 1920 law granting women the right to vote, OncoDaily launched an initiative to spotlight 100 remarkable female leaders in oncology worldwide. Each week, 10 inspiring women were introduced, culminating in the full list and an updated edition in 2024.

Continuing this tradition, we are proud to present the 2025 list of 100 Influential Women in Oncology to Follow on Social Media.

While there are countless exceptional women leaders in oncology who deserve recognition, we acknowledge that we couldn’t feature everyone. This initiative is ongoing, and we look forward to your nominations for 2026. We’ll be sharing the submission link soon.

Here are the second 10 of 100 Influential Women in Oncology to follow in 2025:
