Professor Chun Ju Chang, a prominent cancer biologist with experience at major research institutions in the United States and Taiwan, is highlighting the urgent need for enhanced mentorship and education in cancer research. She argues that the future of cancer science depends not only on funding and equipment but on investing time and attention in the people conducting the research. This call comes as the World Health Organization projects global cancer cases will reach 28 million annually by 2040, increasing pressure on research systems worldwide.
Chang points to studies showing that many early-career scientists leave research within their first decade due to burnout, lack of guidance, and unclear career paths. Research published in Nature indicates that scientists with strong mentors are twice as likely to publish high-impact studies and remain in research long-term. Despite this evidence, structured mentorship remains inconsistent across institutions. "I've watched talented students lose confidence because no one slowed down to explain the process," Chang said, noting that often just one person taking time to walk through data can make a significant difference.
With a career spanning UCLA, the University of Texas MD Anderson Cancer Center, Roswell Park Comprehensive Cancer Center, and currently China Medical University in Taiwan, Chang believes strong mentorship develops more than technical skills—it builds judgment, resilience, and confidence. "Experiments fail all the time," she explained. "What matters is learning how to resolve the issues without panic. That mindset comes from guidance, not textbooks."
Mentorship also addresses diversity and inclusion challenges in science. According to UNESCO, less than 30% of researchers worldwide are women, with even lower representation in senior roles. Chang views mentorship as an effective tool for change, stating, "Talent exists everywhere. What's missing is consistent support. When people feel seen and guided, they stay and contribute." Well-mentored teams produce clearer data, fewer errors, and stronger collaboration, directly affecting the quality and speed of cancer discovery.
Rather than focusing solely on policy reform, Chang emphasizes individual action. "You don't need a formal title to mentor someone," she said. "You just need patience and a willingness to listen." She encourages practical steps such as encouraging curiosity in students, sharing knowledge openly—especially lessons from mistakes—offering informal guidance to early-career researchers, promoting inclusive environments, and supporting science education through various programs. "Small actions add up," Chang noted. "The next breakthrough may depend on a student who almost gave up but didn't because someone helped them through a hard moment."
As cancer research grows more complex, Chang believes mentorship will become increasingly vital. "The science will keep changing," she concluded. "The need for good guidance will not. If we get that right, everything else becomes possible."
