Google’s new AI System More Effective than Humans to Detect Lung Cancer

WASHINGTON – Scientists at Google have claimed that an Artificial Intelligence model developed by them is more effective than human experts in detecting the lung cancer. The AI-based system uses Deep Learning to detect malignant lung nodules on LDCT (low-dose chest computed tomography) scans. This would help to ensure the early diagnosis of lung cancer and hence, it will be possible to treat the disease in its earlier stage. An automated image evaluation system would help to enhance the accuracy in the early diagnosis of the deadly disease. While comparing the results with that of radiologists, it was found that the deep-learning based system works better than those radiologists.

Deep-learning technique uses 3D images. But radiologists carry out the diagnosis of lungs by detecting thousands of 2D images. Hence, it makes the whole process easier to detect any tumor with the help of 3D images.

A research assistant professor at Northwestern University in the United States, Mozziyar Etemadi, shared, “AI in 3D can be much more sensitive in its ability to detect early lung cancer than the human eye looking at 2D images. This is technically ‘4D’ because it is not only looking at one CT scan, but two over time. In order to build the AI to view the CTs in this way, you require an enormous computer system of Google-scale. The concept is novel but the actual engineering of it is also novel because of the scale.”

The research highlights the importance of AI-based technology, as it would make the entire screening process a lot easier if executed well. Hence, by early detection of lung cancer, it will be possible to reduce the mortality rate as lung cancer contributes to the highest number of deaths.

In the Deep-learning technology, both primary CT scan as well as prior CT scan results are taken into consideration. This makes it feasible to predict lung-cancer malignancy risk and hence detect the lung cancer in its earlier stage. The new AI-based system has been tested for over 6,000 de-identified CT scan sets in order to study its accuracy. And, it was found that this system helps to spot minuscule malignant nodules easily.

A sea of confusing technical terms and threats surround people today. Many feel lost, unsure of how to protect themselves online. A distinguished cybersecurity and technology expert, Dr. Dave Chatterjee is teaching people how. He has practiced information technology management since 2001. In this field, which often bewilders outsiders, he combines academic knowledge with practical insights.

About Dr. Dave Chatterjee

The tech figure authored “Cybersecurity Readiness: A Holistic and High-Performance Approach,” which Sage published and readers praise for its thorough and accessible take on cybersecurity preparation.

Additionally, respected publications like USA Today, The Wall Street Journal, and the Massachusetts Institute of Technology (MIT) Sloan Management Review have recognized his work.

“Communicating complex cybersecurity concepts clearly and effectively is essential,” Dr. Dave Chatterjee explains. “I aim to connect technical know-how with practical understanding, making sure important cybersecurity messages reach and impact all stakeholders, from executives to information technology (IT) staff.”

Dr. Dave Chatterjee has received numerous accolades throughout his career. These include the Outstanding Executive Master of Business Administration Professor of the Year award. He has also been named a University of Georgia (UGA) Outstanding Teaching Faculty Honoree.

Before the pandemic, Dr. Dave Chatterjee launched his Technology Roundtable. It features distinguished business leaders, award-winning chief information officers, and other renowned thought leaders. The roundtable covered topics such as blockchain, artificial intelligence, data quality, and cybersecurity.

Aside from his professional pursuits, he is also passionate about youth development. He also engages in science, technology, engineering and mathematics (STEM) initiatives, offering professional development workshops to K-12 students on topics ranging from making the most of collegiate experiences to safe and responsible use of technology. He also provides summer research opportunities for outstanding high school students, mentoring the next generation of cybersecurity professionals.

Decoding Cybersecurity for All

Dr. Dave Chatterjee believes effective cybersecurity involves people as much as technology. He stresses creating an organization’s security-aware culture, starting with clear, straightforward communication.

“Cybersecurity affects every part of an organization,” Dr. Dave Chatterjee states. “We create a shared sense of responsibility and preparedness by explaining complex ideas in relatable ways.”

This philosophy is evident in his roles, including his position as an adjunct associate professor at Duke University and his past work as a professor at The University of Georgia’s Terry College of Business. His skill in explaining technical concepts has made him a popular speaker and advisor across many industries.

The Power of Clear Communication in Cybersecurity

Clear communication in cybersecurity is non-negotiable. As cyber threats become more complex, explaining security concepts clearly and concisely helps organizations better protect themselves.

“Clear communication forms the foundation of a strong cybersecurity strategy,” Dr. Dave Chatterjee emphasizes. “It allows cybersecurity professionals to work with other departments, identify and reduce potential risks, respond well to incidents, and follow regulations and standards.”

This matters especially now, as cybersecurity has become a top priority for company boards. With experts expecting global cybercrime costs to reach $10.5 trillion by 2025, clear explanations of cyber risks and protection strategies help leaders make informed decisions.

Bridging Technology and Human Understanding

Dr. Dave Chatterjee does more than explain technical ideas. He promotes a better grasp of how people factor into cybersecurity, knowing that even the best security systems can fail due to human error or lack of awareness.

His Cybersecurity Readiness Podcast Series has over 70 episodes and listeners in 105 countries. It offers thought-provoking, jargon-free discussions on improving cybersecurity. These discussions cover strategies for individuals, organizations, and nations. This effort shows his advocacy for making cybersecurity knowledge available worldwide.

“The podcast series creates a community where experts, leaders, and practitioners discuss cybersecurity challenges and opportunities,” he notes. “These conversations help build a more informed and resilient digital ecosystem.”

Making Cybersecurity Less Intimidating

With new technologies like artificial intelligence and quantum computing bringing new challenges and possibilities to cybersecurity, concise communication becomes even more critical.

The tech professional continues to adapt his work in this area. A recent USA Today article, “Dave Chatterjee Drops the Cybersecurity Jargon, Encouraging Proactiveness Rather than Reactiveness,” highlights his ongoing effort to make cybersecurity accessible and actionable for everyone.

“The future of cybersecurity depends on our ability to communicate well across all levels of society,” he concludes. “Promoting a shared understanding of cyber risks and best practices creates a more resilient digital world for everyone.”

The battle for digital security requires more than just advanced technology. It demands clear communication. Dr. Dave Chatterjee’s talent for translating cybersecurity concepts into accessible language turns technical knowledge into practical action.

Undeniably, Dr. Dave Chatterjee’s gift for clarity will remain invaluable, helping create a more secure digital future for everyone.
