A team of Google researchers has used a deep-learning algorithm to detect lung cancer accurately from computed scans.

The work demonstrates the potential for Artificial Intelligence (AI) to increase both accuracy and consistency, which could help accelerate adoption of lung cancer screening worldwide.

Lung cancer is the deadliest of all cancers worldwide — more than breast, prostate, and colorectal cancers combined — and it’s the sixth most common cause of death globally, according to the World Health Organization.

“Using advances in 3D volumetric modeling alongside datasets from our partners (including Northwestern University), we’ve made progress in modeling lung cancer prediction as well as laying the groundwork for future clinical testing,” Shravya Shetty, M.S. Technical Lead at Google explained in a blog post late Monday.

Google researchers created a model that can not only generate the overall lung cancer malignancy prediction (viewed in 3D volume) but also identify subtle malignant tissue in the lungs (lung nodules).

In the research, Google AI leveraged 45,856 de-identified chest CT screening cases (some in which cancer was found).

“When using a single CT scan for diagnosis, our model performed on par or better than the six radiologists. We detected five per cent more cancer cases while reducing false-positive exams by more than 11 per cent compared to unassisted radiologists in our study,” said Google.

For an asymptomatic patient with no history of cancer, the AI system reviewed and detected potential lung cancer that had been previously called normal.

These initial results are encouraging, but further studies will assess the impact and utility in clinical practice, said Google.

After announcing a fresh investment of $600 million in expanding its data centre in Oklahoma, Google has now decided to invest $1 billion for 20,000 homes in the Bay Area in San Francisco.

“Today we’re announcing an additional $1 billion investment in housing across the Bay Area. Over the next 10 years, we’ll repurpose at least $750 million of Google’s land, most of which is currently zoned for office or commercial space, as residential housing,” Google Chief Executive Officer Sundar Pichai wrote in a blog-post on Tuesday.

The project is aimed at supporting the development of at least 15,000 new homes at all income levels in the Bay Area, including housing options for middle and low-income families.

“We’ll establish a $250 million investment fund so that we can provide incentives to enable developers to build at least 5,000 affordable housing units across the market,” Pichai said.

In addition to the increased supply of affordable housing, the search engine giant has also announced to give $50 million in grants through Google.org to nonprofits focused on the issues of homelessness and displacement.

“This builds on the $18 million in grants we’ve given to help address homelessness over the last five years, including $3 million we gave to the newly opened SF Navigation Center and $1.5 million to affordable housing for low income veterans and households in Mountain View,” Pichai added.
