'Google search algorithm helps track spread of cancer'
Following the Google's example with search results, the researchers split the sites where the lung cancer spread to into two groups into first and second order.
In first order sites, tumour cells would most likely reach them by travelling directly from the lung. Tumours are more likely to reach second order sites by colonising a first order site and then spreading to the second order location.
Researchers, using this approach, were even able to estimate the average times it takes the cancer to spread to different parts of the body, the report said.
