BANGALORE, INDIA - Diagnosing cancer generally requires two modalities: radiology, which helps in the staging of cancer and includes looking at scans like X-Rays, computed tomography or magnetic resonance imaging scans,1 and pathology, which helps in the grading of cancer.2
This is done by taking a piece of suspected cancer tissue and looking at it under a microscope. The prognosis of cancer is determined by both. On the one hand, the staging of cancer represents the extent of the spread of cancer tissues in different body parts beyond the source of origin - called ‘metastasis.’ On the other hand, grading of cancer represents the aggressiveness of the cancer, which is also known as the type of cancer. Different subtypes of cancer have varying grading, and thus differing levels of aggressiveness.
Pathology, for the most part, still relies on observing cancer tissue stained with different dyes under a microscope, whereas radiology now mostly relies on a digital version of scans.3 Over the past couple of years, it has been observed that digital pathology has gained momentum in adoption by pathologists around the world.4 The Covid-19 pandemic has accelerated this adoption, as the transition to digital pathology is now emerging more as a requirement than as a preference. As one example of many cases of use of digital pathology, it is helping with remote reporting in areas that lack specialist pathologists.5
Despite the benefits of digital pathology, as with any new technology transition it must first overcome some challenges. There are many issues impacting the speed of its adoption, especially in developing countries:
