The Pan-Cancer Analysis of Whole Genomes Consortium has analyzed the genetic code of 2,658 different cancers and produced a picture of each. Creating a perfect picture of each cancer will now allow doctors to better understand how they work and enable them to diversify treatment to each patient. Dr. Lincoln Stein from the Ontario Institute for Cancer Research commented that previously doctors would only have a chance of knowing why a patient’s cells became cancerous in two thirds of cases. Scientists from 37 countries have results published in 22 scientific papers to describe the thousands of possible mutations that may occur. The findings led to the discovery that most cancers thrive off four or five main mutations, creating a possible weak spot for doctors to target.
