I have been working at the Netherlands Cancer Institute as a pathologist since August 2014. As a pathologist, I analyze tumors from cancer patients through a microscope. Tumors may look similar, but the genetic changes vary greatly between patients.
In other words: no two tumors are the same in terms of DNA. This diversity leads to differences between treatment results and, as a result, survival rates between patients. At the Netherlands Cancer Institute, we work hard to make sure that all individual patients receive a personalized treatment based on the genetic changes found in their tumor cells.
