Genomics and bioinformatics as pillars of precision medicine in oncology.

The battle against cancer has advanced tremendously in the last thirty years and the survival rate has doubled. However, it is still difficult to achieve a generalized cure. The challenge is that cancer is not a unique disease; it is about dozens of different manifestations, even within the same tumor location. For systems biology, each solid tumor is a unique system characterized by its cellular heterogeneity, its interaction with the microenvironment in which it grows and develops, and its ability to adapt and modify it. Recent advances in understanding the molecular mechanisms that underlie cancer are transforming the diagnosis and treatment of the disease. In this sense, a growing set of treatments capable of attacking a specific tumor with higher efficiency has been developed, defining a new paradigm: the precision medicine in oncology. Genomics and bioinformatics are two fundamental pillars in this applied field. These technologies generate massive data (Big Data) that require analytical tools and trained personnel for the analysis, integration and transfer of the information to physicians. This presentation describes the concepts of personalized medicine, Big Data, the main advances in genomics and bioinformatics as well as their future perspectives and challenges.
