Cancer is a disease of the genome. Today scientists know the enemy much better than before and know that behind a seemingly identical tumor in the lung - colon, pancreas, brain - two patients hide two potentially very different problems. The many genetic pathways that lead to a cell escaping from the iron biological program that controls its growth and division to become cancerous, though not infinite, are enormous.

In recent years, thanks to the routine sequencing of tumor biopsies, patients have been able to benefit from increased customization in treatment: particularly effective drugs against a type of tumor or chemo cocktail whose quotient between side effects and months of life caught up in cancer only makes sense in very specific cases.
