The ultimate goal of precision oncology is to provide the right cancer drug to the right patient at the right time. However, cancer is difficult to treat in part because it isn’t just one disease – every cancer is unique. Even if two people have the same type of cancer in the same organ, their tumors are different.
And other important variables make precision cancer treatment challenging.
There is the sheer number of cancer drugs on the market. In the past four years alone, more than 250 oncology drugs have been approved, bringing the total number to more than 600.
