I'd speculate that is because what is being fought is the tumerous growth and not the cause. Chemotherapy, radiation and surgically removing tumors is an attempt at fixing the symptom. The cause for the tumor is (probably) at molecular level, which we can't properly manipulate.
Some [1] even suggest it might be a """computational""" problem, as the cell loses information about what it's supposed to do. This encompasses not only "classical" information in the DNA base pairs but there is also research going into quantum information being stored in DNA.
