How important will biomimetics be for future researches regarding cancer?

I have read that biomimetics are gainig popularity among reaserchers because nature provides solutions to issues that our society faces. In particular, I have seen many articles that describe how biomimetics and other fields of science, like nanotechnology for example, are interesting approaches for finding cures for cancer. However, most of the experiments that have been made are too expensive for considering them as actual options for curing cancer. I would like to know if this field will actually be useful or if other approaches must be made.
