Still Don't Completely Understand

We don't know which specific combinations of environmental factors on the outside of a person's body combines with an individual's genetic background on the inside to cause cancer. We don't know why two persons can have very similar environmental exposures, yet one gets cancer and the other does not. A number of individual factors are involved, and there are complex relationships among them. Hopefully, the technology that is empowering an era of personalized medicine will also help oncologists to address these and other unanswered questions about cancer.
