Another surprise

Discovered in a Wall Street Journal article about a recent cancer research development —

Researchers studying brain tumors said they have discovered a new biological mechanism that causes normal cells to become cancer cells, a finding that both challenges current treatment strategies and could lead to new approaches against the disease. * * *  

[The discovery] underscores cancer’s complexity. The process appears to operate independently of the so-called driver mutations that fuel cancer. The finding may help explain why treating tumors with drugs targeted at such mutations—a strategy known as precision medicine—is having limited success. While such targeted treatment often dramatically shrinks tumors initially, in most cases, patients eventually relapse.
