A longstanding question in cancer: why do tumors only form in certain locations in the body? In our new @nature paper (nature.com/articles/s4158…), we define anatomic position of the cell as a mechanism for this.

These DNA alterations only cause cancer if they synergize with the intrinsic positional gene program present in these different anatomic sites.
