Abstract

Recently at least two papers1,2have appeared that look at cancer from an evolutionary perspective. That cancer has a negative effect on fitness needs no argument. However, cancer origination is not an isolated process, but the potential for it is linked in diverse ways to other genetically determined developmental events, complicating the way selection acts on it, and through it on the evolution of development. The two papers take a totally different line. Kavanagh argues that anti‐cancer selection has led to developmental constraints. Leroi et al. argue that cancer is a side‐effect of recent evolutionary changes that usually will disappear over time through anti‐cancer selection. Here we place the papers in a wider perspective, and in so doing discuss various alternative developmental links cancer may have together with their evolutionary implications.

## Abstract There are few biomarkers that have been developed which have proven clinical utility for the detection and prognosis of cancer. Cancer is diagnosed today, in large part, by examining cells under the microscope and determining the shape and texture of the nucleus. The molecular underpinn
