# Re‐interpreting tumour behaviour and the tumour microenvironment as normal responses to tissue disorganisation

## TL;DR

The paper suggests that tumors and their environment behave like wounds due to disrupted tissue structure, not because of abnormal biology.

## Contribution

It proposes a new perspective that tumor features are normal wound-healing responses to tissue disorganization.

## Key findings

- Tumors resemble wounds due to disrupted tissue structure.
- Features like epithelial–mesenchymal transition and cancer-associated fibroblasts are normal responses to tissue disorganization.

## Abstract

Much of tumour cell biology and the tumour microenvironment may be normal wound‐healing responses as a consequence of the disruption of tissue structure. This is why tumours resemble wounds, and many features of the tumour microenvironment, such as the epithelial–mesenchymal transition, cancer‐associated fibroblasts, and inflammatory infiltrates, may largely be normal responses to abnormal tissue structure, not an exploitation of wound‐healing biology. © 2023 The Author.
