# Breast Metastasis: An Unusual Cause of Malignant Breast Lesion

## TL;DR

This paper highlights that breast lesions can rarely be caused by cancer spreading from other parts of the body.

## Contribution

It emphasizes the importance of considering metastasis in patients with a history of cancer when diagnosing breast lesions.

## Key findings

- Intra-mammary metastasis from extramammary cancer is a rare but possible cause of breast lesions.
- Patients with a prior oncological history should be evaluated for metastasis in new breast lesions.

## Abstract

Teaching point: Although rare, an intra-mammary metastasis from extramammary cancer should be considered in a patient with an oncological history.
