"I have started updating this section"

Soft Tissue Tumour is a complex subject and reporting a case can sometimes be a difficult and perplexing task.

As I continue to update this site a series of infographics and gifs will be created and distributed in various social media platforms and blogs.

In each topic an attempt will be made to include more images, diagrams and links to recent articles.

All suggestions and criticisms are welcome to ensure that the site is formatted to suit your needs.
