Tests for soft tissue sarcoma

You might have one or more of the following tests to diagnose and stage soft tissue sarcoma, or to check how well your treatment is working.

You usually start by seeing your GP if you have symptoms. They examine you and might refer you for tests. Most people have an ultrasound scan and/or an MRI.

Ultrasound scan for soft tissue sarcomas

Ultrasound scans use high frequency sound waves to create a picture of a part of the body.

Blood tests

Core needle biopsy for soft tissue sarcoma

A core needle biopsy is a procedure where a doctor takes a sample of cells from a suspicious lump or area of tissue.

An MRI scan creates pictures using magnetism and radio waves. 

Surgical biopsy for soft tissue sarcoma

A surgical biopsy is a procedure where a doctor takes a tissue sample from the lump or removes the whole lump.

Tests that look at the chromosomes and genes in the cancer cells are called cytogenetic tests. These tests check if there are any genetic changes (mutations) in the cells.
