Soft tissue sarcoma cancer
In their early stages, soft tissue sarcomas do not usually cause symptoms. As sarcomas can grow anywhere in the body, the symptoms will depend on where the cancer is. The main symptoms can include:
a lump that's painless at first
a lump increasing in size
pain or soreness as the lump grows and presses against nerves and muscles
You should see your doctor if you have an unexplained lump. Many people get lumps and bumps and most of them will not be cancer. But it's best to get it checked.
A lump is more likely to be a sarcoma if it:
is big (for example, more than 5 cm across) or getting bigger
is deep in the body tissues
is painful
occurs when you are older
has come back after previous surgery to remove sarcoma
It's possible to have other symptoms from sarcoma. But it's difficult to list all of these because it would depend on where the sarcoma is in your body. See your doctor if you notice anything that isn’t normal for you.

There are some things you can do to get the most out of your GP appointment if you have symptoms of a soft tissue sarcoma.
Your GP should arrange for you to have a test or to see a specialist if you have symptoms that could be due to a soft tissue sarcoma.
You have a number of tests to check for soft tissue sarcoma. The tests you might have include an ultrasound scan and taking a sample of tissue called a biopsy.
We don't know what causes most soft tissue sarcomas. But some factors may increase your risk of developing it. Having any of these risk factors does not mean that you will develop cancer.
Soft tissue sarcomas are cancers that develop in the supporting tissues of the body. These include tissues such as the muscle, nerves, fat and blood vessels.
