People with early stage soft tissue sarcoma usually do not notice any symptoms. In fact, symptoms of soft tissue sarcoma may not appear until the cancer has grown for some time. The following are common symptoms of soft tissue sarcoma:
A lump on the body, which is usually painless
Stomach pain and vomiting
A full feeling after not eating very much
Blood in the stool (a red or tar-like black stool)
Lack of appetite or weight loss
These symptoms may be the result of soft tissue sarcoma. They may also be symptoms of less serious illnesses. If you have any of these symptoms, see a health care provider right away.
