Signs of sarcoma vary from person to person. Since sarcoma does not usually present symptoms in the early stages, only about half of soft tissue sarcomas are found early before they spread.
The location of a sarcoma has a lot to do with the symptoms. For instance, if it starts:
- On the arms or legs, a lump that grows over a period of weeks or months may be noticed. It may hurt, but it usually does not.
- In the retroperitoneum (the back wall inside the abdomen), it may cause problems that have painful symptoms. Tumors may cause blockage or bleeding of the stomach or bowels. They may even grow large enough for the tumor to be felt in the abdomen.
If you have any of the following problems, talk to your doctor:
- A new lump or a lump that is growing anywhere on your body
- Abdominal pain that is getting worse
- Blood in your stool or vomit
- Black, tarry stools (this may mean there is internal bleeding)
It is important to note that these symptoms do not always indicate sarcoma. However, it is important to discuss any symptoms with your doctor, since they may also signal other health problems.
