Sarcomas can easily shove aside normal tissue without causing any symptoms. Discomfort may occur only once these tumors grow large enough to press against the nerves or muscles.
A bone sarcoma may cause pain and/or swelling in an arm or leg, the trunk, the pelvis, or the back. This area may sometimes feel warm to the touch. Other symptoms include a limited range of motion in a joint, a fever for no known reason or a bone that breaks from no apparent outward injury.
A soft issue sarcoma may cause pain or a feeling of fullness or difficulty breathing.
These symptoms are very general and may also be signs of other medical conditions.
Patients are naturally concerned when finding a lump in the arm, leg, or trunk of the body yet it is important to remember that most lumps are not sarcomas. A lipoma, for example, is a very common benign growth—made of fat cells, not cancer cells. It is important to have any lump or swelling immediately evaluated by a physician.
