Bone and soft tissue sarcomas are cancerous regions that can begin in any part of the body. Found in both children and adults, about 60 percent of sarcomas begin in an arm or leg, 30 percent in the abdomen and 10 in the head or neck. Rare in adults – accounting for 1 percent of all adult cancers – sarcoma is most often found in children, representing about 15 percent of all pediatric cancers.
Symptoms of sarcoma often do not appear in the early stages of the cancer. Typical symptoms include:
Pain if a tumor presses on nerves or muscles
A noticeable lump or swelling
A blockage in the stomach or intestines or gastrointestinal bleeding (if tumor is in abdomen/digestive tract)
