What is the difference between desmoid tumors and soft tissue sarcoma?

Desmoid tumors are related to a type of cancer called soft tissue sarcoma. Soft tissue sarcomas can metastasize (spread to other parts of the body), while desmoid tumors do not spread. However, desmoid tumors can be aggressive, and may grow into neighboring structures. For this reason, cancer doctors usually care for people with desmoid tumors.
