Soft tissue sarcoma is a type of cancer that begins in the soft tissues of your body.

Soft tissues connect, support and surround other body structures. The soft tissues include muscle, fat, blood vessels, nerves, tendons and the lining of your joints.

Many types of soft tissue sarcoma exist. Some types are more likely to affect children, while others affect mostly adults.

Soft tissue sarcoma can occur anywhere in your body, but the most common types occur in the abdomen and in the arms and legs.
