Sarcomas are rare tumors and comprise about 1% of adult cancers and about 15% of childhood cancers. They are classified into two groups based upon where the tumor started:

  • Bone
  • Soft tissue (this includes muscle, fat, nerve, cartilage and blood vessels)

Most sarcomas do not have any symptoms, but can be discovered as a lump or swelling that does not go away, which may or may not be painful.

Risk factors include genetic conditions such as:

Other risk factors include chromosomal alterations and, rarely, radiation exposure especially in childhood. According to the American Cancer Society, radiation exposure accounts for less than 5% of sarcomas. Exposure to vinyl chloride and arsenic are linked to development of liver sarcoma.

There are currently no screening tests for sarcoma, so it is important to know if you have a family history of sarcoma or any of the genetic conditions listed above.  If so, you may want to ask your healthcare provider about genetic testing.

Most sarcomas are treated with a combination of surgery and radiation. The radiation is used to kill any areas of cancer that were not seen and removed during surgery. Since sarcoma is a rare cancer, it is best to seek treatment and care at a facility that has a dedicated sarcoma clinic. The University of Michigan sees around 250 new sarcoma cases per year, and has the only Multidisciplinary Sarcoma Clinic in the state.
