Fibrosarcoma is cancer originating in fibroblasts, which are a type of cell found in your fibrous tissue that produces collagen. Fibrous tissue is composed of collagen fibers and rows of connective tissue cells.
Fibrosarcoma is a rare soft tissue sarcoma that primarily affects the connective fibrous tissue at the end of a leg or arm bone. It can spread to surrounding soft tissue, such as adipose tissue, tendons, nerves, joint tissue and blood vessels.
One risk of fibrous tissue and bone fibrosarcomas is radiation exposure, a side effect concern if you’ve received previous radiation cancer treatment. And you’re also at a higher risk for this sarcoma if you suffer from other bone diseases, such as Paget’s disease, osteomyelitis and fibrous dysplasia.
A few of the main symptoms of fibrosarcoma are:
- bone fracture
- under skin or bone lump
- pain when using extremities
- range of motion impediment
Common treatment is surgical removal of your fibrous tissue tumor. If your fibrosarcoma cannot be removed cleanly, then amputation may be necessary. Prior to surgery, you may be treated with chemotherapy or radiation in an effort to shrink your fibrous tissue sarcoma.
