What is Bone and Soft Tissue Cancers?
Soft tissue connects, supports and surrounds the organs and structures within the body.
Soft tissue consists of muscles, joints, fat, blood vessels, tendons, synovial tissues (tissues around joints) and nerves. Soft tissue sarcomas form in the soft tissues anywhere in the body but are most commonly found in the legs.
- Symptoms are dependent on the location of the tumour.
- The first symptom that is usually noticed is a painless lump growing in the muscle or under the skin.
- Weight loss
- In most cases, there is no identifiable cause of the soft tissue sarcoma.
- Sarcomas can sometimes occur because of genetic abnormalities in tumour suppressor genes, such as the p-52 (p-glycoprotein) gene or retinoblastoma gene. Tumour suppressor genes keep cells from dividing too quickly. Abnormalities in these genes could cause cells to grow out of control and may lead to cancer.
- Previous chemotherapy can increase a patient's risk of developing soft tissue sarcoma.
- Patients who have received past treatment with radiation therapy have a higher risk of developing sarcoma in that area.
