DefinitionSoft tissue sarcoma is a disease in which cancer cells are found in soft tissue in the body. Soft tissue includes muscles, tendons, connective tissue, fat, blood vessels, nerves, and joint tissue. There are many types of soft tissue sarcoma.
CausesCancer occurs when cells in the body divide without control or order. Eventually these uncontrolled cells form a growth or tumor. The term cancer refers to malignant growths. These growths can invade nearby tissues including the lymph nodes. Cancer that has invaded the lymph nodes can then spread to other parts of the body.It is not clear exactly what causes these problems in the cells, but is probably a combination of genetics and environment.
