Sarcomas are the malignant tumors of connective tissues. They can be grouped into two main types, soft tissue sarcomas and bone sarcomas (bone cancer), both of which are further divided into several subtypes based on their possible cell types of origin. More than one third of soft tissue sarcomas occur in the legs. This type of sarcomas can invade tissue around the original site and can metastasize to other organs, while some soft tissue sarcomas are non-cancerous. The second type of sarcoma includes: osteosarcoma, Ewing’s sarcoma and chondrosarcoma, which are usually diagnosed in children. The treatment of sarcomas depends on the size, location, type and grade of the disease. Besides surgery, chemotherapy and radiation therapy as the traditional treatment options, some innovative biological therapies are also used to activate the potential of the immune system, or being carried out in clinical trials for treating soft tissue sarcomas. Research reports indicate people with genetic abnormalities, or have been exposed to high dose of radiation, cancerigenic chemical are always at a more potential risk of developing this disease.

The subtypes of sarcomas are listed here:


Ewing's sarcoma




Fibroblastic sarcomas


Synovial sarcomas

Vascular sarcomas
