A sarcoma is a rare kind of cancer. Sarcomas are different from the much more common carcinomas because they happen in a different kind of tissue. Sarcomas grow in connective tissue -- cells that connect or support other kinds of tissue in your body. These tumors are most common in the bones, muscles, tendons, cartilage, nerves, fat, and blood vessels of your arms and legs, but they can happen anywhere. Although there are more than 50 types of sarcoma, they can be grouped into two main kinds: soft tissue sarcoma and bone sarcoma, or osteosarcoma.
Bones and blood are both considered to be connective tissues. Muscle tissue is significant because of its ability to contract and relax in order to exert force on the outside world. There are several different types of tissue that fall into the category of muscle tissue. Smooth muscle tissue, for example, lines the insides of some organs and skeletal muscular tissue is used for movement and for purposeful force. The heart is composed of a specific kind of muscle tissue known as cardiac muscle.
