Sarcomas are a rare group of cancers that begin in the bones or soft tissues of the body. In other words, sarcoma is a term used to describe bone cancer and cancers that develop in the connective tissues. It accounts for about 1 per cent to 2 per cent of all cancers that affect children, adolescents, and even adults. Although bone cancer can develop anywhere in the body, it mostly develops in the arms and legs.

Since it develops deep in the body and becomes evident after the appearance of a lump, one might not be able to see any significant signs or symptoms. This makes, early diagnosis of sarcoma very crucial.
