D48.1: Neoplasm of uncertain or unknown behaviour: Connective and other soft tissue

When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.

Connective tissue is found all over the body and fulfills various tasks. Connective tissue contains lots of fine fibers. Thus it can protect or stabilize organs. There is connective tissue beneath the skin and around muscles, for example. Tendons, ligaments and cartilage are also made of connective tissue.
