Osteosarcoma and Bone Fibrous Histiocytoma Treatment

Stages of Osteosarcoma and Malignant Fibrous Histiocytoma of Bone

After osteosarcoma or malignant fibrous histiocytoma (MFH) has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body.

The process used to find out if cancer has spread to other parts of the body is called staging. For osteosarcoma and malignant fibrous histiocytoma (MFH), most patients are grouped according to whether cancer is found in only one part of the body or has spread. The following tests and procedures may be used:

There are three ways that cancer spreads in the body.

The three ways that cancer spreads in the body are:

When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if bone cancer spreads to the lung, the cancer cells in the lung are actually bone cancer cells. The disease is metastatic bone cancer, not lung cancer.

Osteosarcoma and MFH are described as either localized or metastatic.
