Osteosarcoma, Ewing sarcoma, chondrome
Definition
The term bone cancer is used to describe the presence of benign or malignant tissue changes in the bone area. In addition, there are tumors that cannot be assigned to one or the other group. These forms of bone cancer are called semi-malignant (semi-malignant) tumors. However, these tumors have the property to degenerate further and become malignant.
Introduction
In general, such bone tumors (bone cancer) can be divided into two subtypes: Primary and secondary bone cancer. Primary bone cancer develops directly from bone or cartilage tissue. This form of bone cancer usually occurs in the affected patients at quite similar localizations.
Typical localizations (so-called predilection sites) for primary bone tumors are the zones of longitudinal growth (for example the growth plate). Only the so-called “Ewing sarcoma” is an exception as a primary bone cancer. This form of bone tumor is found in the majority of cases directly in the area of the diaphysis.
In addition, primary bone tumors cause a rather unspecific symptomatology for cancer. Secondary bone cancer, on the other hand, are daughter tumors (so-called metastases) that originate from a tumor located in another part of the body. Secondary bone cancer is particularly common in the area of the spine.
Approximately 80 percent of the causative metastases originate from prostate carcinomas (prostate cancer), breast carcinomas (breast cancer), bronchial or renal cell carcinomas. In direct comparison between these two forms of bone cancer, it can be assumed that secondary bone tumors are much more common. Regardless of the respective form and localization of the tumor, most of the affected patients show quite similar symptoms.
Typical signs of bone cancer include pain and swelling of the skin and subcutaneous tissue in the area of the affected bone. In addition, limbs that are affected by bone cancer usually show a significant limitation of the normal range of motion. Other typical signs of cancer include unexplained weight loss, fever and night sweats.
However, such complaints do not necessarily have to be associated with a malignant tumor. Similar symptoms also occur with other, rather harmless diseases. Nevertheless, persons suffering from persistent bone pain should consult a specialist as soon as possible. This doctor can determine the underlying cause and initiate appropriate treatment at an early stage.
