Metastases of bone tumors are called osteoclastic. They can develop as a result of malignant neoplasms of various organs and tissues: the digestive system, the genitourinary system, the mammary glands, the ovaries, the prostate gland, and the brain.
**Metastasis of a bone tumor** Metastasis of bone tissue is the spread of malignant cells throughout the body. The main symptoms in this case are skeletal deformation, pain and cramps, signs of cancer in other organs. Diagnosis of metastatic bone lesions is usually difficult, since patients with a primary tumor rarely turn to an oncologist. Doctors listen to people's complaints about frequent fatigue, weakness and rapid weight loss. Symptoms of bone tissue affected by metastases:
* bone pain during movement and at rest; * local and distant pain syndromes; * sharp weight loss; * unmotivated body temperature up to 39 degrees; * chronic anemia. **Causes of tumor metastases** There are several reasons for the development of a secondary disease. The main reason for tumor metastasis is active cell division. In addition, metastases affect tissues only when secondary foci of neoplasms appear, affecting neighboring systems and organs.
