Pelvis and hips metastases

Bone metastases or osseous metastatic disease are cancerous lesions that result from spread of another primary cancer (a cancer somewhere else in the body). They are more common than primary bone cancer. Some of the most common cancers to spread to bones are: breast, prostate, lung, kidney and thyroid.Metastatic disease affects the regular process of decay and growth of bone. As a result the structure of the bone changes. There are two type of bone metastases, osteoblastic metastases and osteolytic metastases. Osteoblastic (sclerotic) metastases occur when cancer cells invade and cause too many bone cells to form. The bone then becomes very dense. Osteolytic metastases occur when the cancer breaks down too much bone resulting in it being destroyed and weakened. The former is the more common type.
