However, just because breast cancer has spread to the spine doesn't mean that it will spread to other areas. Doctors can treat the new tumors with radiation and new medications called bisphosphonates can block the progression of tumor cells in the bone and prevent the cancer from spreading to other organs.
The process of spreading is called metastasizing. If a tumor spreads to the bone, it is called bone metastasis. Cancer cells that have metastasized to the bone can damage the bone and cause symptoms. Various treatments are available to control the symptoms and the spread of bone metastases.ancer cells that spread to bone are harmful in two ways: The tumor may eat away areas of bone, creating holes called osteolytic lesions. This process can make bones fragile and weak, so that they break or fracture easily. These areas may be painful.
