The difference between metastatic bone cancer and metastatic bone cancer is that bone marrow cancers begin and metastatic bone cancers occur when the bone attacks another organ, such as breast or lung cancer. ۔
The difference between primary and metastatic bone cancer is important because it affects the way cancer is treated. It is important for doctors to know that, as soon as possible, they are dealing with primary bone cancer or metastatic bone cancer, so that they can provide appropriate treatment.
Primary Bone Cancer: Types
Primary bone cancer is a very rare form of cancer, less than 0.2% of all cancers. Only in the United States. 2,380 people were expected to be diagnosed with bone and joint cancer in 2008, and 1,470 people were expected to die from primary bone cancer during that period.
Specific types of primary bone cancer target certain age groups and include:
Osteosarcoma: The most common type of primary bone cancer, osteosarcoma is often diagnosed in children and adolescents and can develop during development. Sarcomas are cancers that start in the bones, muscles, fibrous tissues and elsewhere. Osteo is Greek for bone.
Chondroscuma: Another common type of bone cancer, chondrosarcoma rarely affects people under the age of 20. Instead, those most affected are people over the age of 40, whose risk increases with age. A chondrosarcoma begins in the soft tissue called cartilage at the end of the bone.
Evening sarcoma: Like osteosarcoma, evening sarcoma is more common in children and adolescents, with boys often suffering more than girls. This type of tumor can start in bone, tissue or an organ. A common site is the pelvis.
Primary bone cancers often affect the bones and legs, the long bones and the legs.
Primary bone cancer: treatment
Bone cancer surgery is the most common treatment for primary bone cancer, doctors have tried to remove the tumor from the bone. Length saving techniques are tried first, but cuts are often made. Chemotherapy is usually given to kill any remaining cancer cells after surgery. Radiation therapy is not commonly used, as bone cancer cells are resistant to this form of treatment.
Metastatic bone cancer
Metastatic bone cancer is more common than primary bone cancer, as it can be caused by any malignant tumor inside the body. More than 1.2 million people are diagnosed with cancer each year, and half of these cancers spread to the bones, or metastasize. An estimated 350,000 of the 565,650 people who died of cancer in the United States in 2008 had metastatic bone cancer.
Cancer can metastasize to any bone, but often spreads to bones near the center of the body. The spinal cord is the most common site for cancer to spread, and the next most common bones affected by metastatic bone cancer are the pelvis, upper leg bones, upper arm bones, ribs, and skull.
Some types of cancer are more likely to spread to the bones than others. These include breast, thyroid, lung, kidney and prostate cancers. When metastatic bone cancer is observed under a microscope, it is found in cells of the original organs. For example, metastatic bone cancer cells caused by a massive breast tumor will look similar to breast cancer cells, even though they were taken from the bone.
Metastatic bone cancer: Treatment The treatment given for metastatic bone cancer is usually the same treatment given for the original type of cancer. Radiation therapy can also be used to reduce the pain caused by bone cancer, which is a major problem for people with cancer.
Primary and metastatic bone cancer: long-term outlook
As with all cancers, the long-term outlook largely depends on the type and diagnosis of the cancer. The long-term outlook for metastatic bone cancer is not good because the cancer has spread from its place. Usually, the earlier bone cancer is diagnosed, the better the outcome.
