Bone is a strong and tough connective tissue with major functions of protecting our internal organs, muscles, and providing locomotion. Bone tumors are classified into two categories: Primary Tumors and Secondary Tumors. Primary tumors are bone cancers that originate from the bone itself and are very rare. Secondary tumors are metastatic bone cancers that originate or spread from other sites, such as prostate cancer, kidney cancer, breast cancer, etc. Secondary bone tumors are 50 to 100 times more common compared to primary tumors. In most cases, bone cancers cause severe pain and require many therapeutic strategies. Primary bone tumors can be classified as bone cancer or benign tumors.
Malignant bone tumors are rare when compared to benign tumors. Malignant bone tumors are cancerous and are able to metastasize or spread. There are 3 classes of malignant bone tumors:
Benign tumors are localized. They are not cancerous and are not able to spread. The following are the different types of benign bone tumors:
Secondary bone tumors are metastasized, in other words they originated from other organs, such as prostate, kidney, and breast cancer, etc.
The most common symptom of bone cancer is pain. Pain usually stays for weeks or months before the patient seeks help. Pain may gradually increase as the size of the tumor increases. Other associated symptoms can be fatigue, anemia, fever, and weight loss.
Ewing's sarcoma is treated by chemotherapy and radiotherapy. There are number of chemotherapy treatment options for bone tumors. If the response due to chemotherapy is greater than 90% necrosis, then a better prognosis s expected. Medications are prescribed based on bone density and the expected bone loss.
Amputation may be considered if all other measures fail. The amputation can be above or below knee, above or below elbow, or the entire limb. It all depends upon the radiographic results after every treatment attempt.
