Definition of Disease
Osteosarcoma is a malignant neoplasm of bone composed of a malignant connective tissue stroma with evidence of malignant osteoid, bone, or cartilage formation.
Epidemiology of Disease
Osteosarcoma is an early cancerous growth that usually occurs to adolescences even though it may appear on the elderly in some cases. Basic bone malignancy seems to be the most common form of cancer that strikes the long bones. However, this may differ with the difference in age (Savage, & Mirabello, 2011). It is not easy to detect osteosarcoma until puberty, even though it may appear at childhood. The osteosarcoma risk is high at the youth period and declines ...view middle of the document...

Osteosarcoma is cancerous, and it is a bone marrow disease which attack obsolescence and teenager to adult. The tumors also weaken the bones slow down normal movement and causing fractures. Osteosarcoma is a common kind of bone cancer. These are the signs and symptoms listed below according to Caring four Cancer.
* Fractures - Osteosarcoma can weaken the bone where it starts and this sometimes, though not often makes the bone break. About one-third of telangiectatic osteosarcomas, which are rare, cause a fracture at the tumor site.
* Lump - Depending on where the tumor is, you might be able to feel a lump.
* Pain - The most common symptom of osteosarcoma is pain in the bone where the cancer has started. At first, the pain is not constant, and it might be worse at night.

There are several tests that will perform to diagnose this patient such as a biopsy, blood tests, bone scan, CT scan, MRI scan, bone x-ray, and PET scan.
* Open biopsy – The surgeon finds the tumor and cut a piece of tissue.
* Blood test – A technician will take blood from the patient and send it to the lab for testing. The blood test can be helpful to determine how serious and advanced the osteosarcoma is. There are different levels of the following chemicals in the blood mean that the cancer will be more difficult.
