Osteosarcoma Case Studies
Osteosarcoma
I. General Characteristics
A cancerous (malignant) bone tumor
Usually develops in teenagers (occurs when a teen is growing rapidly)
Most common bone cancer in children
There are about 800 new cases of osteosarcoma in the US each year
Tends to appear in the upper arm, thigh, and shin though it can appear in any bone Can be fatal
If tumor has not spread to the lungs long-term survival rates are better
60% to 80% localized 5-year survival rate
At least 23 types of osteosarcoma
II. Cause
Cause unknown
Risk factors include age, height, gender, ethnicity, radiation to bones, and certain bone diseases and syndromes
Higher risk if it runs in the family
III. Signs and Symptoms
Symptoms include bone fracture, pain, limitation of motion, limping (if in leg), pain when lifting (if in arm), tenderness, and swelling starts in the cells that make bone low grade, intermediate grade, and high grade
IV. Diagnosis
No special tests to find osteosarcoma in people …show more content…
However there are factors that may put people at a higher risk. The risk is the highest for those between the ages 10 and 30, but especially during the teenage growth spurt. This shows that there might be a link between rapid bone growth and possible tumor formation. The risk goes down towards the middle of life then rises again in older age. Children with osteosarcoma are usually tall for their age, again suggesting the link between rapid growth and tumor. This cancer is less common in girls than in boys. Females also tend to get it sooner because of earlier growth spurts. Also affecting race, more African Americans are affected than whites. Those who were treated with radiation for another cancer may have a higher risk of developing osteosarcoma in the place that was treated. People with certain non-cancerous bone diseases like paget disease and Multiple hereditary osteochondromas have an increased risk of developing
