When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Bone Cancer (Osteosarcoma).
The exact cause of osteosarcoma remains unknown, but researchers have identified several factors that contribute to its development.
The exact cause of osteosarcoma remains unknown, but researchers have identified several factors that contribute to its development. The cancer appears to arise from errors in DNA that occur during periods of rapid bone growth, when cells are dividing quickly to build new bone tissue. These genetic mistakes cause normal bone-forming cells called osteoblasts to grow out of control and produce abnormal bone tissue.
Most cases develop spontaneously without any clear trigger, but certain genetic conditions significantly increase risk.
Most cases develop spontaneously without any clear trigger, but certain genetic conditions significantly increase risk. People with hereditary retinoblastoma, a rare eye cancer, face a much higher chance of developing osteosarcoma later in life. Li-Fraumeni syndrome, another rare genetic disorder, also predisposes individuals to multiple types of cancer including osteosarcoma.
Previous exposure to high-dose radiation therapy, particularly during childhood treatment for other cancers, can damage bone cells and lead to osteosarcoma years later.
Previous exposure to high-dose radiation therapy, particularly during childhood treatment for other cancers, can damage bone cells and lead to osteosarcoma years later. Some researchers are investigating whether certain bone diseases like Paget's disease might also contribute to cancer development, though this connection remains less clear.
Risk Factors
- Age between 10-19 years during peak bone growth
- Previous radiation therapy treatment
- Hereditary retinoblastoma genetic condition
- Li-Fraumeni syndrome
- Paget's disease of bone
- Previous chemotherapy with alkylating agents
- Tall stature and rapid bone growth
- Male gender (slightly higher risk)
- History of bone infarcts or bone infections
Diagnosis
How healthcare professionals diagnose Bone Cancer (Osteosarcoma):
- 1
Diagnosing osteosarcoma typically begins when persistent bone pain prompts a visit to the doctor.
Diagnosing osteosarcoma typically begins when persistent bone pain prompts a visit to the doctor. Unlike growing pains that come and go, osteosarcoma pain tends to worsen over time and often disrupts sleep. The doctor will perform a physical examination, checking for swelling, tenderness, and range of motion in the affected area.

Imaging studies provide the first clear picture of the problem.
Imaging studies provide the first clear picture of the problem. X-rays can reveal abnormal bone growth or destruction, while MRI scans show the exact size and location of the tumor plus any spread to nearby tissues. A CT scan of the chest is essential because osteosarcoma frequently spreads to the lungs, even when the primary tumor seems small.

The definitive diagnosis requires a biopsy, where a specialist removes a small piece of the tumor for examination under a microscope.
The definitive diagnosis requires a biopsy, where a specialist removes a small piece of the tumor for examination under a microscope. This procedure must be performed by an experienced orthopedic oncologist who understands how the biopsy site will affect future surgery. Blood tests measuring alkaline phosphatase and lactate dehydrogenase levels help assess the tumor's activity and provide information about prognosis.
Complications
- The most serious complication of osteosarcoma involves metastasis, where cancer cells spread to other parts of the body.
- The lungs represent the most common site of spread, occurring in about 15-20% of patients at diagnosis.
- Pulmonary metastases can cause breathing difficulties and require additional surgery to remove cancerous nodules from the lungs.
- Treatment itself can lead to significant complications that affect quality of life.
- Chemotherapy drugs used for osteosarcoma can damage hearing, kidney function, and heart muscle.
- Some patients develop secondary cancers years later due to the intensive treatments required to cure the original osteosarcoma.
- Surgical complications may include infection, prosthesis failure, or limb length differences that require ongoing orthopedic care and possible revision surgeries.
Prevention
- Unfortunately, most cases of osteosarcoma cannot be prevented because they develop spontaneously during normal bone growth periods.
- The genetic changes that lead to this cancer appear to occur randomly, without any clear environmental triggers that people can avoid.
- For individuals with known genetic risk factors like hereditary retinoblastoma or Li-Fraumeni syndrome, regular monitoring with imaging studies may help detect tumors early when they're most treatable.
- These high-risk patients should work closely with genetic counselors and oncologists to develop appropriate screening strategies.
- The most important preventive measure involves seeking prompt medical attention for persistent bone pain, especially in children and teenagers.
- While most bone pain in young people results from normal growth or minor injuries, pain that worsens over time, disrupts sleep, or doesn't improve with rest deserves immediate evaluation.
- Early detection and treatment provide the best chance for successful outcomes.
Treatment for osteosarcoma requires a coordinated approach involving multiple specialists at a cancer center experienced with bone tumors.
Treatment for osteosarcoma requires a coordinated approach involving multiple specialists at a cancer center experienced with bone tumors. The standard treatment combines intensive chemotherapy with surgical removal of the tumor, a strategy that has dramatically improved survival rates over the past 30 years.
Chemotherapy typically begins first, using powerful drugs like methotrexate, doxorubicin, and cisplatin to shrink the tumor and attack any cancer cells that may have already spread.
Chemotherapy typically begins first, using powerful drugs like methotrexate, doxorubicin, and cisplatin to shrink the tumor and attack any cancer cells that may have already spread. This initial treatment, called neoadjuvant chemotherapy, usually lasts about 10 weeks and helps determine how well the cancer responds to treatment.
Surgery represents the cornerstone of osteosarcoma treatment, with the goal of removing the entire tumor while preserving as much function as possible.
Surgery represents the cornerstone of osteosarcoma treatment, with the goal of removing the entire tumor while preserving as much function as possible. Many patients can undergo limb-salvage surgery, where surgeons remove the cancerous bone and replace it with a metal prosthesis or bone graft. Amputation becomes necessary only when the tumor involves major blood vessels or nerves, or when limb-salvage surgery cannot safely remove all cancer cells.
After surgery, additional chemotherapy continues for several more months to eliminate any remaining cancer cells.
After surgery, additional chemotherapy continues for several more months to eliminate any remaining cancer cells. Newer treatments under investigation include targeted therapies that attack specific features of cancer cells and immunotherapy drugs that help the body's immune system fight the cancer. Clinical trials offer access to these experimental treatments for patients whose cancer doesn't respond to standard therapy.
Living With Bone Cancer (Osteosarcoma)
Living with osteosarcoma requires significant adjustments for patients and families, particularly since most cases occur during the teenage years when peer relationships and independence are developing. The extended treatment period, typically lasting about a year, often disrupts school, sports, and social activities. Many hospitals provide educational support and social workers to help maintain connections with friends and schoolwork.
