Can osteosarcoma be detected in a blood test?
Blood tests. Blood tests are not needed to diagnose osteosarcoma, but they may be helpful once a diagnosis is made. For example, high levels of chemicals in the blood such as alkaline phosphatase and lactate dehydrogenase (LDH) can suggest that the osteosarcoma may be more advanced.
How is osteosarcoma cancer diagnosed?
A bone scan is a way to find out whether or not osteosarcoma may have spread to other bones beyond the place it started. Biopsy. A biopsy is the removal of a small amount of tissue for examination under a microscope. Other tests can suggest that a tumor is present, but only a biopsy can make a definitive diagnosis.
When is osteosarcoma diagnosed?
It is the most common type of cancer that arises in bones, and it is usually found at the end of long bones, often around the knee. Most people diagnosed with osteosarcoma are under the age of 25, and it is thought to occur more often in males than females.
How is canine osteosarcoma diagnosed?
Diagnosis of Canine Osteosarcoma Imaging includes survey radiographs, and may be supplemented by magnetic resonance imaging (MRI) and/or computed tomography (CT) and nuclear scintigraphy. Imaging studies should include the primary tumor site and common sites of metastasis.
Can you feel osteosarcoma?
Most people who have osteosarcoma don’t feel or look sick. An osteosarcoma tumor may cause a dull aching pain in the bone or joint around the tumor. Often, there is a firm swelling or lump in the area of the pain.
How often are children diagnosed with osteosarcoma?
Each year in the United States, about 400 children and teens younger than age 20 are diagnosed. Osteosarcoma is the third most common cancer in teens, after lymphomas and brain tumors. It is extremely rare in children before age 5. Osteosarcoma has been found in long-term survivors of other cancers who were treated with radiation therapy.
Is there a way to detect osteosarcoma early?
Find out how osteosarcoma is tested for, diagnosed, and staged. Catching cancer early often allows for more treatment options. Some cancers may cause signs and symptoms early in the course of the disease, but that’s not always the case. Can Osteosarcoma Be Found Early?
Do you need a biopsy if you have osteosarcoma?
But other imaging tests might be needed as well. Even if results of an x-ray strongly suggest a person has osteosarcoma, a biopsy (described below) will still be needed to confirm that it is cancer rather than some other problem, such as an infection.
Who is at higher risk of developing osteosarcoma?
African-American children have a higher risk of developing osteosarcoma than Caucasians. Each year in the United States, about 400 children and teens younger than age 20 are diagnosed.

How does a doctor test for osteosarcoma cancer?
Often, the doctor can aim the needle by feeling the suspicious area if it’s near the surface of the body. If the tumor can’t be felt because it’s too deep, the doctor can guide the needle into the tumor using an imaging test such as a CT scan.
What are the chances of survival for osteosarcoma?
People being diagnosed with osteosarcoma now may have a better outlook than these numbers show. Treatments improve over time, and these numbers are based on people who were diagnosed and treated at least 5 years earlier. Factors other than the stage of the cancer can also affect survival rates.
Can a PET scan show the spread of osteosarcoma?
PET scans can help show the spread of osteosarcomas to the lungs, other bones, or other parts of the body. They can also be used to see how well the cancer is responding to treatment. Many machines can do a PET and CT scan at the same time (PET/CT scan).
