The 2 types of osteosarcoma are.
Central tumor osteosarcoma which is also called a medullary tumor.
Surface tumor osteosarcoma which is also called a peripheral tumor.
Osteosarcoma is a form of bone cancer which usually develops in the osteoblast cells that form bones.
The bone cancer osteosarcoma occurs mostly in children, adolescents, and young adults.
Around 800 new cases of osteosarcoma are reported each year in the U.S. Of these cases, about 400 are in children and teens.
Osteosarcoma most often occurs in the long bones that make up the arms and legs, though it can occur in any bone.
It tends to occur in children and young adults.
Symptoms of osteosarcoma include localized bone pain and swelling.
Treatment for osteosarcoma typically involves surgery, chemotherapy, and radiation.
The good news is that 3 out of 4 people who have osteosarcoma can be cured if the osteosarcoma cancer hasn't spread to other parts of the body.
Almost everyone who is treated with limb-sparing surgery also ends up with that arm or leg working well.
Many people who have osteosarcoma will also need physical therapy for several months after surgery.
Osteosarcoma is the most common childhood cancer starting in bones, but is still fairly rare.
Each year, doctors diagnose just 1,000 cases in the U.S.
It's found most often in children and teens between the ages of 10 and 19. When it does occur in adults, people are usually in their 60s, 70s, or 80s.
Once tumor cells such as sarcoma, breast, prostate, thyroid, lung, and renal cancers begin to grow in the bone, a cycle of tumor growth, bone destruction, and formation of woven bone begins, which can result in considerable pain, skeletal fractures, and hypercalcemia.
Osteosarcoma is unfortunately a fast-spreading tumor.
By the time the tumor is found in the limb, it is considered to have already spread.
Osteosarcoma spreads to the lung in a malignant process called metastasis.
Osteosarcoma, the most common primary malignant bone tumor, is composed of spindle cells that produce osteoid.
It is a highly aggressive disease in which dramatic progress has been made in treatment and outcome over the past several decades.
