Q: what is the difference between osteosarcoma and ewing's sarcoma?

Sub types: Both are sarcomas occurring mostly in young adults and children mainly. Osteosarcomas always start in the bone and are more common; ewings type sarcomas occur in the bone and other soft tissue sites also. Ewings often spread to other areas unlike osteosarcoma.

Q: what is the difference between chondroblastic osteosarcoma and chondrosarcoma?

The first is a type: Of bone cancer with predominantly cartilage producing cells; while the other is a cancer of the cartilage tissue itself. For specific concerns ask your oncologist. Good luck.

Q: what is the difference between a fibroma and osteochondroma?location is below the knee and looks a lump inside the leg and is painless.what can it be?

Bone vs. soft tissue: Lesion if palpable most likely soft tissue in origin and can be defined on MRI. Osteochondroma is an osseous lesion where fibroma usually soft tissue and can arise from any fibrous tissue site in lower leg such as tendon or fibrous tissue between muscle planes. Bx makes the required dx for treatment

Q: can other disorders develop from osteosarcoma?

Yes, from treatment: Osteosarcoma is an aggressive bone tumor treated with chemotherapy, radiation, and surgery. The intense treatment can cause later problems, including bone fractures and osteoporosis, neuropathy, loss of fertility, chronic pain, neuropathy, and changes in cognitive abilities. Secondary cancers can develop in the areas where radiation was received.

Q: how can you prevent osteosarcoma?

You usually can't: Osteosarcoma is a very rare cancer. Of 300 million people in the us, there are about 800 cases a year. Usually it occurs randomly, but rare cases are due to genetic disorders, preexisting benign conditions (paget's etc.) or radiation. Other than avoiding radiation, there is not much you can do. That being said, the chances of getting osteosarcoma in the first place are very low.

Q: can you have osteochondroma on your l5?

Yes: Osteochondromas usually occur around the knee. They are rare, but do occur in the spine. When they do , they usually occur in the neck. So an osteochondroma arising from L5 is quite rare, but a described entity.

Question 1

what is the difference between osteosarcoma and osteochondroma?

Accepted Answer

Cancer: Osteosarcoma is a malignant (cancerous) tumor of bone. Osteochondroma is a type of benign tumor, usually occurring in bones near joints. Though benign, osteochondromas can lead to disfigurement and pain and may require surgical removal.

Question 2

what is the difference between osteochondroma and osteosarcoma tumors?

Accepted Answer

Benign vs cancer: Osteochondromas are the most common form of non-cancerous bone tumors, usually look like they are growing on the bone surface, and do not spread beyond the affected bone. Osteogenic sarcomas are aggressive cancerous bone tumors that typically cause destruction of the involved bone as well as producing new bone in a haphazard fashion.

Question 3

do osteosarcoma and osteochondroma look the same on xray?

Accepted Answer

No: They have very different imaging characteristics.

Question 4

how do you know if somebody has osteochondroma or osteosarcoma? do you have to wait for biopsy results?

Accepted Answer

Almost never: Osteochondroma and osteosarcoma look very different on x-ray, ct and mri. Osteochondroma can be confidently diagnosed with imaging alone. There is <1% chance of an osteochondroma turning into a chondrosarcoma. In that rare event, it's usually a low grade one that almost never spreads. For osteosarcoma, there is usually strong suspicion based on imaging, but a biopsy is needed to confirm.
