No, because osteosarcoma usually forms in an immature bone, but in rare cases it can arise in the soft tissue.

Osteosarcoma spreads very quickly and in approximately 1 in 5 cases, it has already spread before it was even diagnosed.

Osteosarcoma starts when the DNA of a healthy bone cell mutates and the cell then tries to make new bone where it’s not needed. This results in a cancerous mass which then turns into osteosarcoma.

Osteosarcoma cancer cells can sometimes spread to other areas of the body and infect them, and the most common area it spreads to is the lungs. This happens because the cancerous cells spread quickly and the first organ they attack is usually the lungs.

As osteosarcoma is a bone cancer, it greatly affects the skeletal system. If someone is suffering from telangiectatic osteosarcoma, it can cause the bones to weaken so much that breaks and fractures can occur even with the smallest injuries. In other cases, people experience redness, swelling and lumps that appear around the infected bone.

When someone gets osteosarcoma, the first thing that happens is a DNA change that develops within a healthy bone cell. This causes the cells to think they need to make another bone when that in fact isn’t the case. This results in poorly formed bone cells that are in fact tumors that can further invade […]

Even though osteosarcoma is the most common type of bone cancer, it’s still considered a rare disease that only accounts for 2.4% of all childhood cancers.

Recurrent osteosarcoma is unfortunately pretty frequent. For patients with an initially localized disease, it’s recurrent in 30-50%, and for those presenting with metastatic disease, it’s as high as 80%.

While osteochondromas can turn into malignant tumors and cause diseases such as osteosarcoma, it’s a very rare occurrence and only happens in approximately 1% of cases.
