What is the pathophysiology of osteosarcoma?
Osteosarcoma is a type of bone cancer that arises from abnormal growth of osteoblasts, which are the cells that form new bone tissue. This leads to the formation of immature bone tissue (osteoid) within the tumor. Osteosarcoma commonly occurs in the long bones of the body, such as the arms and legs, and can metastasize to other organs, particularly the lungs.
What are the cells of bone tissue called?
Osteocytes
What are the cells of the bone?
They're called OSTEOCYTES calcifying together in a matrix tissue of bone matter.
What causes an osseous neoplasm?
An osseous neoplasm, or bone tumor, can be caused by genetic mutations, previous radiation exposure, or Paget's disease. Some tumors may also develop without a known cause. These neoplasms can be benign or malignant.
What is a piece of necrotic bone tissue called?
A piece of necrotic bone tissue is called sequestrum. It refers to a segment of dead bone separated from healthy bone as a result of avascular necrosis or other conditions affecting blood supply to the bone.
What is the medical term meaning Malignant tumor of connective or supportive tissue?
Sarcoma (for examp. Langerhern Cell Sarcoma, Sarcoma of Ewing). addition! Reticulosarcoma (means sarcoma of the reticulocyte cells) A malignant tumor of connective tissue is called Sarcoma.

What is the medical term meaning malignant tumor that arises from connective tissues including hard tissues soft tissues and liquid tissues?
The perioisteum is the connective tissue covering the bone.
What is the medical term meaning malignant bone tumor in which osteoblasts multiply uncontrollably?

What is bone cancer and what are the physical effects on the bone?
Chondrosarcoma most commonly affects the bones of the pelvis and hips.Bone cancer is a malignant (cancerous) tumor of the bone that destroys normal bone tissue. Not all bone tumors are malignant. In fact, benign (noncancerous) bone tumors are more common than malignant ones. Both malignant and benign bone tumors may grow and compress healthy bone tissue, but benign tumors do not spread, do not destroy bone tissue, and are rarely a threat to life.Malignant tumors that begin in bone tissue are called primary bone cancer. Cancer that metastasizes (spreads) to the bones from other parts of the body, such as the breast, lung, or prostate, is called metastatic cancer, and is named for the organ or tissue in which it began. Primary bone cancer is far less common than cancer that spreads to the bones.
