A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
The outer shell of the long bone is made of cortical bone also known as compact bone. [1] This is covered by a membrane of connective tissue called the periosteum.Beneath the cortical bone layer is a layer of spongy cancellous bone.
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1] Bone metastases can be classified as osteolytic, osteoblastic ...
Around 550 cases of primary bone cancer – a cancer that begins in the bones – are diagnosed in the UK each year
Deaths due to malignant neoplasms of the bones and joints account for an unknown number of childhood cancer deaths. Mortality rates due to osteosarcoma have been declining at about 1.3% per year. Long-term survival probabilities for osteosarcoma have improved dramatically during the late 20th century and approximated 68% in 2009. [2]
Osteochondroma is the most common benign tumor of bone. [1] [2] The tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones ().[3] [4] It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone.
Pain caused by cancer within bones is one of the most severe forms of pain. Because of its severity and uniqueness with respect to other forms of pain, it is extensively researched. According to studies of bone cancer in mouse femur models, it has been determined that bone pain related to cancer occurs as a result of destruction of bone tissue ...
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
