The tumor may be localized at the end of the long bone (commonly in the metaphysis). Most often it affects the proximal end of tibia or humerus, or distal end of femur. Osteosarcoma tends to affect regions around the knee in 60% of cases, 15% around the hip, 10% at the shoulder, and 8% in the jaw.
Bone tumor. 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 ...
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [2] Usually the person cannot walk. [3] A hip fracture is usually a femoral neck fracture.
Ewing sarcoma is a type of pediatric cancer [5] that forms in bone or soft tissue. [1] Symptoms may include swelling and pain at the site of the tumor, fever, and a bone fracture. [2] The most common areas where it begins are the legs, pelvis, and chest wall. [4] In about 25% of cases, the cancer has already spread to other parts of the body at ...
A latent cyst is located away from the epiphyseal plate and is more likely to heal with treatment. [4] It is typically diagnosed in under 20 year olds. [1] Although unicameral bone cysts can form in any bone structure, it is predominantly found in the proximal humerus and proximal femur; additionally, it affects males twice as often as females ...
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips (oral cancer), voice box (laryngeal), throat (nasopharyngeal, oropharyngeal, [ 1 ] hypopharyngeal), salivary glands, nose and sinuses. [ 5 ]
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 ...
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [ 1 ] This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst.
