Bone Cancer : A Rare Form Of Cancer

Osteosarcoma is also called osteogenic sarcoma in medical term (“Osteosarcoma”, n.d.). This cancer usually develops in growing bones. Although it can occur at any age, it‘s most commonly found in teenagers and young adults and is slightly more common in males than females. Any bone in the body can be affected, but the most common sites are the arms or legs, particularly around the knee joint(“Osteosarcoma: An Introduction.”, 2012). This cancer is caused by benign tumors and other bone diseases, radiation exposure, genetic factors, children, adolescents, males more than females.(“Osteosarcoma: An Introduction.”, 2012)

The bone is made up of combined bones, bone marrow. Bone marrow is found in the middle of the main bone and it has blood vessles.There is two types of bone marrow are the red and the yellow. This type of cancer my effect the red blood cells, white blood cells, and

Ewing’s Sarcoma comes in several different forms: Ewing sarcoma of bone, Extraosseous Ewing sarcoma, Peripheral Primitive Neuroectodermal tumor (pPNET), and Askin tumor. [3]The most prominent type is Ewing’s sarcoma is of the bone, having a high percentage of approximation 87

Osteosarcoma is an ancient disease that still has some mystery behind it. Osteosarcoma is a type of cancer that starts in the bones. It is also the most common type of bone cancer, and makes up 65% of all bone cancer. However, it is a very rare cancer and has fewer than 20,000 cases per year in The USA. The cells that form an osteosarcoma make bone matrix, similar to osteoblasts. However, the bone matrix of an osteosarcoma is not as strong as a bone matrix from an osteoblast, and therefore is not as strong as normal bones. The most common age group affected by osteosarcoma is children and young adults. However, osteosarcoma can occur at any age. Osteosarcoma is most commonly found in areas of the bone that grow quickly, which is why children are more likely to get this type of cancer. The most common place to find osteosarcoma is the end of long bones, especially in the knee, distal femur, and proximal tibia. The proximal humerus is typically the most common site. The treatments of

Osteosarcoma(OS) is a primary malignant tumor of bone which is characterized by the formation of osteoid tissue. Although it is the most common malignancy of long bones after multiple myeloma [2], it is a relatively rarer entity in the craniofacial region. About 6% of Oss arise in the jaws .The estimated incidence of the new cases of Jaw OS (JOS) per year is 0 .07 in 100,000. (1) The etiology of OS is unknown, but some risk factors such as a previous history of ionizing radiation, alkylating agent, retinoblastoma and benign bone lesions such as paget disease and fibro osseous dysplasia have been associated with the development of head and neck OS.(2-4) JOS occur with a peak in the third through fifth decades of life. The mean age is

My peers may not know a lot about osteosarcoma so I’m going to cover a few things about this bone cancer. My secondary audience could also be any person interested in learning more about this type of cancer. Purpose

during adolescent growth, which could be why 80% of all osteosarcoma childhood cases occur in the lower long bones and at the time of puberty (Mirabello & Savage 5). The chances of a cell dividing uncontrollably are increased at a time of rapid cell growth when there is many more cells dividing that could go suddenly go uncontrolled, and therefore the answer of how osteosarcoma is ignited could lie in puberty. On the contrary, the answer may be found in a small gene that prevents osteosarcoma patients from responding well to the chemotherapy treatment.

Ewing Sarcoma is a type of tumor that forms in bone and soft tissue. It may occur in any bone, but it is most often found in hip bone, ribs, or in the long bones such as femur. Ewing Sarcoma typically occurs more in children and young adults, between the ages of 10- 20. Males are affected more than females.

Multiple myeloma damages the bones and causes other health problems because of the effect on blood cells. The disease progresses and reduces

It can occur at any age, but is most common in teens. It is usually found in the long bones of the legs and arms. Sometimes, the situation requires amputation. Cancer forms when cells start to grow too quickly and overproduce. The cancerous cells usually form a tumor.

There are 206 bones in the adult human skeleton; these bones relate to movement, posture, and protect internal organs (American society of Clinical Oncology, 2012).Bones connect to bones with ligaments and are covered and protected by cartilage (American Society of Clinical Oncology, 2012).Cancer of the bone is rare but is caused by normal bone marrow and tissues inside the bone that change and form tumors(American Society of Clinical Oncology, 2012). The tumor happens in the bone and is benign it does not spread (American Society of Clinical Oncology, 2012). The benign tumor can press against surrounding tissues and weaken the bone it it grows big enough (American Society of Clinical Oncology, 2012). Malignant bone tumors break the surrounding tissue and cortex, hard covering of the bone (American Society of Clinical Oncology, 2012). The tumor can then get into the bloodstream and spread all over the body (American Society of Clinical Oncology, 2012). Osteosarcoma and ewing sarcoma are the two most common type of bone cancer (American Society of Clinical Oncology, 2012). Chondrosarcoma is more common in adults and is cancer of the cartilage (American Society of Clinical Oncology, 2012). The last type of bone cancer is chordoma which usually starts in the lower spinal cord (American Society of Clinical Oncology, 2012). Ewing sarcoma is a type of bone cancer that affects the hip, rib, and middle of bone most often (National Cancer Institution, 2015). Ewing

Bone cancer is considered as a rare disease in which cancer cells grow in the bone tissue. It requires to be treated immediately because when bone tumor grows, it presses on healthy bone tissue and can destroy it, which causes pain and swelling where the tumor is located. People has bone cancer will experience burning pain at the early stage and as the tumor develops, the pain become more persistent. Beside that, the bone can easily break due to the cancerous cells can weaken the bone. In some cases, if the tumor grows near a joint, it may make normal movements

To illustrate the danger of canine osteosarcoma, imagine a ten-year-old Saint Bernard that has symptoms of bone cancer. The dog has extreme bone pain and loss of appetite. The dog’s owner and veterinarian decide to give the Saint Bernard pain medication. A few months later, the dog cannot walk and dies. Unfortunately, osteosarcoma is the most common type of bone cancer in larger dogs and there is no cure. The most effective way to treat canine osteosarcoma is with amputation and chemotherapy because it manages bone pain, improves the survival time, and increases the survival rate.

For this unit I chose Ewing's sarcoma, a malignant bone tumor, and a primary bone cancer that originates in bone cells. According to Derrer, David a medical reviewer for WebMD, Ewing's sarcoma is a family of tumors that is located in the long bones of the legs and arms, or bones in the chest, pelvis, back, or head (2014). It also develops in the skull or flat bones of the trunks. The most common symptoms of Ewing's sarcoma is pain, however symptoms might vary, depending on the size and location of the cancer. Other symptoms may also include swelling, tenderness, or stiffness in the affected area, fracture, fatigue, fever, weight loss, and anemia. The exact cause of Ewing sarcoma is not fully understood. There seems to be no known risk factors

“These tumors can cause pain, limit joint movement, and exert pressure on nerves, blood vessels, and surround tissues” (2). Multiple tumors can also “disrupt bone growth and can cause disturbances of the arms, hands, and legs, leading to
