Cancer (In General): 

Cancer (In General) What’s cancer? Your body is made up of many small structures called cells. There are many different types of cells that grow to form the different parts of your body. During normal growth and development, these cells continuously grow, divide, and make new cells. This process continues throughout life even after you are no longer growing. The cells continue to divide and make new cells to replace old and damaged cells. In a healthy person, the body is able to control the growth and division of cells according to the needs of the body. Cancer is the uncontrolled growth of abnormal cells anywhere in a body. The abnormal cells are termed cancer cells, malignant cells, or tumor cells. Many cancers and the abnormal cells that compose the cancer tissue are further identified by the name of the tissue that the abnormal cells originated from (for example, breast cancer, lung cancer, colon cancer). Cancer is not confined to humans; animals and other living organisms can get cancer. Below is a schematic that shows normal cell division and how when a cell is damaged or altered without repair to its system, the cell usually dies.

Bone Cancer

Bone Cancer: 

Bone Cancer Bone tumors may be classified as "primary tumors", which originate in bone or from bone-derived cells and tissues, and "secondary tumors" which originate in other sites and spread (metastasize to the skeleton).

Primary bone tumors : : 

Primary bone tumors : Primary tumors of bone can be divided into benign tumors and cancers. Common benign bone tumors may be neoplastic, developmental, traumatic, infectious, or inflammatory in etiology. Examples of benign bone tumors include osteoma, osteoid osteoma, osteochondroma, osteoblastoma, enchondroma, giant cell tumor of bone, aneurysmal bone cyst, and fibrous dysplasia of bone.

Primary bone tumors (Cont.) : 

Primary bone tumors (Cont.) Malignant primary bone tumors include osteosarcoma, chondrosarcoma, Ewing's sarcoma, fibrosarcoma, and other types. Germ cell tumors, including teratoma, often present and originate in the midline of the sacrum, coccyx, or both. These sacrococcygeal teratomas are often relatively amenable to treatment.

Secondary bone tumors : 

Secondary bone tumors Since, by definition, benign bone tumors do not metastasize, all secondary bone tumors are metastatic lesions which have spread from other organs, most commonly carcinomas of the breast, lung, and prostate. Reliable and valid statistics on the incidence, prevalence, and mortality of malignant bone tumors are difficult to come by, particularly in the oldest old (those over 75 years of age). Because carcinomas that are widely metastatic to bone are rarely ever curable, biopsies to determine the origin of the tumor in cases like this are rarely done

The Causes of Bone Cancer : 

The Causes of Bone Cancer Bone cancer is caused due to the abnormality of the cells which make .Bone cancer occurs in the bone cells, these cells are the building blocks of bones. Generally bone cells divide and multiply when the body requires them. During this process old cells are replaced by new one and old one gets die, this is the life cycle of the bone cells. If the life cycle of the bone cells goes wrong then there will be unusual growth in the cells and forms mass tissues which are called as tumors.

Risks Factors: 

Risks Factors Bone tumors are most likely to occur in children and adolescents They are less common in older adults

The Effects of Bone Cancer : 

The Effects of Bone Cancer Weak immune system: Previous cancer history: Metastatic characteristics

Symptoms of Bone Cancer : 

Symptoms of Bone Cancer •Pain in the affected region •Weak bones •Fever •Chills •Night sweats •Loss of weight
