Bone Cancer Bone cancer is when there is an abnormal growth in the amount of tissue in a bone. These strange growths can be either benign or malignant‚ but usually malignant. There are two types of bone cancer; primary and secondary. In primary bone cancer‚ the cancer had actually started in the cells of the bone‚ whilst in secondary‚ the cancer has started in a different area and traveled through the body to the bone. The three main types of bone cancer are osteosarcomas‚ Ewing’s sarcomas‚ and

Bone cancer can be primary bone canceror secondary bone cancer. Primary bone cancer started in the bone; the cancer initially formed in the cells of the bone‚ while secondary cancer started elsewhere in the body and spread to the bone. Examples of primary bone cancer include steosarcoma‚ Ewing sarcoma‚ malignant fibrous histiocytoma‚ and chondrosarcoma. According to the National Cancer Institute‚ USA‚ it is estimated that by the end of 2010 there will have been 2‚650 new cases and 1‚450 deaths

Chapter 10 Muscle The muscular system helps in providing the movement for bones and in doing so allows the body to make complex movements. Muscle is one of the four types of primary tissue. The three kind of muscle tissue that make up the human body are: skeletal muscle‚ smooth muscle‚ and cardiac muscle. Skeletal muscle is voluntary and are usually found attached to bones where they help to produce movement of the skeleton. Smooth muscle is involuntary and are usually found in the walls of the

I learned that osteomalacia means soft bones‚ and that is exactly what the disease is. The mineralization in the bones does not happen properly‚ causing bones to be made up of a collagen matrix with no mineralization covering. This causes bones to be soft‚ making it hard to put any pressure on them at all. People experiencing this will have constant‚ or almost constant‚ pain in bones and ligaments. Osteomalacia can also cause partial fractures in the bones due to weakness. In some cases‚ even muscle

most common name for Osteoarthritis is “Arthritis”. Millions of people are diagnosed with it all over the world. It starts when the protective cartilage that is located on the end of the bones starts to wear down and it causes it to rub on the muscle. Even though it can damage any part of the body that is bones or joints it mainly happens on the hands‚ knees ‚ hips and spine. Some background information for Osteoarthritis is “subdivided by the cause into either idiopathic or secondary forms.”
