It then lodges its cells to other organs where it stimulates uncontrolled growth. This process of leaving of origin and growing in another part is referred to as metastatic spread (Robert, 2007). Facts and figures There more than 200 different types of cancer. According to National Cancer Institute, Most of these cancers can be sub divided into the following categories. Carcinoma is cancer that starts in the tissues which line (skin) and cover other organs. Sarcoma cancer begins in the cartilage, bone, muscle, fat, blood vessels and other tissue that is connected or supported. Leukemia cancer begins in blood producing tissue, for example, bone marrow.

Examples of these cancers are cervix, colon, and rectum, oral and skin cancer. Cancer screening can decrease mortality for cancers such as cervix, breast, colon and rectum. An increased awareness of breast cancer symptoms and changes can lead to early detection of tumors at an early stage. Almost half of all known cancer cases can be prevented by screening.
