    Cancer can originate almost anywhere in the body.

    - Carcinomas, the most common types of cancer, arise from the cells that cover external and internal body surfaces. and that generally arises from cells originating in the endodermal or ectodermal germ layer during embryogenesis.Lung, breast, and colon are the most frequent cancers of this type in the United States.

    - Sarcomas are cancers arising from cells found in the supporting tissues of the body such as bone, cartilage, fat, connective tissue, and muscle.They can be found in any part of the body. Most of them develop in the arms or legs. They can also be found in the trunk, head and neck area, internal organs, and the area in back of the abdominal cavity (known as the retroperitoneum). Sarcomas are not common tumors, and most cancers are the type of tumors called carcinomas.

    - Lymphomas are cancers that arise in the lymph nodes and tissues of the body's immune system.N.B:Lymph nodes are small collections of lymph tissue that occur throughout the body. The lymphatic system involves lymphatic channels that connect thousands of lymph nodes scattered throughout the body. Lymph flows through the lymph nodes, as well as through other lymphatic tissues including the spleen, the tonsils, the bone marrow, and the thymus gland.

    - Leukemias are cancers of the immature blood cells that grow in the bone marrow and tend to accumulate in large numbers in the bloodstream.
