Are there different types of cancer?
Carcinomas are cancers that start on the surface or lining of a body organ. The surface or lining may be on the inside of the body (for example, the lungs, bowel, bladder, stomach, or uterus) or on the outside (for example, the skin). Around nine out of 10 cancers are carcinomas.
Cancers that start in the body’s bones, fat, muscles, tendons, cartilage or some other tissues are called sarcomas.
Melanomas are cancers that start in the cells that make our skin colour.
Lymphomas are cancers that start in cells called lymphocytes. These cells are in the bone marrow and lymph nodes, and they help us to fight infection.
Cancers of the white blood cells are called leukaemias. We need white cells to fight infection.
Myelomas are cancers of the plasma cells in bone marrow. These cells make antibodies that help us to fight infection.
Nerve cell tumours
Cancers that start in the cells of the brain or the spinal cord are called nerve cell tumours.
Germ cell tumours
Cancers that start in the cells that make sperm (in men) and eggs (in women) are called germ cell tumours.
