cancer. Carcinoma is a
cancer that begins in the skin or
in tissues that line or cover internal organs. Sarcoma is a
cancer that begins in bone,
cartilage, fat, muscle, blood vessels, or other connective
or supportive tissue. Leukemia is a
cancer that begins in blood-forming
tissue, such as the bone marrow, and causes too many
abnormal blood cells to be made. Lymphoma and multiple
myeloma are cancers that begin in the
cells of the immune system. Central nervous system cancers
are cancers that begin in the tissues of
the brain and spinal cord. Also called malignancy.
