fulguration destruction of tissue by electric spark
retinoblastoma an example of a known type of inherited cancer
modality method of treatment
radioresistant tumor tumor requires large doses of radiation to produce death of cells
notation T1N2MO means tumor is present with palpable regional lymph nodes and no metastasis
electrocauterization treating tissue with electrically generated heat

chemical carcinogen an agent (hydrocarbon, insecticide, hormone) that causes cancer
mitosis replication of cells; two identical cells are produced from a parent cell
oncogene region of genetic material that causes cancer; found in tumor cells or viruses
RNA cellular substance (ribonucleic acid) that is important in protein synthesis
virus infectious agent that reproduces by entering a host cell and using the host's genetic material to make copies of itself
DNA genetic material within the nucleus that controls replication and protein synthesis
mutation change in the genetic material of a cell

inflammatory characterized by redness, swelling, and heat
medullary tumors are large, soft, fleshy
necrotic containing dead tissue
fungating mushrooming pattern of growth
ulcerating characterized by large, open, exposed surfaces
