Cancer – a substance that causes cancer – a substance that causes cancer –Examples include tobacco smoke, ultraviolet rays, and asbestos Carcinogen

Cancer Terms Tumor - Benign - Malignant -Possesses the ability to invade adjacent tissues and spread. Does not invade surrounding tissues Abnormal growth of tissue

Cancer Terms – Cont. Metastasis -the spread of cancer from its primary site to other places in the body

Cancer Categories 1. Carcinomas - 2. Sarcomas – Cancer of tissues that cover the body surfaces and linings of the body organs. e.g. – skin or lung Cancers that form in the middle or connective tissues e.g. – cartilage, fat, muscle, or bone

Cancer Categories – cont. 3.Lymphomas – 4. Leukemia - Develop and metastasize in the lymph system e.g. – Hodgkin's disease Cancer of the blood and blood-forming part of the body

Treatment for Cancer Surgery Surgery –Remove the cancerous tissue –Greatest chance for cure –Good if not metastasized

Treatment for Cancer Chemotherapy Chemotherapy –Treatment with anticancer drugs –Side effects – hair loss, anemia, and nausea

Treatment for Cancer Radiation Radiation –High energy rays to kill or damage cells –Attacks reproducing cancer cells

Treatment for Cancer Immunotheropy Immunotheropy –Immune system is stimulated to fight cancer cells –Good for small, early stage cancers
