Cancer Cancer is a group of diseases caused by abnormal cell growth and reproduction. Different kinds of cancer kind affect specific organs ALL forms of cancer involve uncontrolled cell Growth

Cancer (Continued) Healthy organisms grow as a result of cell division in a controlled process. Cancer causes a large amount of uncontrolled cell division or abnormal cells Sometimes cells join together to form a large mass known as a Tumor

Causes of Cancer There are many causes to cancer. But most are caused by exposure to certain chemicals Ex- Tobacco use causes Lung Cancer A chemical that causes cancer is called a carcinogen

Asbestos A carcinogen that was once common in building construction Mineral broke down into particles easily inhaled. Cause lung cancer Mesothelioma

Radon Radon is a radioactive gas present in some rocks The gas seeps from the layers of the rock and soil into homes Gas gets in water causes stomach cancer L-Term exposure = Lung cancer

Birth Defects

Birth Defects A woman who smokes during pregnancy has a greater chance of giving birth to premature baby Stillborn Cleft palate & lip Heart defects Women who drink alcohol during pregnancy: FAS- brain damage and physical abnormalities Visual and hearing problems

Heart Disease Heart disease is the leading cause of death in the United states Heart disease occurs when the arteries that supply the blood are blocked Coronary artery is major vessel supplies blood to heart Chemicals Nicotine narrow arteries Cholesterol from food causes deposits to block arteries Deposits slow or stop blood flow

Kidney Disease and Infections Too many chemicals or wastes in the body such as: uric acid, calcium, ammonia can lead to formations of stone-like masses block flow of urine from Ureter (tube from kidney to bladder) Had a Kidney infection cancelled Tour

Asthma Persons with Asthma have difficulty breathing Bronchi = Air passages swell Cleaning products aerosol deodorants pesticides can cause asthma
