  2. Asthma • Affects 10% of Canadian population • Characteristics: • Chronic inflammation of bronchi and bronchioles • Overproduction of mucus • Muscular contraction of airways • Symptoms: • Coughing, wheezing, tightening of chest • Extreme situations: blue lips and fingernails • Cause: • Partially genetic but aggravated by environmental factors

  3. Cystic Fibrosis • 4% of Canadians carry defective allele, 1/3600 with disorder • Characteristics: • Unusually thick, sticky mucus produced by all organs • Symptoms: • Rattling cough, which expels mucus • More prone to lung infections • Difficulty digesting food, due to excess mucus production in pancreas • Cause: • Recessive genetic disorder; defective gene for mucus production

  4. Respiratory Infections • Tuberculosis • Bacterial infection caused by Mycobacterium tuberculosis which invade and destroy lung tissue • Coughing up blood, chest pain • Pneumonia • Infection of lungs caused by virus, bacteria, or fungi • Causes inflammation of lining of bronchi, bronchioles, and alveoli • Pus and mucus accumulate in alveoli

  5. Lung Cancer • Characteristics: • Abnormal cell growth in lungs that interferes with normal lung function and block airways, can metastasize to other organs • Symptoms: • Chronic cough, coughing blood or phlegm, chest pain • Cause: • 85% of cases caused by cigarette smoke • Also air pollution and work-related chemicals

Canadian Cancer Stats 2012 • Cancer is the leading cause of death in Canada (30%) and heart disease is 2nd (20%) • About 2 in 5 Canadians will develop cancer in their lifetimes and 1 in 4 will die of the disease. • 5 year survival rate for lung cancer is 16% Cancer statistics for men and women in Ontariofor 2012 • 4,400 men diagnosed with lung cancer and 3,600 will die • 4,100 women diagnosed with lung cancer and 3,200 will die For men and women in Ontario, lung cancer is the leading cause of cancer death in 2012
