2 Non Communicable Diseases Non Communicable Disease: WHAT IS IT?  A disease that is not transmitted by another person, or a vector, or from the environment.  Certain habits and behaviors can either increase or decrease the risk of these diseases.

3 Non communicable Diseases  Cancer: A group of diseases characterized by an uncontrollable growth and spread of abnormal cells.  Using your text on page 530 define the following terms:  Tumor  Benign  Malignant

4 Vocabulary  Tumor: An abnormal mass of tissue that has no natural role in the body.  Benign – noncancerous; if you’re benign your fine!  Malignant – cancerous

5 Types of Cancer  Lymphomas: cancers of the immune system.  Leukemias: cancers of the blood-forming organs.  Carinomas: cancers of the glands and body linings, including the skin and linings of the digestive tract and lungs.  Sarcomas: Cancers of the connective tissue, including bones, ligaments, and muscles.

6 Risk Factors  There is no known cause of cancer.  Genetics – family history  Environment – food, water, soil, air  Lifestyles choices – sexual activity, drinking, smoking, drugs  What is a Carcinogen???  Carcinogen: A cancer causing substance.  Tobacco use  Alcohol use  Illegal drug use  Sexually transmitted disease  Radiation – ultraviolet rays from the sun  Dietary factors

7 How can you reduce your risk of Cancer??  Practice abstinence  Be physically active  Maintain healthy weight  Eat nutritious foods  Protect your skin from the sun  Avoid tobacco, drugs, and alcohol  Recognize warning signs of cancer  What type of cancer is most common in the US?  SKIN CANCER

8 THREE TYPES OF SKIN CANCER  Basal Cell Carcinoma: Most common Usually appears on face & ears easiest to detect & treat Does not usually spread.  Squamous Cell Carcinoma: Second most common Appears on sun-exposed parts of body Likely to spread to areas beneath skin.  Melanoma: Least common but most lethal UV radiation from sun or tanning beds can increase risk Important to diagnose in early stages Approximately 70% begin near in or near a mole Highest risk fair skin, freckles, light blue/green eyes.

9 Warning Signs of Skin Cancer  Asymmetrical: An imaginary line drawn through the center of the mole that does not produce matching halves.  Border: Noncancerous moles have smooth edges, suspect moles often have irregular edges.  Color: Be cautious of moles that are intensely black.  Diameter: anything over 10 mm should be removed and checked.  Evolving: if a mole is growing or changing in size, shape or elevation.

10 Methods to Prevent Skin Cancer:  Sun block- SPF 30 or greater  Avoid sun from 10 AM until around 4 PM  Wear light clothing  Wear a hat with a wide brim  Wear sunglasses with UV Protection  Do not go indoor tanning- (it’s also bad for night vision)

11 Warning Signs of Cancer:  C hange in bowel and bladder habits  A sore that does not heal  U nusual bleeding or discharge  T hickening or lump  I ndigestion or difficulty swallowing  O bvious change in wart or mole  N agging cough or hoarseness

12 Detecting and Treating Cancer:  Self examination  Biopsy: the removal of a small piece of tissue for examination  Treatment:  Surgery: removes some or all of cancerous tissue mass.  Radiation therapy: aims rays from radioactive substances at cancerous cells. Radiation kills or shrinks the mass.  Chemotherapy: uses chemicals to destroy cancer cells  Immunotherapy: activates a person’s immune system to recognize specific cancers and destroy them.  Hormone therapy: involves using medicines that interfere with the production of hormones. Treatment kills cancer cells or slows the growth.


14 Define the following terms Using your text starting on page 514:  Cardiovascular Disease  Angina Pectoris  Atherosclerosis  Arrhythmias  Heart Attack  Hypertension  Stroke

15 WARNING SIGNS OF A HEART ATTACK & STROKE:  Heart stops because heart is overworked:  Left arm goes numb  Sweating  Skin is pale or clammy  Chest pain  Unconscious  Shortness of breath  Breathing difficulty  Blood supply to the brain is cut off:  Confusion  Headache  Dizziness  Sweating  Pale and/or redness  Balance is thrown off HEART ATTACKSTROKE

16 Vocabulary  Hypertension (high blood pressure) can be lowered with medication, weight management, physical activity, and proper nutrition most common among people over the age of 35 normal range: 120/80 often called the “silent killer”- having no symptoms in early stages

17 Vocabulary  Atherosclerosis  A build up of fatty materials in your arteries narrows the arteries, making the heart work harder  Cholesterol:  HDL: high density lipoprotein (good)  LDL: low density lipoprotein (bad) causes atherosclerosis

18 Vocabulary Cardiovascular Disease:  A disease that affects the heart, blood, or blood vessels.  Angina- chest pains caused by lack of oxygen  Arrhythmias- irregular heartbeat  Heart attack- caused by blockages of arteries, damage to the heart muscle  Stroke- arterial blockage that disrupts the flow of blood in the brain  Congestive Heart Failure- heart no longer pumps efficiently

19 RISK FACTORS FOR CVD’S  Tobacco Use  High Blood Pressure- have it checked periodically  High Cholesterol- eat less high-fat foods  Physical Inactivity  Excess Weight  Stress  Drug and Alcohol Use  Heredity  Gender  Age  The health behaviors that you practice now are affecting your cardiovascular system!
