1. Carcinogens=cancer causing agents
Cancer=Abnormal, uncontrolled cell growth
Normal body Cell
Cancer Body Cell
Carcinogens=cancer causing agents

2. 2 Types Tumor=Cells reproduce and multiply to a mass of tissues
Noncancerous Tumors=Benign Tumors, do not kill healthy tissue
Cancerous Tumors=Malignant Tumors,
conquer and destroy all tissues
Metastasis=spreading of a malignant tumor throughout the body.

3. Cancer is classified by the type of tissue it develops in
Carcinoma=develops in linings of body organs (lungs, stomach, breast)
Sarcoma=develop in connective and supportive tissues (bones, muscles, tendons)
Lymphoma=develops in lymphatic system (Hodgkin Disease, Leukemia)

4. Diagnosing Cancer Yearly Physical Exams 1. Go to same doctor
2. Keep your records
Self Exams (Skin, Breast, Testicular)
1. Perform once a month EVERY month
Biopsy=removal of a small piece of tissue to be checked for cancer

5. Treatment of Cancer Surgery=Remove tumor or body part
Radiation=used when tumor is in an awkward place on the body
Chemotherapy=Anticancer medications administered seek out abnormal cells
Hormone Therapy=injections used to prevent spread of cancer cells

6. Statistics Melanoma=Most common cancer
Respiratory Cancers=(Lungs & Larynx)
Causes most deaths of all Cancers
Digestive System Cancers=Colon & Rectal cancers are the 2nd most common cancers and are due to diet choices.
Reproductive Cancers=Males-Prostate 50+
Testicular 15-30
Women-Cervix 15-25
Breast 40+

7. Warning Signs Change in Bowel Habits A sore that doesn’t heal
Unusual bleeding or discharge
Thickening or a lump on body
Indigestion or difficulty swallowing
Obvious change in wart or mole
Nagging cough or hoarseness

8. Prevention Know your health history Do self exams once a month
Get yearly check-ups
Choose food high in fiber low in fat
Avoid sunburns & excessive UV rays
Don’t smoke
Exercise regularly

9. Melanoma The most serious type of skin cancer.
When people spend time in the sunlight, the melanocytes make more melanin and cause skin to tan. If skin receives too much UV light melanocytes may begin to grow abnormally and become cancerous.
Each year 50,000 people in the US learn they have melanoma.
Melanoma is one of the most common cancers in young adults.

10. Who gets Melanoma? Blue/green eyes, blonde/red hair, fair skin
History of sunburns or high UV exposure
Prior personal or family history of melanoma

11. Melanoma Exam A=Asymmetry Lesions are typically irregular in shape
B=Border
Lesions often have uneven border
C=Color
Lesions contain many shades of brown/black
D=Diameter
Lesions are often more than 6 millimeters (pencil eraser)
E=Evolving
Lesions often grow in size or height rapidly

15. Each cigarettes contain 43 different chemicals know to cause cancer
Tobacco
What is in a cigarette?
Each cigarettes contain 43 different chemicals know to cause cancer
Cyanide, formaldehyde, arsenic, tar, nicotine, DDT, nitrobenzene, ethanol, toluene, lead
How much does a pack cost?
Is it worth it?

16. Stop Smoking Time Lapse Effect
20 minutes= Blood pressure & Heart rate drop
12 Hours= Carbon monoxide levels drop back to normal
2-3 weeks= Circulation improves and lung capacity increases
1-9 months= Coughing and shortness of breath decrease
1 Year= Heart attack risk halved
10 Years= Lung Cancer risk halved
15 Years= Heart attack risk is similar to that of someone who never smoked
Stop Smoking

17. Tobacco Diseases
Chronic Bronchitis=bronchi are irritated, cilia become useless, tar builds up which results in coughing and excessive mucus
Emphysema=destruction of air sacs (alveoli) in the lungs.
Lung Cancer=persistent cough, repeated bouts of pneumonia *leading cause of cancer deaths
Circulatory System Problems=nicotine makes heart work harder and constricts blood vessels slowing circulation and increasing aging

18. Warning Pictures may be
Smokeless Tobacco
1 Can contains the same amount of nicotine as 60 cigarettes
Sends the same amount of carcinogens into the blood stream
Dip health risks=mouth sores, cancer of the lip, mouth, tongue, damage to teeth, gums, and digestive tract.
Warning Pictures may be
Graphic to some!
