2  Cancer- uncontrollable growth of abnormal cells  Body’s cells are constantly growing and dividing  Most new cells are normal but some are not

3  Tumor- Abnormal mass of tissue that has no natural role in the body  Some are benign- noncancerous  Do not spread  Can be harmful if they interfere with normal body functions  Ex block blood supply

4

5  Tumors that are malignant, cancerous, spread to other tissues and spread through blood and lymph  Metastasis- the spread of cancer from the point where it started to other parts of the body  Cancer cells can kill normal body cells  They compete for nutrients with the body’s cells

6  Lymphomas- cancers of the immune system  Leukemias- cancer of blood forming organs  Carcinomas- cancer of glands and body lining  Includes skin and line of digestive tract  Sarcomas- cancer of connective tissue  Bones, ligaments, and muscle

7

8  Most common organs affected are Skin, Breast, Prostate, Lung, Colon, Mouth, Cervix

9  A faulty gene may be inherited (5-10% of caner is inherited)  Majority of cancer is caused by exposure to risk factors  Carcinogen- cancer causing substance  Ex cig. Smoke and ultraviolet rays

10

11  Tobacco use is the major cause of cancer deaths and the most preventable  Second hand smoke  Also increases risk of bladder, pancreas, and kidney cancer  43 different carcinogens have been identified in tobacco and tobacco smoke

12

13  Smokeless tobacco- causes oral cancer which affects the lips, mouth, and throat  Kills 1 person every hour

14  Human Papillomavirus (HPV) causes cervical cancer  Hepatitis B causes liver cancer  Reduce risk of these by abstaining from sexual contact

15  Diets high in fat and low in fiber linked with cancer  Fats make colon cells divide more rapidly which increases risk of cancer cells  Fiber speeds the movement of waste through the intestines so carcinogens have less time to act on cells

16  UV rays from sun or tanning bed= main cause of skin cancer  A tan is the body’s response to being injured by UV rays  Avoid tanning beds!  Limit time in the sun if possible esp. between 10:00 AM- 4:00 PM  When outside where sunscreen or long sleeves

17

18  Pay attention to changes to skin  ABCDs of melanoma  Asymmetry (an imaginary line drawn through center of a mole does not produce matching halves)  Border Irregularity- Suspect moles have irregular edges (not smooth)  Color- intensely black, blush tint, or uneven color  Diameter- wider than a pea

19

20  Abstaining from sexual contact  Be physically active  Eat nutritious foods- fruits, vegetables, fiber, low in fat  Protect skin from UV rays  Avoid tobacco and alcohol (increases risk of stomach and mouth cancer)  Be aware of warning signs

21  Changes in bowel habits (loose stools or constipation)  Sore throat that does not heal  Unusual bleeding or discharge  Lump in breast  Difficulty swallowing  Obvious change in moles  Nagging cough or hoarseness

22  Early detection of cancer is most critical factor in successful cancer treatment  Self examination  Medial screening  Biopsy- the removable of a small piece of tissue for examination to determine if cancer was present

23

24  Depends on type of cancer of how much it has spread  Surgery- removes cancerous tumors  Radiation therapy- radioactive rays kills cells and shrinks cancerous mass  Chemotherapy- uses chemicals to destroy the cells  Immunotherapy- activates immune system to recognize cancer cells and destroy them

25

26

27  Hormone Therapy- using medicine that interferes with the production of hormones  Remission- a period of time when symptoms disappear  When cancer responds to treatment  Can reoccur
