  1. CANCER Ms. Kelly 8th Grade Health

  2. www.thon.org • THON 2013 Promo Video • ELI’S STORY • Hatters Play 4 A Cure

  3. Oncology • Study and treatment of cancer • Over 100 types

  4. MOST COMMON TYPES

  5. New Cases vs. Death Rates

  6. Definition • Groups of abnormal cells that multiply out of control • Due to something wrong with size, shape, or DNA/function

  7. Tumors • Group of cells that grow together to form a mass • No apparent function • BENIGN: grows harmlessly without spreading • MALIGNANT: Abnormal cells that spread to other parts of the body (CANCEROUS!)

  8. BENIGN MALIGNANT

  9. Journal: • React the following statistics. How do they make you feel? Are you surprised, do they shock you, etc.? • In 2014, about 585,720 Americans are expected to die of cancer (almost 1600 people per day). It is the second most common cause of death in the US. • The 5-year survival rate for all cancers between 2003 and 2009 is 68% (up from 49% in the 70s). Source: American Cancer Society

  10. Metastasis • Spreading of cancer from localized area to other parts of the body via lymph and blood

  11. Biopsy • Removal of a small amount of tissue for examination under a microscope

  12. JOURNAL: • You completed the “Faces of Cancer” activity last class… explain what you learned from the activity. Consider: • Trends, if any, you noticed (re: family history, age, etc.) • Risk factors (certain ones more common than others) • Etc…

  13. ENVIRONMENTAL CARCINOGENS: cancer-causing agents Alcohol Smoke/chewing tobacco Radiation (X-Rays) Nitrites (smoked meats) Sun (UV Rays) BIOLOGICAL Family tendencies Risk increases with age Others biological causes Asbestos Radon Pesticides Additives Causes of Cancer

  14. Latency Period • Period of time it takes for the cancer to develop • Time of exposure to time symptoms appear • Can be 20-30 years before the cancer is detected

  15. Avoid tobacco products Avoid excess alcohol consumption High fiber/low fat diet Avoid stress Avoid prolonged exposure in the sun (SPF 15 or higher) Avoid too much radiation Physical check-ups/ self-exams Prevention

  16. Cancer Fighting Foods • All dark, leafy, green veggies, cruciferous veggies (broccoli, cauliflower, cabbage) • Whole grains (whole wheat, brown rice) • Vitamins C and E • Soy, beans, peas • All fruits • Olive oil • Salmon • Green tea

  17. Journal: If you could go anywhere in the world, where would you go and why??

  18. Change in bathroom habits A sore that doesn’t heal Unusual bleeding, bruising, or discharge Thickening or lump Indigestion or difficulty swallowing Obvious change in wart or mole Nagging cough or hoarseness Unusual weight loss/unusual headaches Warning Signs

  19. Treatments • Surgery—removal of tumor • Cryosurgery is used for mouth and skin cancers (liquid nitrogen)

  20. Treatments (con.) • Chemotherapy—50 different drugs (IV, pills, injection) • Chemicals destroy cancer cells by interfering with DNA without harming too many normal cells • Side effects: nausea, hair loss, rashes

  21. Treatments (con) • Radiation—Cancer cells more sensitive than normal cells • Most sensitive areas: bone marrow where blood cells are made (sternum) and pelvic area where reproductive organs located

  22. Remission • Period of time when person is symptom- free • Permanent remission: 5 years with no reoccurrence

  23. Melanoma • Most serious form of skin cancer • ABCDE’s of Melanoma Detection • A: Asymmetry • B: Border • C: Color • D: Diameter • E: Elevation
