  1. Cancer • Cancer-a disease that occurs when abnormal cells grow out of control. • The body is made up of more than 50 trillion cells, both normal and abnormal. • The body’s natural defenses usually destroy abnormal cells, but sometimes they survive and reproduce. • Tumor-group of abnormal cells that form a mass. • Benign tumor-not cancerous and doesn’t spread. • Malignant tumor-is cancerous and may spread to other parts of the body.

  2. Types of Cancer • Breast cancer • Risk factors include: • Family history • Age; more common in women over 50 • Can occur in younger women and men • Important facts: • Breast cancer is the second major cause of cancer death among women.

  3. Types of Cancer • Reproductive Cancers • Risk factors • Age • Family history • Obesity • smoking • Important facts • Females-cervix, ovaries, uterus • Males-prostate gland, testicles

  4. Types of Cancer • Colon and rectum cancer • Risk factors • High-fat, low-fiber diet • Sedentary lifestyle (lack of physical activity) • smoking • Important facts • Cases have declined due to increased cancer screening and better treatments.

  5. Types of Cancer • Leukemia • Risk factors • Not known, may be linked to certain types of radiation and chemicals. • Important facts • Causes a rise in abnormal white blood cells. • Hinders the body’s production of healthy blood cells.

  6. Types of Cancer • Lung cancer • Risk factors • SMOKING!!!! • Important facts • This is the largest cause of cancer death. • Nearly 80% of all cases are related to smoking.

  7. Types of Cancer • Lymphoma • Risk factors • Not known but may be exposure to certain infections. • Important facts • Weakens the immune system, leaving the body more vulnerable to infection.

  8. Types of Cancer • Skin cancer • Risk factors • Sun exposure • Light skin, hair, and eye coloring • Important facts • This is the most common form of cancer in the United States. • Some types of skin cancer are easier to treat than others.

  9. Causes of Cancer • Some cancers can be linked to inherited traits, behavior choices and environmental factors. • Carcinogens-are substances in the environment that causes cancer. • A person must be exposed to a carcinogen for a long period of time for cancer to develop. • Tobacco -minerals/chemicals • Ultraviolet rays from the sun -air/water pollution • Radiation -high fat/low fiber diet

  10. Combating Cancer • Early detection is the key to defeating cancer. • Get regular checkups. • Perform self-examinations. • Look for any unusual changes in you body. • Lumps • Moles changing colors or size

  11. What Doctors Can Do • Surgery-is the primary treatment for may types of cancer. • Doctors remove the tumors and other cancerous cells. • Most effective when cancer is confined to one area of the body. • Used on breast, skin, lung, and colon cancer.

  12. What Doctors Can Do • Radiation therapy-treatment for some types of cancer that uses X-rays or other forms of radioactivity. • Works best when cancer is limited to one area. • Also used to kill any cancer cells that may remain after surgery.

  13. What Doctors Can Do • Chemotherapy-the use of powerful drugs to destroy cancer cells. • Used to stop cancers that have spread throughout the body. • Also used to shrink tumors before surgery is performed.

  14. Side Effects • All of the cancer treatments have side effects. • The destruction of healthy cells. • Nausea • Fatigue • Temporary hair loss

  15. What You Can Do • While there are no guaranteed ways to prevent cancer you can make choices to lower the risk of developing cancer by: • Avoiding tobacco • Take action to detect cancer early • Limit fat intake • Eat more fruits, vegetables, and whole grains. • Go easy on grilled meats • Limit salt intake

  16. What You Can Do • Limit sun exposure • Avoid sun between 10 am and 4 pm UV rays are strongest. • Wear sunscreen at least SPF 15 • Perform self-exams • Breast and testicular monthly • Moles • Asymmetry -Border irregularity • Color -Diameter

  17. What You Can Do • Know the warning signs • Change in bowel or bladder habits. • A sore that doesn’t heal. • Unusual bleeding or discharge. • Thickening or lump in breast or testicles. • Indigestion or difficulty swallowing. • Obvious change in wart or mole. • Nagging cough or hoarseness.
