What Is Cancer?
Cancer
is a large group of diseases (over 200) characterized by uncontrolled growth and spread of abnormal cells.*
*American Cancer Society, Cancer Facts and Figures 2005
Normal Cells Vs. Cancer Cells
Cancer cells: Lose control over growth and multiplication
Do not self-destruct when they become worn out or damaged Crowd out healthy cells
Growth of Cancer Cells
Cancer cells reproduce every 2-6 weeks.
2-6 weeks
2-6 weeks
Size of cancer cells: One million cancer cells = head of a pin
One billion cancer cells = a small grape 230 = 1,073,741,824 = 1 billion cells
2-6 weeks
Signs and Symptoms of Cancer
Change in bowel habits or bladder functions Sores that do not heal Unusual bleeding or discharge Lumps or thickening of breast or other parts of the body Indigestion or difficulty swallowing Recent change in wart or mole Persistent coughing or hoarseness
Types of Cancers
Carcinomas (cells
that cover internal and external body surfaces)
Leukemia
(Blood Cells)
Lung Breast
Lymphomas
(Lymph nodes &tissues)
Colon
Bladder Prostate (Men)
Sarcomas Cells in supportive tissues – bones & muscles
What Causes Cancer?
Lifestyle Environment
Family History
Lifestyle Risks
Smoking Diet high fat and low in fruits and vegetables
Lack of exercise
Unprotected exposure to the sun, (UV) rays Obesity
Environmental Risks
Second hand smoke Air pollution Industrial pollution Chemical exposures
Inherited Risks
Less than 15% of cancers are inherited Gene mutations are linked to some inherited cancers Cancers that may be caused by inherited gene mutations are: Colon cancer Breast cancer Ovarian Prostate cancer Skin cancer
Screening Tests and Self-exams
Screening tests: Colon Breast Cervical Prostate Self-exams: Testicular Skin
Why Screening Tests?
The treatment of cancer is most successful when the cancer is detected as early as possible, often before symptoms occur.
Colon Cancer
Most colon cancers start as a polyp
Removing polyps can prevent colon cancer
• A polyp
• Advanced
bleeding cancer
Colon Cancer Screening Guidelines
Age of 50 and older; younger if there is a family history Yearly fecal occult blood test (FOBT) or Flexible sigmoidoscopy every 5 years or Yearly FOBT and sigmoidoscopy every 5 years or Double-contrast barium enema every 5 years or Colonoscopy every 10 years
Of the options above ACS prefers yearly FOBT and Sigmoidoscopy every five years
Breast Cancer Screening Guidelines
Yearly mammograms starting at age 40 and continuing for as long as a woman is in good health. Clinical breast exams (CBE) should be part of a periodic health exam, about every three years for women in their 20s and 30s and every year for women 40 and over.
Breast Cancer Screening Guidelines
Women should report any breast change promptly to their health care providers. Breast self-exam (BSE) is an option for women for women starting in their 20s. Women at increased risk (e.g., family history, genetic tendency, past breast cancer ) should talk with their doctors about the benefits and limitations of starting mammography screening earlier, having additional tests (e.g., breast ultrasound or MRI), or having more frequent exams.
Cervical Cancer Screening Guidelines
Annual pap testing should begin with the onset of sexual activity or at age 18 Investigate pros & cons of new HPV vaccine Pap testing should continue less frequently at the discretion of the medical provider and patient after three or more annual tests have been normal
Prostate Cancer Screening Guidelines
Men should speak to their doctor about the pros and cons of prostate cancer screening
Both prostate specific antigen (PSA) and digital rectal examinations (DRE) are recommended for men over 50 and who choose to undergo screening for prostate cancer
Testicular Cancer Screening Guidelines
Doctors agree that examination of a man’s testicles is an important part of a general physical exam. It is recommended that a testicular exam be conducted during routine cancer-related checkups.
It is believed that it is important to make men aware of testicular cancer and that any unusual mass should be evaluated by a health care provider immediately.
Skin Cancer
A B C D
The ABCD’s of melanoma (skin cancer):
Asymmetry: one half is not like the other Border: the edges are jagged or irregular Color: the color is varied, tan, red, black ect Diameter: the diameter is larger than 8mm (the top of a pencil eraser
Skin Cancer Prevention
It is important to:
Protect your skin with hats, long sleeves and sunscreen Do a self examination of your skin monthly Become familiar with any moles, freckles or other abnormalities on your skin Check for changes once a month. Show any suspicious or changing areas to your health care provider.
Good News!
Other Ways to Reduce the Risks of Developing Cancer…
How Far Have We Come ?
Five year survival rate: 1913 - 10%
2003 - 66% Advances in cancer research continue
The Fight Will Continue Because…in 2007
Cancer is the second leading cause of death in Utah and the nation
7660* Utahns diagnosed 2690* Utahns will die 7 Utahns die of cancer every day
*American Cancer Society, Cancer Facts and Figures 2007
Avoid Smoking or Chewing Tobacco
Cigarette smoking is the leading cause of preventable death in the US Second hand smoke affects everyone
Fruits and Vegetables Decrease Cancer Risks
Cancer rates could decline by up to 20% if everyone consumed 5 fruits and vegetables a day!* Cancer fighting substances:
*American Institute for Cancer Research, 1998.
Antioxidants Dietary fiber Carotenoids Flavenoids
Limit Alcohol to No More Than
Men – 2 drinks per day Women - 1 drink per day
Reduce Your Skin Exposure to the Sun
Limit time outside, between 10 a.m. & 4 p.m. Wear protective clothing. Use wide-brimmed hats and sunglasses. Prevent sunburns, especially for children under 18. Use waterproof sunscreen of SPF 15 or higher. Reapply as directed.
Avoid tanning beds.
