1. A Guide to Understanding Cancer

2. What is Cancer? Group of more than 100 related genetic diseases
Reference 1
Group of more than 100 related genetic diseases
Can start almost anywhere in the body when abnormal cells undergo uncontrolled cell division due to changes in their DNA
Can form tumors that may invade local tissues and spread to other parts of the body

3. How Does Cancer Start?
Cells become cancerous due to DNA damage, having the genetic information mutated and not fixed—cells keep dividing with the mutation, making it harder to eradicate the whole problem, as now every cell in that area will have the modified DNA

4. How Cancer Spreads
Reference 2
Malignant tumors will invade local tissues and spread to other parts of the body; benign tumors will not
The spread of cancer cells to other places in the body is called metastasis
Cancer cells can travel through blood or lymph to other parts of the body to form new tumors

5. How Common Is Cancer?
About 39.6% of men and women will be diagnosed with cancer during their lifetime, although the rates are higher for men.
It is estimated that there will be more than 1.5 million new cancer diagnoses and more than 589,000 deaths from some form of cancer in the United States this year.
It is expected that new cancer cases will rise from 14 million in 2012 to 22 million within two decades.

6. Major Categories of Cancer
Carcinoma
Sarcoma
Leukemia
Lymphoma
Melanoma
Most common cancer, forms in epithelial cells, ex: adenocarcinoma, basal cell carcinoma, squamous cell carcinoma
Difficult to detect, forms in bone, muscle, fat, blood vessels, other soft tissues
Forms in blood-forming tissue or bone marrow
Form in white blood cells of the immune system, lymph nodes/lymph vessels
Forms in cells that become melanocytes (make melanin), mostly in skin

7. Causes of Cancer Risk of cancer increases with age Lifestyle
Alcohol, tobacco, obesity
Carcinogens in air, water, food, materials
Certain viruses, bacteria, and other parasites
Radiation
Sunlight
Genetics and family history
*Tobacco is the leading cause of cancer and death from cancer
Most common new cases in ages 65-74
Alcohol: the more you drink, the higher the risk
No safe level of tobacco use
UV radiation from sunlight and tanning beds
Mutations in DNA, genetic changes can be inherited, errors in cell division

8. Signs and Symptoms Seven warning signs of cancer:
C: Change in bowel or bladder habits
A: A sore that does not heal
U: Unusual bleeding or discharge
T: Thickening or lump in the breasts or elsewhere
I: Indigestion of difficulty in swallowing
O: Obvious change in a wart or a mole
N: Nagging cough or hoarseness
* Having these symptoms does not necessarily mean you have cancer
It is best to be safe and go see a doctor
Early cancer does not usually cause pain

9. When To See a Doctor If symptoms persist or are severe, see a doctor
No signs and symptoms should be ignored or overlooked
Treatment works best when cancer is found early
It is important to see a doctor periodically as cancer can be found even without symptoms
Preventative checkups are a great idea
Reference 11

10. Prevention Around 1/3 of cancer cases are preventable
Do not smoke or use other tobacco products
Drink alcohol in moderation
Keep a healthy diet
Maintain an ideal weight
Exercise
Minimize exposure to sun and wear sunblock
Smoking: tobacco is one of biggest risk factors—20% of cancer deaths
Diet: more fruit and veggies, less fat and red meat, more fiber
Reference 12

11. Cancer Treatment Surgery Radiation therapy Chemotherapy
Stem cell transplant
Immunotherapy
Hormone therapy
Reference 13
Remove tumors/ cancerous cells
Use high doses of radiation
Use drugs
Restore stem cells of blood (used with radiation and chemotherapy)
Enhance immune system to fight cancer
Cancer uses hormones to progress

12. Treatment Side Effects
Reaction to cancer treatment varies from person to person
Anemia
Appetite/ weight loss
Bleeding and bruising
Urinary problems
Pain
Nausea and vomiting
Hair loss
Fatigue
Edema
Others
Anemia: Not enough red blood cells—causes tiredness, dizziness
Bleeding: From low # of platelets
Edema: excess fluid in tissues, causes swelling
Chemo and radiation have many side effects

13. Figure 1 displays the number of new malignant cancer cases (incidence) and cancer deaths (mortality) in Utah residents in 2010.
•In 2010, 9,233 Utahns were diagnosed with cancer and 2,810 died of cancer. Cancer is the second leading cause of death in Utah and the United States, exceeded only by heart disease.
•Five cancer sites alone account for more than half of all new cancer diagnoses. These include prostate (18.7%), breast (13.9%), melanoma of the skin (8.2%), colon and rectum (7.5%), and lung and bronchus (6.1%) cancers.
•The most common causes of death from cancer in Utah were lung and bronchus (16.3%), breast (9.2%), colon and rectum (8.9%), prostate (7.9%), and pancreas (7.3%). These five sites accounted for nearly 50% of cancer deaths in Utah.
•The number of new cases (214) and deaths (204) from pancreatic cancer were very close in Utah in In contrast, thyroid cancer was diagnosed in 433 Utahns, but caused fewer than 10 death

14. Figure 2 presents the Utah-U. S. incidence rate ratio (IRR)
Figure 2 presents the Utah-U.S. incidence rate ratio (IRR). The IRR was calculated from the five-year, 2006 to 2010, age-adjusted cancer incidence rates in Utah and the United States (excluding Utah). The IRR indicates which cancer sites in Utah were above or below the U.S. age-adjusted incidence rate. This information is important for understanding Utah’s unique cancer burden.
•Utah’s cancer incidence rate was 11% lower than the national rate and is routinely one of the lowest cancer incidence rates in the nation. The age-adjusted incidence rate in Utah from was cases per 100,000 Utahns.
•Utah’s low overall cancer rate is driven in part by the exceptionally low incidence rate of lung and bronchus cancer. The lung and bronchus incidence rate in Utah from was 28.1 cases per 100,000 Utahns, which was a remarkable 57% lower than the national rate.
•In contrast, the incidence rate of melanoma of the skin in Utah was a striking 61% higher than the U.S. incidence rate and was the highest rate in the nation. The age-adjusted incidence rate of melanoma of the skin in Utah from was 31 cases per 100,000 Utahns while the U.S. rate was 19.3 cases per 100,000 U.S residents.

15. Figure 4 presents the annual age-adjusted incidence (new cases) and mortality (deaths) rates for Utah and the U.S. from Monitoring historical changes in rates over time (long-term trends) is important for understanding cancer patterns and the effectiveness of cancer control efforts.
•Cancer incidence has consistently been lower in Utah as compared to the U.S. From incidence rates in Utah rose by a small, but significant 0.9%* per year. This was similar to the pattern seen in the rest of the nation.
•In the late-1980s to the mid-1990s the introduction of prostate-specific antigen (PSA) screening impacted cancer incidence rates across the nation. A sharp rise and decline in incidence is visible.
•Utah experienced a significant increase in cancer incidence rates of 2.3%* per year from However since 1999, cancer incidence rates in Utah have remained fairly flat with no significant increase or decrease. In contrast since 1999, national cancer incidence rates have fallen by 0.5%* annually.
•Cancer mortality rates in Utah have remained below U.S. rates for nearly forty years. For decades mortality rates nationwide remained fairly stable. However since 1998, mortality rates in Utah have decreased by 1.6%* per year, while national rates have fallen at a slower rate of 1.5%* per year.
