Oncology
  • Study and treatment of cancer
  • Over 100 types
definition
Definition
  • Groups of abnormal cells that multiply out of control
  • Due to something wrong with size, shape, or DNA/function
tumors
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!)

journal
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).

metastasis
Metastasis
  • Spreading of cancer from localized area to other parts of the body via lymph and blood
biopsy
Biopsy
  • Removal of a small amount of tissue for examination under a microscope
journal1
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…
causes of cancer
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
latency period
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
prevention
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
cancer fighting foods
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

If you could go anywhere in the world, where would you go and why??

warning signs
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
treatments
Treatments
  • Surgery—removal

of tumor

    • Cryosurgery is used

for mouth and skin

cancers (liquid

nitrogen)

treatments con
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

treatments con1
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
remission
Remission
  • Period of time when

person is symptom-

free

  • Permanent remission:

5 years with no

reoccurrence

melanoma
Melanoma
  • Most serious form of skin cancer
  • ABCDE’s of Melanoma Detection
    • A: Asymmetry
    • B: Border
    • C: Color
