Malignant – CAPABLE OF INVADING SURROUNDING STRUCTURES, PRODUCING
INVASIVE TUMORS OR UNCONTROLLED GROWTH
Tumor – A MASS OF TISSUES THAT SERVE NO PHYSIOLOGICAL PURPOSE
Free Radicals – DETRIMENTAL, PARASITIC CELLS THAT TAKE ENERGY FROM OTHER
CELLS, WHICH CAN RESULT IN THOSE HEALTHY CELLS BEING TAKEN OVER BY
CANCEROUS CELLS.
Metastasis – THE SPREADING OF CANCER CELLS WHICH OCCURS DUE TO THE
LACKOF CELLULAR COHESIVENESS.
Oncologist – A SPECIALIST IN THE STUDY OF TUMORS
Chemotherapy – THE TREATMENT OF CANCER WITH CHEMICALS THAT SELECTIVELY
DESTORY CANCEROUS CELLS.

cover external body surfaces
(organs, skin, nerves, and

Bone, blood, and connective
tissue
Blood and blood forming tissue
(bone marrow)
CANCER PREVELANCE AND PREVENTION
1 in 2 men will develop cancer in their life
1 in 3 women will develop cancer in their life
According to the ACS(AMERICAN CANCER SOCIETY)


90% of skin cancer is preventable
87% of LUNG CANCER can be prevented by avoiding EXPOSURE to smoke
LUNG CANCER
163,000 deaths a year
RISK FACTORS:


SMOKING
EVIRONMENTAL POLLUTANTS
o EVIRONMENTAL TOBACCO SMOKE (ETS)
 Mainstream – smoke that comes directly off the burning end of a
CIGARETTE/CIGAR
 SECONDHAND SMOKE - smoke that has traveled through an
individual’s respiratory system already.
DETECTION:




16% of cases are detected before spreading
PERSISTANT COUGH
CHEST PAIN
REOCCURRING BRONCHITIS
COLON & RECTAL CANCER
**Considered the 2nd leading cause of cancer deaths
DETECTION & TREATMENT


90% survival rate if detected EARLY
63% OVERALL survival rate
BREAST CANCER
MOST COMMON CANCER IN WOMEN
1 in 7 women will develop breast cancer
1 in 30 women will die from breast cancer
RISK FACTORS






Age
o Risk doubles every 5 years between the ages of 35-45
GENETICS
Early Menstrual Cycle
Women with no CHILDREN
Obesity
Alcohol use
PREVENTION



Diet
Mammography
o Every year after the age of 40
Activity Levels
o Women who exercise are 37% less likely to develop breast cancer
PROSTATE CANCER
Most common cancer in men (300-thousand men die a year)
DETECTION (Annual screenings starting at the age of 50)

Symptoms
o CHANGE IN URINARY FREQUENCY
o Painful URINATION
o BLOOD in urine
CERVICAL CANCER
230-thousand WOMEN die worldwide
RISK FACTORS



Infection with HUMAN PAPILLOMAVIRUS (HPV)
Smoking
Herpes
PREVENTION


SEXUAL ABSTINENCE - choosing not to engage in any form of sexual contact
Pap Tests (Annual tests ages 18-65)
TESTICULAR CANCER
RISK FACTORS

FAMILY history
PREVENTION

SELF EXAMS
DETECTING CANCER

FINAL THOUGHTS
2 main practices of preventing cancer causing deaths are:
1. LIFESTYLE CHOICES/HABITS
