2. Breast Cancer Facts
2nd leading cause of death
2nd most common cancer
Incidence increases with age
All women are at risk
3. How is the Breast Designed
The breasts sit on the chest
muscles that cover the ribs.
Each breast is made of 15 to 20
lobes.
Lobes contain many smaller
lobules.
Lobules contain groups of tiny
glands that can produce milk.
Milk flows from the lobules
through thin tubes called ducts to
the nipple.
The nipple is in the center of a
dark area of skin called the areola.
Fat fills the spaces between the
lobules and ducts.
4. Types of Breast Cancer
Ductal Carcinoma
• Originate in ducts that carry milk to nipples
• If cancer confined to duct = in situ (DCIS)
• Usually found on mammogram
• If moved beyond duct = invasive or infiltrating
Lobular Carcinoma
rare
5. What causes Breast cancer
• Breast cancer is always caused by a genetic
abnormality (a “mistake” in the genetic material).
However, only 5-10% of cancers are due to an
abnormality inherited from your mother or father.
About 90% of breast cancers are due to genetic
abnormalities that happen as a result of the
aging process and the “wear and tear” of life in
general.
6. Risk Factors for Breast Cancer
Gender: female (1% males)
Race: more common in whites
Age: increases as a woman gets older.
Relative : (mother or sister)
Menstrual history :early on set
late menopause
Childbirth: first child After the age of 30
or having no children at all
Pregnancy and breastfeeding are protective against breast cancer
7. Risk Factors for Breast Cancer
Obesity
Diet: Fat
Alcohol
Lack of Physical Activity ; Stress
Radiation Exposure
History of cancer: breast, uterus, cervix, ovary
Hormones: estrogens in Hormone replacement
therapy & Birth control pills
Genetics : certain conditions that are inheritated
> 70% have no risk factors

12. Screening For Breast Cancer
A Good Breast Health Plan
• Self Awareness (Monthly Self
Exams) (BSE)
• Clinical Breast Examination
(CBE)
• Mammograms
13. Screening

14. Breast Self Examination (BSE)
• Opportunity for woman to
become familiar with her
breasts
• Monthly exam of the
breasts and underarm area
• May discover any changes
early
• Begin at age 20, continue
monthly
15. When to do BSE
• Menstruating women- 5 to 7
days after the beginning of
their period
• Menopausal women -
same date each month
• Pregnant women –
same date each month
• Takes about 10 minutes
• Perform BSE at least
once a month
• Examine all breast tissue
17. Why don’t more women practice BSE
• Fear
• Embarrassment
• Youth
• Lack of knowledge
• Too busy, forgetfulness
18. Clinical Breast Examination
• Performed by doctor or
trained nurse practitioner
• Annually for women over
40yrs
• At least every 3 years for
women between 20 and
40 yrs
• More frequent
examination for high risk
patients
19. Mammography
X-ray of the breast
Has been shown to
save lives in patients
50-69
Data mixed on
usefulness for patients
40-49
Normal mammogram
does not rule out
possibility of cancer
completely
20. Women (asymptomatic)
40 years of age and
older should have a
MAMMOGRAM every
year.
21. Treatment for Breast Cancer
• Surgery
• Radiation Therapy
• Chemotherapy
• Hormonal Therapy
26. Prognosis after Breast Cancer
5-Year 10-Year Survival
Survival (%) (%)
Stage 0 95 90
Stage I 85 70
Stage II 70 50
Stage III 55 30
Stage IV 5 2
