How is the Breast DesignedThe 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.

Types of Breast CancerDuctal CarcinomaDuctal 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

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.

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

Risk Factors for Breast CancerObesityDiet: Fat
Alcohol
Lack of Physical Activity ; StressRadiation ExposureHistory 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

Screening For Breast Cancer
A Good Breast Health Plan• Self Awareness (Monthly
Self Exams) (BSE)
• Clinical Breast Examination (CBE)
• Mammograms
![Page 13: breastcancerppt-121008024558-phpapp01](https://reader036.fdocuments.in/reader036/viewer/2022070419/55cf97f0550346d033948d19/html5/thumbnails/13.jpg)
Screening Average-size lump found by woman practicing occasional breast self-exam (BSE)

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
![Page 15: breastcancerppt-121008024558-phpapp01](https://reader036.fdocuments.in/reader036/viewer/2022070419/55cf97f0550346d033948d19/html5/thumbnails/15.jpg)
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
![Page 16: breastcancerppt-121008024558-phpapp01](https://reader036.fdocuments.in/reader036/viewer/2022070419/55cf97f0550346d033948d19/html5/thumbnails/16.jpg)

Why don’t more women practice BSE
• Fear• Embarrassment• Youth• Lack of knowledge• Too busy, forgetfulness
![Page 18: breastcancerppt-121008024558-phpapp01](https://reader036.fdocuments.in/reader036/viewer/2022070419/55cf97f0550346d033948d19/html5/thumbnails/18.jpg)
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
![Page 19: breastcancerppt-121008024558-phpapp01](https://reader036.fdocuments.in/reader036/viewer/2022070419/55cf97f0550346d033948d19/html5/thumbnails/19.jpg)
MammographyX-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
![Page 20: breastcancerppt-121008024558-phpapp01](https://reader036.fdocuments.in/reader036/viewer/2022070419/55cf97f0550346d033948d19/html5/thumbnails/20.jpg)
Women (asymptomatic) 40 years of age and older should have a
MAMMOGRAM every year.
