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.
Types of Breast CancerDuctal 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 infiltratingLobular Carcinomarare
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.

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

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
Mammography X-ray of the breastHas been shown tosave lives in patients50-69 Data mixed onusefulness for patients40-49 Normal mammogramdoes not rule outpossibility of cancercompletely
Women (asymptomatic) 40 years of age and older should have a MAMMOGRAM every year.
