HISTORY OF MAMMOGRAPHY

First proposed in 1924

Article published in 1930

1960’s Robert Egan considered the “Father of Mammography”

Also 1960’s Charles Gros developed 1st dedicated Mammo unit (Dose 8-12 rads)

1971 Xeroradiography (Dose 2-4rads)

IMPORTANT FACTS ABOUT MAMMOGRAPHY

Mammography is the most sensitive and accurate screening modality available for detecting early breast cancer.

It is not always diagnostically specific.

It complements but cannot replace regular physical exams and BSE.

STATISTICS: Breast Cancer

Most common cancer among women

Second leading cause of cancer deaths

ACS projects 212,920 new cases for women in 2006

Of these, 40,970 expected to die.

STATISTICS

One of eight women in the U.S. will develop breast cancer.

Approximately 50% of cancers detected at a screening are impalpable

9% of breast cancers are not detected by Mammography.

WHAT ABOUT MEN?

An estimated 1720 cases expected in men for 2006.

Approximately 460 men will die.

FREQUENCY

Age 35 for baselineNational Institutes of Health (NIH) states screening ages 40-49 every 1-2 years; every year over 50 ACS recommends every year after age 40Patients with strong family histories should start 10 years prior to age of family member with cancer.

LUMP SIZE

Average size lump found by occasional BSE is 2.5cm (1”)Ave lump found by Mammography is .5 cm (1/4”)(5yr survival 95%)On average, lesions detected by mammography are 8 years old.By 2 cm nodes are involved in 50-60% of the cases.5 year survival rate is 60%

DOSE

1969Patient dose 8-12 rads

1971Xeroradiography introducedDose 2-4 rads

1986 ACR recommends <300mrad per single view with grid

19944 view =.15 rads or 150mradsDental = 400 mradCA Therapy =500 rads

COMPARISON OF DOSE TO DAILY LIFE

The risk of death from developing breast cancer due to radiation received from a single mammographic examination is equal to the risk of:

Traveling 80 miles by air

Traveling 10 miles by car

Smoking 1/8 of one cigarette

11/2 minutes of mountain climbing

3 minutes of being a man age 60

Eating 40 TBSP peanut butter

EXPERIENCE

INITIALCertification or 40 hours of Mammography training.

25 supervised exams

CONTINUING15 CE every triennium

100 exams every year

REWARD

Relaxed environment

One on one patient contact

Saving lives
