History of mammography 1 Flashcards
Since the introduction of the Radical mastectomy, mammography is the single most important innovation in breast cancer control.
1898
- Breast cancer was the leading cause of death from cancer of a woman between the ages of 39 – 45.
1984
- reported the radiographic appearance of breast cancers and described the mechanism of how breast cancer spread, based on x-ray studies of cancerous breast removed at surgery.
1913
( German Physician) reported the radiographic appearance of breast cancers and described the mechanism of how breast cancer spread, based on x-ray studies of cancerous breast removed at surgery.

The first published radiograph of a living person’s breast
1927
The first published radiograph of a living person’s breast was made by
Kleinschmidt
- mammography was refined to the point of being a reliable clinical tool.
1950s
– the Du Pont Company first introduced high resolution, faster speed x-ray film in combination with an intensifying screen.
1970
- Improved film screen combinations were developed by both KODAK and DU PONT, by this time extremely high- quality mammography image could be produced with very low patient radiation exposure.
1975
– Implement the Breast Cancer Detection Demosntration Project ( BCDDP)
1973
A project were in 280, 000 woman underwent annual screening for breast cancer.
Breast Cancer Detection Demosntration Project ( BCDDP)
The evidences that breast irradiation can increase the breast cancer:
- The population exposed to the atom bomb at Hiroshima and Nagasaki
- A group of women with tuberculosis who received multiple fluoroscopic examination of the chest.
- A group of women who were treated with radiation for postpartum mastitis.
Average exposure according to BCDDP in mammogram using:
Xerogram =
Film-Screen mammogram =
Xerogram = 0.37 rad
Film-Screen mammogram = 0.04 rad
The mammogram is an excellent tool for the detection of breast cancer, but and it also diagnose breast cancer. T OR F?
F. it doesnt diagnose
Women between the ages 40 and 50s should have an annual or biannual mammogram, and women between the ages of 35 and 40 should have baseline mammogram.T OR F?
