Radiation due to mammography can cause carcinoma

USG is better than mammography
Mammography Soft tissue radiographs are taken by placing the breast in direct contact with ultrasensitive film and exposing it to low-voltage, high-amperage x-rays . The dose of radiation is approximately 0.1 cGy and, therefore, mammography is a very safe investigation. The sensitivity of this investigation increases with age as the breast becomes less dense. In total, 5% of breast cancers are missed by population-based mammographic screening programmes; even in retrospect, such carcinomas are not apparent. Thus, a normal mammogram does not exclude the presence of carcinoma. Digital mammography is being introduced, which allows manipulation of the images and computer-aided diagnosis. Tomo-mammography is also being assessed as a more sensitive diagnostic modality. Ref: Bailey and love 27th edition Pg no : 864
