A 65-year-old female asked:

Is it true that mammograms have 100 percent more radiation than a chest x-ray?

Not exactly: The exposure from the average chest xray is 0.1msv (milliserverts). The mammogram is 0.4 msv. A ct of the chest is 7 msv. The risk for the chest xray is minimal to cause cancer and very low for mammogram. Depending on how these terms of minimal and very low are defined you could think that the cancer risk was much greater. For both itis very very small cancer risk. The benefit are much greater.
Dr. Timothy Goggins

No: It is true that mammograms do give off radiation, as they are an x-ray. The likelihood of receiving excessive radiation from a mammogram is extremely low. It would require a minimum of 100 x-rays to get a significant amount of radiation.
Dr. Hosea Mcadoo
Radiology 55 years experience
No: Modern mammography delivers a much lower dose than in the past and what's more the dose is delivered only to the breast.
