Radiation dose of a digital mammogram: 0.7 msv
Normal background radiation dose: 2.4 msv
Your exposure to daily background radiation is nearly 4x what you get from a digital mammo.
This is like the difference between standing outside in the sun waiting for the bus vs. standing in a dark room while someone shines a flashlight in your face. What's the sunburn risk? I don't get a sunburn waiting for a bus. Someone with severe light sensetivity will get sunburned from a flashlight.
Your exposure is even higher if you live at high elevation or where there are high radon concentrations in the ground or groundwater. The background radiation in Denver CO is higher than what the gov't deems safe. If Denver followed the lowest safe dose reccommendations set by the government, it would be evacuated as dangerously radioactive. Yet Denver has an extraordinarily low cancer rate.
Women with a genetic tendency to develop cancers have a genetically moderated problem in which their bodies don't correct the normal everyday damage/rogue cell we all experience every single day. Every single day of your life, your body is killing mutated cells. (apoptosis) You have "cancer" in your body at all times. Every moment.
Women whose bodies don't recognize damaged/mutated cells as well as everyone else will have more cells slip through the cracks. If those mutated cells get a foothold, they will become a tumor. Younger tissue has a higher radiosensitivity, meaning it is more susceptible to damage from any source of radiation. Cigarettes. Airplane rides. Trips to Denver. Clutching a book (paper is radioactive) to your bosom. Even though mammo radiation is much less than background radiation, most doctors will tell younger women with a history of poor apoptosis control to have breast MRI instead until they are older.
Of 1,000,000 women getting mammograms over their lifetime, there will be an estimated 2-10 tumors induced by the radiation (which are found in the next mammo and treated). 1,000,000 lifetimes of mammograms saves 1,000 lives.
