How Much Radiation In A Mammogram

Lets look at the numbers. A mSv is a measure of radiation dose.

Using a standard measure of radiation dose milliSievert mSv the total dose for a screening mammogram is about 04 mSv.

How much radiation in a mammogram. A single chest x-ray exposes the patient to about 01 mSv. While theres no question that radiation exposure increases the risk of breast cancer the risk is highest when exposure occurs at a relatively young age. According to the American Cancer Society 1 a typical screening mammogram the type most patients are recommended to have annually uses only 04 mSv.

When the amount of radiation from a CT scan is added to that received from dental x-rays chest x-rays mammograms tests performed for other medical reasons and those done in the past its easy for an individual to reach or surpass the 100 mSv mark. This doesnt tell us much about the risk for the average woman who follows recommendations to have an annual mammogram every year beginning at age 40. This is about the same amount of radiation people are exposed to naturally over the course of about 10 days.

Studies have linked high doses of ionising radiation 50mSv to an increased risk of cancer. Mammograms expose your body to very high levels of radiation some even speculate radiation that is 1000 times greater than a chest x-ray. With mammography youre looking at four times the radiation exposure.

On average the total dose for a typical mammogram with 2 views of each breast is about 04 millisieverts or mSv. Living cells can be damaged by X-rays. A mSv is a measure of radiation dose The radiation dose from 3D mammograms can range from slightly lower to slightly higher than that from standard mammograms.

Mammograms dont expose you to much more radiation than a traditional chest X-ray and the risk posed by a single scan is extremely small. Despite all the concern about mammogram radiation levels the simple fact is that doses are extremely low. On average the total radiation dose for a typical mammogram with two views of each breast is about 04 millisieverts or mSv.

The total dose of radiation received during a mammogram is 4 mSv milliSievert a standard measure of radiation doses. However the risk is extremely low with the radiation dose you will receive from a mammogram. A dose of radiation received during a CT scan is between 3 mSv and 10 mSv.

This includes two views of each breast. These four images are equal to one rad. Radiation is measured in millisieverts mSv.

To put that number in perspective people in the US are typically exposed to an average of about 3 mSv of radiation each year from background sources such as natural surroundings. A mammogram exposes a woman to 04 mSv or about the amount a person would expect to. Mammograms require very small doses of radiation.

Although the potential benefits of mammography nearly always outweigh the potential harm from the radiation exposure women should talk with their health care providers about the need for each x-ray. The total dose of background radiation an average American receives in a year is 3 mSv. Radiation in a mammogram is actually concentrated over a smaller area compared to a chest x-ray and four images are taken for each breast.

9 Its been theorized that ionizing radiation mutates cells and the mechanical pressure can spread cells that are already malignant as can biopsies. To put in perspective Americans are normally exposed to 3 mSv of radiation each year just from their natural surroundings. The risk of harm from this radiation exposure is low but repeated x-rays have the potential to cause cancer.

With a chest x-ray youre looking at a level of 010 mSv of radiation exposure.
