Can a mammogram detect cancer early?

A mammogram can often find or detect breast cancer early, when it’s small and even before a lump can be felt. This is when it’s easiest to treat. What are the main uses of mammograms? A screening mammogram is used to look for signs of breast cancer in women who don’t have any breast symptoms or problems.

How accurate is a mammogram?

But mammograms have their limits. For example, they aren’t 100% accurate in showing if a woman has breast cancer: A false-negative mammogram looks normal even though breast cancer is present. A false-positive mammogram looks abnormal even though there’s no cancer in the breast.

What are the limitations of a mammogram?

For example, they aren’t 100% accurate in showing if a woman has breast cancer: A false-negative mammogram looks normal even though breast cancer is present.

How do mammograms work?

Mammograms are done with a machine designed to look only at breast tissue. The machine takes x-rays at lower doses than the x-rays done to look at other parts of the body, like the lungs or bones. The mammogram machine has 2 plates that compress or flatten the breast to spread the tissue apart. This gives a better quality picture and allows less radiation to be used.


How much radiation does a breast x-ray machine use?

On average the total dose for a typical mammogram with 2 views of each breast is about 0.4 millisieverts, or mSv. (A mSv is a measure of radiation dose.)

By Joe Rojas-Burke June 30, 2020 Portland, Oregon. (Getty Images) About 20% to 30% of women with breast cancer have tumors that are missed by mammogram screening. And these interval breast cancers – discovered between routine mammograms – seem to be more lethal than those detected by screening. A new study by Oregon researchers has found …


How long does it take for cancer to appear after a mammogram?

A new study by Oregon researchers has found that survival is worse only if the interval cancer appears within one year after a mammogram that did not detect cancer. “One would think that the longer you are from your negative screen, the larger and deadlier the tumor would be.


How many interval cases of breast cancer are there?

About two-thirds of the breast cancers were detected by screening, and one-third were discovered between screenings. Among the 1,050 interval cases, 324 were diagnosed within the first year after a negative mammogram, and 726 interval cases were diagnosed later, one to two-and-a-half years after a negative mammogram.


What are the differences between interval cancer and screen cancer?

The early interval cancer cases had significantly larger tumor size and a higher proportion of them had lymph node involvement and lobular tissue type compared to screen-detected cancers.

Is there a difference between interval cases diagnosed after the first year and screen diagnosed after one year?

But there was no measurable difference in breast-cancer-specific mortality between interval cases diagnosed after the first year compared with screen-detected breast cancers.


Is interval cancer more advanced than screen cancer?

It’s been known for years that interval breast cancers tend to be diagnosed at a more advanced stage than screen-detected cancers. Interval cases have also been associated with two to three times higher risk of death from breast cancer compared with screen-detected cases. But previous studies have left unknown whether the timing of the interval cancer makes a difference in how aggressively it behaves. To find out, Irvin and Zhang turned to the Women’s Health Initiative, a national study that enrolled participants from 1993 to 1998 and has continued to track their health over the years.

Overdiagnosis and Overtreatment

  • Screening mammograms can often find invasive breast cancer and ductal carcinoma in situ (DCIS, cancer cells in the lining of breast ducts) that need to be treated. But it’s possible that some of the invasive cancers and DCIS found on mammograms would never grow or spread. (Finding cancers that would never cause problems is called overdiagnosis.) Th…

Radiation Exposure

  • Because mammograms are x-ray tests, they expose the breasts to radiation. The amount of radiation from each mammogram is low, but it can still add up over time. For more on this, see Mammogram Basics.
