Seven Mammogram Myths

Annual mammograms are an essential part of a woman’s health. But myths, rumors and misinformation deter some women from making the appointment.

Here are seven of the most common mammogram myths and the facts to set the record straight:

Myth #1: I don’t have any symptoms of breast cancer or a family history, so I don’t need to worry about having an annual mammogram.

Fact: The American College of Radiology recommends annual screening mammograms for all women over 40, regardless of symptoms or family history. Early detection is critical. If you wait to have a mammogram until you have symptoms of breast cancer, the cancer may be more advanced. According to the American Cancer Society, early-stage breast cancer has a five-year survival rate of 99 percent. Later-stage cancer has a survival rate of 27 percent.

Myth #2: A mammogram will expose me to an unsafe level of radiation.

Fact: While a mammogram does use radiation, it is a very small amount and is within the medical guidelines. A mammogram is safe as long as the facility you go to is certified by the regulating agencies.

Myth #3: A 3D mammogram is the same as a traditional mammogram.

Fact: Three-dimensional mammography, or tomosynthesis, is the most modern screening and diagnostic tool available. A 3D mammogram displays more images of the breast and in thin sections of breast tissue. 3D mammograms provide us greater clarity and the ability to determine the difference between overlapping normal tissue and cancer. With 3D mammography, the data show a 40 percent increase in detecting early cancer and a 40 percent decrease in false alarms or unnecessary recalls from screening.

Myth #4: If I have any type of cancer in my breast tissue, a screening mammogram is guaranteed to find it.

Fact: While annual mammograms are very important for women, there are limitations. This is mostly due to dense breast tissue that can hide cancer. Normal breast tissue can both hide a cancer and mimic a cancer. In addition to an annual mammogram, other imaging methods including a breast ultrasound and a breast MRI can be used for women with dense breast tissue.

Myth #5: I had a normal mammogram last year, so I don’t need another one this year.

Fact: Mammography is detection, not prevention. Having a normal mammogram is great news, but it does not guarantee that future mammograms will be normal. Having a mammogram every year increases the chance of early detection.

Myth #6: My doctor didn’t tell me I needed a mammogram, so I cannot schedule an exam.

Fact: You do not need your doctor to write you a prescription or complete an order for you to have a screening mammogram. The recommendation is that if you are a woman 40 or older, you should have a mammogram every year. Women can self-refer to make an appointment for their annual mammogram.

Myth #7: Mammograms are always painful.

Fact: Sibley Memorial and Suburban Hospitals both have the latest technology to provide a more comfortable experience with less pain. This involves a curved compression surface that mirrors the shape of a woman’s breast. The rounded surface improves comfort by reducing pinching and evenly distributing pressure over the entire breast.
