Should I Worry About Needing Follow Up After My Mammogram?

Worry is understandable. You were probably expecting the standard letter in the mail saying your mammogram was normal, but instead, you got a call from your doctor. Take a deep breath, and understand that the vast majority of mammography follow up does not result in a cancer diagnosis. In fact, more than one in ten women may be called back after a screening mammogram,[1] but fewer than one in ten of those women are found to actually have cancer.[2]

 

Screening vs. Diagnostic Mammogram

The annual mammogram recommended for women beginning at age 40 is what’s called a screening mammogram. It’s a simple, quick imaging test that looks for abnormalities in the breasts. If something abnormal is found, then the next step is often to schedule a diagnostic mammogram. This test will likely involve more images and will focus on a specific area of interest that was identified with screening mammography.

 

Other Follow-Up Procedures

Depending on what your mammography images show, you may also be referred for an ultrasound or MRI to get a better look at the suspicious area. If follow-up imaging indicates cancer may be present, then a biopsy will be performed to test for cancer cells in a sample of tissue.

 

Abnormal Findings in Screening Mammography

Abnormal findings can indicate many different things, only one of which is breast cancer. The American Cancer Society states that about half of women who get annual mammograms over a 10-year period will be called back for follow up that does not reveal cancer. Such false-positive findings are most likely in a first mammogram because the radiologist has no previous images with which to compare.[3] Recent research has also found that women aged 40–49 experience significantly higher recall rates (but not significantly different rates of cancer) than older women.[4]

 

What Can It Be?

A number of benign conditions can look suspicious on a mammogram. Some of the most common include

 

Dense Breast Tissue

Dense breast tissue can be difficult to distinguish from cancer or benign tumors because all of these features appear white on a mammogram. Use of advanced 3-D mammography can help identify invasive cancers in women with dense breasts while reducing recall rates.[5]

 

Cysts

Cysts are fluid-filled sacs that are almost always benign. They usually don’t require treatment, but if they cause discomfort, they can be aspirated.

 

Fibroadenoma

This is a type of solid, benign tumor that usually does not require treatment. If it is large or otherwise causes discomfort, however, it can be surgically removed.

 

Intraductal Papilloma

This is a small, benign type of tumor that grows in the milk ducts. Because they tend to cause pain, they are surgically removed. Typically, no further treatment is necessary.[6]

 

Calcifications

Calcifications are small calcium deposits that can appear in the breasts. They are not cancerous, but sometimes, they can suggest the presence of cancer. The radiologist will look closely about the size, shape, and patterns of calcifications to determine whether they warrant further investigation.[7]

This is not a complete list of benign breast conditions. Your mammography follow-up procedures will help the radiologist determine the reason for your specific abnormal finding.
