The U.S. Preventive Services Task Force (USPSTF) recommends that women at average risk for breast cancer start getting mammograms every two years at age 40 and continue until age 74. This is a change from the previous recommendation of starting at age 50. 

There is good news! Breastfeeding is a well-known protective factor against breast cancer, especially before menopause. Studies have found that the longer a woman breastfeeds, the lower her risk of breast cancer. 

However, breastfeeding women should still discuss breast cancer screening with their physician. Screening may be indicated for breastfeeding women at average risk of breast cancer. Screening is definitely indicated for breastfeeding women at high risk of breast cancer. 

Your physician may recommend a mammogram, breast ultrasound, or breast MRI, depending on your risk factors. 

Before you go for your breast imaging, here are some things to keep in mind: 

1. Breast Density: Breast tissue can be denser while breastfeeding, which might make it more challenging to interpret the mammogram results. However, experienced radiologists are trained to work with this.
2. Timing: If possible, it’s recommended to nurse or pump just before the mammogram. This helps reduce the amount of milk in the breast, making it easier to get clearer images.
3. Inform Your Technician: Be sure to let the radiology technician know you’re breastfeeding. They may adjust techniques to help ensure the most accurate results.
4. Alternative Imaging: Sometimes, ultrasound may be used in addition to or instead of a mammogram, especially in breastfeeding women, since it can provide clearer images of the dense tissue.

If you’re worried about a lump or other symptoms, don’t postpone getting imaging. Early detection is crucial, and a mammogram is a safe choice, even during breastfeeding.
