Can PET Scans Track Breast Changes? Expert Advice on Follow-Up Care

Follow-up issues

Hello Doctor, I have been undergoing breast ultrasounds every six months to a year for the past 4 to 5 years.
This year, I am also eligible for a mammogram, which is scheduled for next month in December.
Additionally, I have been experiencing throat discomfort for the past 8 months.
I had a PET scan at the end of September, which indicated a suspicious lesion in the epiglottis area, but there were no abnormalities found elsewhere in my body.
Can the PET scan detect any changes or issues in the breast, or should I still proceed with this year's ultrasound and mammogram? I would appreciate your advice.
Thank you.

Although the PET scan did not reveal any issues with the breast, I still recommend undergoing a breast ultrasound and mammography.

More Info

PET scans, or Positron Emission Tomography scans, are advanced imaging techniques that can provide valuable information about metabolic activity in tissues, including breast tissue. However, they are not typically used as a primary method for tracking changes in breast tissue, especially in the context of routine breast cancer screening or follow-up care. Instead, mammograms and breast ultrasounds are the standard imaging modalities employed for monitoring breast health.

In your case, you have been undergoing regular breast ultrasounds for several years, which is an excellent approach for monitoring any changes in breast tissue. These ultrasounds can detect cysts, solid masses, and other abnormalities that may require further evaluation. Additionally, you mentioned that you are now eligible for mammography, which is a critical tool for breast cancer screening, particularly for women over the age of 40 or those with a family history of breast cancer.

While PET scans can identify areas of increased metabolic activity, they are generally used to assess known cancers, evaluate treatment response, or detect metastasis rather than for routine screening. The sensitivity of PET scans for breast cancer is lower compared to mammography and ultrasound, especially in detecting small tumors. Therefore, it is not advisable to rely solely on a PET scan for tracking breast changes or issues.

Regarding your specific situation, since you have already scheduled a mammogram and continue to have breast ultrasounds, it is essential to proceed with these tests as planned. The mammogram will provide a comprehensive view of breast tissue and help identify any calcifications or masses that may not be visible on ultrasound. The combination of both imaging techniques will give your healthcare provider a clearer picture of your breast health.

As for the PET scan you underwent due to concerns in the epiglottis area, it is crucial to follow up with your healthcare provider regarding the findings. If the PET scan indicated a suspicious area, further evaluation may be necessary, but this does not negate the importance of your scheduled breast imaging.
In summary, while PET scans can provide useful information about metabolic activity in various tissues, they are not a substitute for mammograms and ultrasounds when it comes to breast health monitoring. It is essential to continue with your scheduled breast imaging to ensure comprehensive care and early detection of any potential issues. Always consult with your healthcare provider for personalized advice and to address any concerns you may have regarding your health and the appropriate follow-up care.
