Yes, MTF top surgery can affect your future mammograms. Mammograms are a type of X-ray that is used to detect breast cancer. They work by using X-rays to create images of the breast tissue.

If you have had MTF top surgery, the amount of breast tissue that is left behind will affect the accuracy of your mammograms. If you have had a double incision top surgery, which removes more breast tissue, your mammograms may be less accurate. This is because there is less breast tissue to be imaged.

If you have had a periareolar top surgery, which removes less breast tissue, your mammograms may be more accurate. However, it is still important to talk to your doctor about the risks and benefits of mammograms after MTF top surgery.

If you have had MTF top surgery, you may need to have more frequent mammograms or other types of breast cancer screening. This is because you are still at risk for breast cancer, even if you have had surgery.

It is important to talk to your doctor about your specific situation and to follow their recommendations for breast cancer screening after MTF top surgery.
