Do I have to get any blood tests when I go for a mammogram?

No. Mammogram can result in an ultrasound and possibly even a biopsy which some institutions do the same day, but usually this is scheduled for another day if it is deemed necessary. No blood test is standard in preparation for a mammogram.
Nope. A mammogram does not involve any form of blood tests. Get your exam, have your mammogram, and discuss with your doc which blood tests would benefit you for the remainder of your health screening.
No. No blood tests are necessary. There are no injections, it is simply a low dose X-ray of your breasts.
