your doctor is being thorough. trying to give you a more definite answer based on the results of both tests. there is always a cause to be concerned so your doctor is trying to alleviate any diagnostic uncertainty.
i am 34 years old my doctor has confirmed breast nodules. should i worry that my dr. ordered both a mamm and ultrasound? . i have been told the ultrasound is usually ordered based on the mammogram results. i wondered if it was cause for concern that he was shotgunning them both at once same day one after the other.
