Is it okay to assume that a follow-up evalution is a cause for alarm after taking a mammogram?

No, but follow up: A follow up is necessary for us to get a closer look at an abnormality seen on your initial mammogram. In most cases, the abnormalities look noncancerous. You may be asked to come back in 3-6 months for another evaluation.

Not necessarily: Routine mammograms are initially done with a "screening" technique. If the radiologist sees an area that is questionable, (s)he may call you back to do what is called a "diagnostic" mammogram, which includes more focused views of the possible abnormality, and/or ultrasound of the breast. Many times these extra tests show nothing of concern. Try not to worry yet.

No: I wouldn't assume anything of the sort. If they are recommending a 6 month followup, the chance of cancer is less than 2%. If they are recommending additional views based on the screening mammogram, most of these turn out to be of no concern. However, a minority do turn out to be suspicious, so you need to complete the evaluation.
