Mammogram vs. Ultrasound
Most women are familiar with the mammogram procedure, which is used to detect breast cancer and other problems in breast tissue. Another procedure that can be used to evaluate breast tissue is an ultrasound breast exam. Given that there are certain drawbacks to mammograms, including that they use a small amount of radiation and are somewhat uncomfortable, why isn’t an ultrasound used exclusively for breast assessment? There are a number of reasons.

The answer to the question, “Which is better, a mammogram or an ultrasound breast exam?”, is based on many considerations. Generally speaking, mammograms are for screening purposes whereas ultrasounds are more often used for diagnosing conditions affecting breast tissue. Beyond that, there are pros and cons for each procedure.
