The David C.

We treat many kinds of cancers, including:

Our digital imaging system connects all of our imaging, radiation and nuclear medicine equipment, so images and test results are instantly available to physicians. This means you and your doctor can discuss results and make treatment decisions in a timely manner.

We recommend you get the cancer screenings that will help detect cancer at early stages: mammograms beginning at age 45, colonoscopies at age 50, skin cancer screenings at the first sign of unusual moles or markings on your skin and lung cancer CT screenings if you have been a smoker.
