Cancer Screenings

We recommend cancer screenings to 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.

Breast Cancer Screening

The American Cancer Society recommends annual mammograms for women beginning at the age of 45. We offer screening and diagnostic mammograms (including 3D Mammography) with expert follow-up care. Visit our Mercy Breast Center to schedule yours today:

Lung Cancer Screening

Lung cancer symptoms may not show up until an advanced stage. Screening with a low-dose CT (LDCT) can detect lung cancer earlier than ever, which can improve chances of surviving. It’s recommended for people age 55-77 with risk factors for lung cancer.

Colon Cancer Screening

The American Cancer Society recommends annual colorectal cancer screening beginning at the age of 45. Mercy primary care doctors and Mercy colon specialists can help determine which screening test is best for you. Colorectal cancer can be hereditary and genetic testing is available.
