The Early Detection Research Network (EDRN) is a collaboration led by the National Cancer Institute (NCI) focused on the discovery of cancer biomarkers. The effort, started in 2000, includes both principal investigators and associate members from leading research institutions across the United States.
[14] [15] Early detection through screening is useful for cervical and colorectal cancer. [11] The benefits of screening for breast cancer are controversial. [11] [16] Cancer is often treated with some combination of radiation therapy, surgery, chemotherapy and targeted therapy.

A typical application is the detection of a tumor. For instance, some hospitals use CAD to support preventive medical check-ups in mammography (diagnosis of breast cancer), the detection of polyps in colonoscopy, and lung cancer. Computer-aided detection (CADe) systems are usually confined to marking conspicuous structures and sections.
