Plain-language summary
Colon cancer is the second most common cancer in men and women. It is a disease that can be prevented if it is found early. Colonoscopy is still the best screening tool for colon cancer and the polyps that turn into colon cancer. However, due to a variety of factors, including affordability, time, and age, not all patients are able to be screened. Researchers are working on other options for early detection that are as accurate as colonoscopy.
The purpose of this study if to determine if stool or blood can be used to detect colon cancers as early or earlier than colonoscopy. The researchers plan to use these samples to learn about specific proteins (also known as biomarkers) that may indicate colon polyps, colon cancer or an increased risk of developing colon cancer. In order to learn more about preventing and detecting colon and rectal cancer, we are collecting samples from subjects with cancer, adenomas, and colonoscopies who may be at risk for polyps.

* Pregnant or nursing women who otherwise meet the eligibility criteria may participate
* Subjects with one of the following:
* Colorectal adenocarcinoma-not treated and in colon at time of stool collection (CRC bin)
* Adenoma-pathologically confirmed adenoma present in colon at time of stool collection (Adenoma Bin)
* Higher Risk Non-neoplastic Bin
* Subjects with a personal history of adenomas (confirmed by pathology) with none present on qualifying colonoscopy
* Subjects with a personal history of CRC (longer than 3 years ago because of exclusion criteria of cancer within last 3 years) with none present at time of qualifying colonoscopy
* Any family history of CRC (1st degree relative)
* Current positive screening stool test for blood, for DNA or for both within 12 months with no follow-up intervention.
* Average Risk, Non-neoplastic Bin
* No history or current finding of any colorectal neoplasia including CRC, adenomas, sessile serrated adenomas and no family history of CRC.
* Subjects who had CRC that was successfully treated at least three years ago may be considered eligible for the adenoma bin if their polyps are adenomas and there is no evidence of CRC, or for the higher risk non-neoplastic bin as noted…
