The purpose of this study is to study samples of rectal mucosa (the moist lining of the rectum) using a new light scattering technology, called partial wave spectroscopy (PWS) in patients who will undergo a standard of care colonoscopy or a flexible sigmoidoscopy and have a history of ulcerative colitis (UC).
The purpose of this study is to study samples of rectal mucosa (the moist lining of the rectum) using a new light scattering technology, called partial wave spectroscopy (PWS)in patients who will undergo a colonoscopy or a flexible sigmoidoscopy and have a history of ulcerative colitis (UC). PWS has been recently developed to allow scientists to learn about any changes to the cells that may indicate a risk of developing colon cancer. We believe that the PWS test will more accurately detect the risk of colon cancer.

Study samples of rectal mucosa (the moist lining of the rectum) using PWS.
Samples will be collected and then shipped to Northwestern University for analysis using PWS. This is to assess accuracy of detecting the risk for colon cancer.
