August 13, 2026 updated by: Joseph McCollom
The purpose of this research study is to see how the brain changes in patients receiving chemotherapy (cytotoxic drug) treatment for colon or rectal cancer at Parkview Cancer Institute. This information will be used to identify helpful tests to diagnose individuals at risk for developing difficulties with thinking and memory due to their cancer treatments.
