This study is testing a new web-based program called CRCweb for people with colorectal cancer who are getting chemotherapy, and their caregivers. Colorectal cancer is a type of cancer that affects the colon and rectum. Chemotherapy is a treatment that uses drugs to kill cancer cells. People with this cancer often have symptoms like feeling very tired, sad, trouble sleeping, pain, and trouble thinking clearly.
