This pilot clinical trial studies how well personalized dietary intervention works in managing bowel dysfunction and improving quality of life in stage I-III rectosigmoid cancer survivors. Personalized dietary intervention may help people understand bowel symptoms, identify helpful and troublesome foods for bowel symptoms, adjust diets and food preparation based on food triggers, and coach on healthy diet recommendations after cancer treatment.

PRIMARY OBJECTIVES:

I. Administer and determine the feasibility of the personalized dietary intervention.

II. Using qualitative methods, evaluate the acceptability of the intervention as reported by survivors.

III. Explore decisional conflict associated with treatment decision-making in rectal cancer surgery.
