Summary

The investigators hypothesize that an increase in dietary fiber intake during radiation therapy may provide better long-term intestinal health for the cancer survivor. If the hypothesis is not correct, the increased intake may only mean an increase in acute side effects. All participants are advised to consume at least 16 g of dietary fiber/day via food. In addition, participants are invited to take capsules that together contain either 5.5 g of dietary fiber from psyllium husk or placebo.
