I don't see that anyone has mentioned this, but constipation during treatment is something everyone deals with, and it is not related to the chemo, but the pain meds usually. Most of the heavy duty pain medications will stop things up. So all throughout treatment to take some kind of stool softeners routinely, regardless of when you have had treatments or when you take your pain meds, is the best plan.
