Vin, just to add a note to all of the good advice above-my husband's last radiation tx was almost 4 months ago. He is still struggling with the mucous and phlegm, but it comes and goes now, and some days are much better than others. His Doc's standerd response is "time will make it better", so there are no quick fixes out there. Tell your family member to hang in there and give him\her lots of support. Amy
