Since she started the chemotherpy she has a foul ordor that is very loud and smell very bad. they said because she had to have the colon packed because the tumor was lodged down in the rectal the doctor had to cut out the rectal and she had to have a colostopy bag place and it's not the colostopy bag that is smelling it is coming from her rectal area and this just started since she started chemotherpy. can you tell us why this foul smell and is it somthing that she can do about it. she baths five to six time a day and it still smell even after she come out of the tub. can you help me please :-(
