Does anyone out there know anything about cancer marker tests and non-secretor status?  It seems I read somewhere that they may not be accurate for non-secretors.  Does anyone know how they are thrown off (too high, low, or just not valid)?  Would really like to find out--mentioned this to my oncologist who looked at me as if I was crazy(nothing new of course)  Thanks, Bee

hello and welcome on our board,

yess there's an issue with us and the tumormarkers....I do have clients where altimes tumormarkers
show up a higher amount....also a +++ for cancer issue...but then if you get into deeper tests, nothing appears, mostly the A's are prone for that....what I observed in the last 3 years ......
