question: Dear doctor My father is diagnosed with uknown primary tumor in the lumph in the stomache. He got the diagnose last year sep. 1. 2010 after beeing sick in pain for 4 month. He was treated with kemo for about 6 month and i shrank, but nok the last time in the month April, so they started giving him a new type of kemo, and we just got the result yesterday that til got 20% bigger that in may, now they say that they have given him the only 2 types of different kemo treetment they have in Denmark, and the only thing they can offer him is to put him up as candidate for an experiment ( not kemo )  Do You have any experience with that type of disease or know anyone in the world that has? Regards Heidi
