Is this CEA level good or bad?

Hi, Does anyone know if a CEA level of 1.7 is good or bad? My Mom found out by accident that she has a few somach ulcers surrounded by mostly diffuse signet cell adenocarcinoma that has invaded the linea propria (which , I understand, is the 2nd of 5 layers of the stomach).Her CAT scan was done and hopefully we will find out what results are tomorrow. The waiting is driving me crazy and any info. will be so helpful. Thanks. Ellen
