Hi there.
Thank you for your question.
I will be helping you out with your queries.
The levels of CEA vary from one person to another depending on the number of metastases.
So the lower the CEA levels the lesser the number of mets.
Customer: replied 1 year ago.

I am confussed as my father has ;

about 9 liver mets ( all small except 1 large )

4 peritoneal nodules (7mm)

1 aortocaval node 2 cm

the above seems quite alot of mets right ? His cea fete round 2 chemo is 55 but before chemo was 65

Expert:  Dr. SH replied 1 year ago.
The number of mets is a lot but their sizes are generally small which is why the CEA level is not as high.
Customer: replied 1 year ago.

Is it better cea is lower than high

also although cea dropped from 65 to. 55 can it go up again. ?

Expert:  Dr. SH replied 1 year ago.
It is better to have a lower CEA level.
It can go back up again if the mets increase in number or size.
Customer: replied 1 year ago.

So u dont think the fact he had the chemo stopped

when there was still half hour left will make a difference ?

Expert:  Dr. SH replied 1 year ago.
I do not think half an hour left in chemo should make a lot of difference.
I would appreciate it if you rate me.
