Tumor markers

I had my last chemo TX today.  Before the TX I had to see the Dr that was not my normal Dr.  I didn't like nor could I understand the idiot that came into the room today for all of about 4 minutes mind you......The nurse said my Tumor markers were up from the normal 10 that i have had most of the time to 25.. My question is should I be worried that they are going up.  I have to see this jackass DR in 3 weeks again becasue my Dr still won't be back.  She had a family emergency that is taking her out of the office for 8 weeks.

My DH who has been a huge support to me told me not to worry..LOL that's easier said than done thou.

Thank you for any advice
