I have 4 and 5mm internal iliac nodes lighting up on my last PET/CT?

I have 4 and 5mm internal iliac nodes lighting up on my last PET/CT. Are they too small for fine needle aspiration. I am 3 months post colorectal cancer treatment. The original tumor is no longer evident. I have concern about metastasis.
Thanks

Hi..
The lymph nodes does not seem abnormal pertaining to the size..
So my suggestion is to wait and watch..
In case if size continue to grow then you should get FNAC done..

Hope this helps..

Regards..
