Inconclusive (hate that word!)

It all started with a routine PAP smear,
in which the gynecologist noted that the Lymph node
glands in my neck, were "grossly enlarged".
(not good for a person with Lymphoma -
even if it is in remission)
So, Dr. Zu, my oncologist, ordered a PET scan,
to see the status of my cancer.
(PLEASE don't be back Cancer, I do not want you here!)
The PET Scan was inconclusive. WTF?!
Dr. Zu is "not convinced the cancer is back" BUT
is "concerned about my enlarged lymph nodes"
He said we will give it a month or 2, and if the swelling still exists
He wants me to have a biopsy ;-(
