A diagnosis of occult primary tumor is made if the primary tumor is not found during testing or treatment.
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis (chance of recovery) and treatment options depend on the following:
The number and size of lymph nodes that have cancer in them.
Whether the cancer has responded to treatment or has recurred (come back).
How different from normal the cancer cells look under a microscope.
The patient's age and general health.
Treatment options also depend on the following:
Which part of the neck the cancer is in.
Whether certain tumor markers are found.
