Could it be ovarian cancer that spread?

Patient: I have a 4.3 cm complex ovarian cyst on my right ovary that was accidentally found on a ct scan when I had upper abdominal pain. I also have a lymph node that has been slightly enlarged on the right side of my neck for at least 6 months. I have had an ultrasound and ct scan of my abodmen and pelvis, there are no other areas of concern, no ascites, etc. Could the two be linked?

Symptoms: lightheadedness
